Guanacaste is Costa Rica’s Pacific crown — a sun-scorched province of volcanic mountains, tropical dry forest, and some of the most varied coastline in Central America. Fly into Liberia’s Daniel Oduber International Airport (LIR) and within an hour you can be standing on white sand with turquoise water stretching to the horizon. Drive a little farther and you’ll find beaches so remote you might spend the whole day without seeing another person.
This guide covers 12 of the best beaches in Guanacaste — a mix of the famous and the genuinely off-the-radar, chosen to give every type of traveler a reason to come. Whether you’re after world-class surf, calm water for the kids, exceptional diving, or total wilderness, Guanacaste has it. Here’s where to find it.
Best time to visit: December through April (dry season) for guaranteed sunshine. July–August brings a brief dry spell and is also excellent. The rainiest months are May–June and September–November — lower prices, empty beaches.

1. Conchal Beach — The Shell Beach That Has to Be Seen to Be Believed
Location: Cabo Velas, Santa Cruz — between Mina and Brasilito beaches GPS: 10.403061, -85.803356 | Postal code: 50308
Conchal is not like other beaches. Instead of sand, the entire shore is covered in hundreds of millions of tiny crushed shells, creating a pale, ivory-colored surface that crunches softly underfoot and gives the water an almost impossible shade of turquoise. Swimming here is something travelers talk about for years — the water is so clear that you can watch tropical fish weaving around your legs without putting on a mask.
Beyond the unique shoreline, Conchal offers a full range of activities for those who want more than a beach chair: snorkeling, open-sea fishing, diving, jet skiing, ATV tours, and horseback riding are all easily arranged nearby. The beach itself is shaded by trees, which makes an afternoon here far more comfortable than on exposed stretches of coast.
Getting there from Liberia Airport (LIR): About 1 hour. Drive south to Belén, turn right and follow the road to Huacas, then right toward Flamingo/Conchal for about 4.5km to Brasilito. Turn left at Brasilito and continue through to Conchal beach.
Getting there from San José (SJO): About 4 hours via Highway 1 north.
By bus: San José – Huacas – Flamingo – Brasilito route (Tralapa, +506 2221-7202), then a 5-minute taxi to Conchal.
By plane: Direct flights from San José to Tamarindo airport (Sansa), then about 15 minutes by car.
Tip: Arrive early — the beach and parking fill up by mid-morning on weekends during high season.

2. Flamingo Beach — Guanacaste’s Upscale Pacific Gateway
Location: Cabo Velas, Santa Cruz — between Brasilito and Potrero beaches GPS: 10.439006, -85.793009 | Postal code: 50308
Flamingo is where Guanacaste cleans up and puts its best foot forward. White sand, calm water, a full-service marina, and an established strip of restaurants, hotels, and shops make it the most comfortable and convenient beach destination in the region. It’s also the hub for sailing and sport fishing charters that explore the coastline north and south, and the calm bay makes it one of the safest options for families with young children.
Unlike the more rustic beaches further up and down the coast, Flamingo won’t catch you off guard — everything you need is within easy reach. That’s the point. It’s a beach you can base yourself at for a week and use as the anchor for day trips to quieter spots like La Penca or Conchal.
Getting there from LIR: About 1 hour — same route as Conchal to Brasilito, then continue north toward Flamingo.
Getting there from SJO: About 4 hours.
By bus: San José – Huacas – Flamingo – Brasilito route (Tralapa, +506 2221-7202).
By plane: Flights to Tamarindo airport, then about 20 minutes by car.
Tip: Accommodation books up fast December through April. If you’re planning a dry-season trip, reserve at least 2–3 months in advance.

3. Brasilito Beach — The Laid-Back Village Next Door to Conchal
Location: Cabo Velas, Santa Cruz — between Conchal and Flamingo beaches GPS: 10.407337, -85.797627 | Postal code: 50308
Brasilito sits directly between two of Guanacaste’s most popular beaches — Conchal and Flamingo — and somehow feels like neither of them. While those two have been shaped by tourism and money, Brasilito has held onto its character as a small fishing village with gray sand, blue water, and a genuinely relaxed pace of life. It also has one big practical advantage: it’s significantly more affordable, with a wide range of budget-friendly hotels, restaurants, and services that the fancier neighbors can’t match.
It’s a natural base for exploring the area. Walk south at low tide and you’ll reach Conchal without ever getting in a car. The nearby Las Baulas Marine National Park is one of the world’s most important leatherback sea turtle nesting sites — a rare and unforgettable thing to witness if your timing lines up (nesting season runs October through February).
Getting there from LIR: About 1 hour — same route as Conchal; the bus stop is right at the beach.
Getting there from SJO: About 4 hours.
By bus: San José – Huacas – Flamingo – Brasilito route (Tralapa, +506 2221-7202); ask for the Brasilito stop. About 4 hours.
By plane: Tamarindo airport, then about 15 minutes by car.
Tip: Walking to Conchal at low tide (just head south along the beach) is free and takes about 20 minutes. Check tide times before you go.

4. La Penca Beach — Guanacaste’s Best-Kept Secret
Location: Tempate, Santa Cruz — between Potrero and Prieta beaches GPS: 10.460002, -85.775671 | Postal code: 50304
There are beaches in Guanacaste that everyone knows about, and then there is La Penca. This small semi-sheltered bay — less than 1km of white sand mixed with shell and coral fragments — sits between Potrero and Prieta beaches and somehow stays almost completely undiscovered. The water is turquoise, calm, and clear almost year-round. An estuary and mangrove swamp at one end add a lush, wild dimension that the more manicured beaches in the area don’t have.
La Penca doesn’t have the infrastructure of Flamingo or the fame of Conchal, but that’s entirely the point. It’s described on its own page as “a well-hidden treasure” — and it genuinely is. If you want a day at a beautiful Guanacaste beach without sharing it with a crowd, make the detour.
Getting there from LIR: About 1.5 hours. Drive south to Belén, then toward Huacas, then right toward Flamingo for about 4.5km to an intersection. Follow signs toward Potrero/La Penca and continue 4.5km more to a small commercial center, then turn left to the beach.
Getting there from SJO: About 4–5 hours.
By bus: San José – Flamingo – Potrero route (Tralapa, +506 2221-7202 or +506 2680-0392); stop at Potrero, then a short taxi ride.
Tip: Visit at low tide when the full beach is accessible. The estuary at the south end is worth exploring on foot — bring water shoes.

5. Avellanas Beach — “Little Hawaii” and One of Costa Rica’s Best Surf Spots
Location: Tamarindo, Santa Cruz — between Negra and Tamarindo beaches GPS: 10.2275, -85.836689 | Postal code: 50309
Locals call Avellanas “Little Hawaii.” It’s not an exaggeration. Offshore swells here regularly reach 18 feet, making it one of the most respected surf breaks in Costa Rica and a destination that draws serious surfers from around the world. The beach is jungle-backed, the atmosphere is unpretentious, and there’s none of the resort-town energy you find in Tamarindo just up the coast.
Non-surfers are welcome too — and often pleasantly surprised. Avellanas is a beautiful stretch of coast for an afternoon, and Lola’s bar on the beach has built a genuine reputation: good food, strong drinks, and music that makes the place feel like a discovery. Horseback rides along the shore are also popular. Just skip the swimming — strong currents make it unsafe for anyone not riding a surfboard.
Getting there from LIR: About 1.5 hours. Drive to the Tamarindo area, then head south about 30 minutes on a dirt road. A 4WD vehicle is recommended in the rainy season (May–November).
Getting there from SJO: About 4–5 hours.
By bus: San José – Tamarindo route, then a local taxi or rental car heading south (~30 min).
Tip: This is a cash economy — bring colones. Accommodations are affordable and there are a few good surf camps if you want lessons or board rentals.

6. Tamarindo Beach — The Classic Guanacaste Experience
Location: Tamarindo, Santa Cruz — between Langosta and Grande beaches GPS: 10.303414, -85.839303 | Postal code: 50309
If you’re visiting Guanacaste for the first time, Tamarindo is probably already on your radar — and for good reason. It’s the most complete beach destination in the region, where you can go from a morning surf lesson to an afternoon snorkeling trip to a sunset sailing charter to a night out at a proper restaurant, all without getting in a car. The nearby Las Baulas Marine National Park is one of the most important leatherback turtle nesting sites in the world, and the adjacent Diria National Wildlife Refuge adds serious nature credentials to what could otherwise feel like a pure tourist town.
The tradeoff is crowds. In high season (December–April), Tamarindo is busy, prices are high, and the beach is shared. But for travelers who want maximum options and easy logistics, nothing else in Guanacaste competes.
⚠️ Safety note: Tamarindo has strong rip currents and barely submerged rocks — swim with care and pay attention to posted flags. The estuaries at both ends of the beach are dangerous to cross at medium to high tide.
Getting there from LIR: About 1 hour. Drive south to Belén, then Huacas, then Tamarindo (8km from Huacas, then 4km into town).
Getting there from SJO: About 4 hours.
By bus: San José – Tamarindo direct (Alfaro-Tracopa, +506 2222-2666). Buy your ticket the day before. About 4–5 hours.
By plane: Sansa and Aerobell both fly direct to Tamarindo airport from San José. The beach is 5 minutes from the airport.
Tip: Shoulder season (May–June and November) offers the same beach at significantly lower prices and thinner crowds.

7. Carrillo Beach — Coconut Palms, Stunning Sunsets, and Blissful Quiet
Location: Puerto Carrillo, Hojancha — between Camaronal and Samara beaches GPS: 9.869639, -85.498975 | Postal code: 51103
Carrillo is one of those beaches that repeat visitors return to year after year and rarely tell anyone about. It has everything Samara has — long white sand, crystal clear water, forested hills as a backdrop, and genuinely spectacular sunsets — but on a much smaller, quieter scale. The community is a modest fishing and farming village with a healthy enough tourist infrastructure that you won’t go without, but not so much that it changes the character of the place.
The beach itself runs along a gorgeous natural bay bordered by coconut palms and cliffs, with calm enough water for comfortable swimming and clear enough conditions for snorkeling and scuba diving. At low tide, the rocky platforms reveal tidal pools worth exploring. Sport fishing here is excellent. And the sunsets — multiple travelers and guides consistently put Carrillo among the best in Guanacaste for this.
Getting there from LIR: About 2.5 hours. Drive south to Nicoya, then toward Samara via Hojancha, then continue south to Carrillo.
Getting there from SJO: About 5 hours via the Nicoya Peninsula route — a scenic drive through rural Costa Rica.
By bus: San José – Samara (Terminal Alfaro, +506 2222-2666), then a local bus from Samara to Carrillo (about 1 hour). Buy your ticket the day before.
By plane: Sansa and Aerobell fly to the Samara/Carrillo airport. The beach is minutes away.
Tip: This is a deliberate rest destination — minimal noise, minimal distractions. If you need nightlife, you’re in the wrong place. If you need to decompress, you’re exactly right.

8. Hermosa Beach (Guanacaste) — Calm, Blue-Flag Certified, and One of the Best Dive Sites in the Country
Location: Sardinal, Carrillo — between Punta Cacique and Bonita beaches, Gulf of Papagayo GPS: 10.576574, -85.676565 | Postal code: 50503
Important: Costa Rica has several beaches named Hermosa. This one is in Guanacaste (Sardinal, Carrillo canton), in the Gulf of Papagayo. The famous surf beach called Hermosa is near Jacó in Puntarenas — an entirely different location. Make sure your GPS is pointed at the right one.
Hermosa in Guanacaste is a 2km stretch of white sand and calm blue water that holds the Blue Flag environmental certification — an award given to beaches that meet high standards for environmental quality and safety. It’s beautiful by any measure, but what makes it genuinely special is what’s underwater. The marine life here is exceptional, and the beach is consistently rated as one of the top dive sites in Costa Rica. Swimmers love it too, since the water stays calm and clear most of the year.
Development is beginning to creep in at the northern end of the beach, where luxury resorts are going up. The south remains quiet and relaxed — head there if you want the beach mostly to yourself.
Getting there from LIR: About 45 minutes — one of the closest quality beaches to the airport. Drive south about 8km, turn right at the DO IT Center toward Papagayo/Panama beach, then turn right and follow the road about 4km to the Hermosa Beach entrance.
Getting there from SJO: About 5–6 hours.
By bus: San José – Liberia route (Pulmitan, +506 2222-1650), then rent a car or take a taxi from Liberia (about 45 minutes).
Tip: Book with a local dive operator in advance during peak season — this is a popular dive destination and spots fill up.

9. Junquillal Bay Beach — A Wildlife Refuge Beach with Blue Flag Status and Camping
Location: Santa Elena, La Cruz — between Cuajiniquil and Manzanillo beaches, Gulf of Santa Elena GPS: 10.968915, -85.687695 | Postal code: 51004
Junquillal Bay sits in the far northwest of Guanacaste, tucked inside the Junquillal Bay Wildlife Refuge and almost entirely surrounded by tropical dry forest that hasn’t been cleared or developed. The beach is white sand with crystal blue water and gentle waves — calm enough for long walks, snorkeling, light diving, and fishing. It holds the Blue Flag certification for health and safety. And it has one of the best beach camping setups in Guanacaste.
This is a beach for travelers who want a genuine natural experience. The nearly intact forest, the wildlife refuge status, the Gulf of Santa Elena — it all adds up to something that feels significantly more remote and pristine than beaches closer to the main tourist centers. It’s also genuinely quiet. Very few people make it out here, which is part of what makes it worth the drive.
Getting there from LIR: About 1–1.5 hours. Drive north on the Pan-American highway about 50km past Liberia, turn left toward Junquillal, then 9km to the beach.
Getting there from SJO: About 5–6 hours.
By bus: No direct bus to Junquillal Bay. Take San José – Liberia (Pulmitan, +506 2222-1650, about 5 hours), then Liberia – Cuajiniquil from the González García terminal (about 1 hour), then a taxi about 15 minutes to the beach. Buy the Liberia bus ticket the day before.
By plane: Liberia airport (LIR) is your gateway — rent a car for the drive north.
Tip: The camping facilities here are among the best in the region for a beach camp. Bring your own food and supplies — services in the immediate area are very limited.

10. Cabuyal Beach — 30km from Liberia and Feels Like the Edge of the World
Location: Nacascolo, Liberia — between Nacascolito and Naranjo beaches GPS: 10.675708, -85.652225 | Postal code: 50104
Some beaches make it easy. Cabuyal is not one of them — and that’s the entire appeal. About 30km from the city of Liberia, the last 6km requiring a 4WD vehicle over a rough road, Cabuyal is a remote, white sand beach with crystal-clear turquoise water surrounded by tropical dry forest, backed by the Cabuyal Punta headland and estuary on one side and the Cabuyal Hill with rocky outcrops on the other. The result is almost intact, extraordinary natural scenery — and almost no one there to see it with you.
If you want a Costa Rica beach where you can spend the whole day without seeing another tourist, this is a serious answer. Camping is possible. There are no facilities. You bring everything or you go without.
Getting there from LIR: About 1.5 hours. Drive south about 8km, turn right at the DO IT Center heading north, follow the road about 15km, turn left and continue about 6km on rough road to the beach. 4×4 required.
Getting there from SJO: About 5–6 hours.
By bus: No buses serve Cabuyal. San José – Liberia (Pulmitan, +506 2222-1650), then rent a 4WD or take a taxi from Liberia (about 1 hour).
Tip: Bring everything — food, water, sunscreen, emergency supplies. There is nothing at the beach itself and very little in the surrounding area. Fill up on gas in Liberia before turning off the highway.

11. Blanca Beach (Liberia) — A Pristine Cove Inside the Gulf of Papagayo
Location: Nacascolo, Liberia — between Nacascolo and Virador beaches, Gulf of Papagayo GPS: 10.644874, -85.646908 | Postal code: 50104
Blanca Beach in Liberia is one of the most beautiful and least accessible beaches in Guanacaste — which is not a coincidence. The beach sits inside the grounds of the Four Seasons Resort at Peninsula Papagayo, and reaching it requires driving to the hotel’s visitor parking (~24km from the main highway turnoff), taking a private hotel minibus to the trailhead, and then descending 750 steps to the cove below. The beach itself has no facilities whatsoever.
What you find at the bottom is a short, pristine stretch of white sand with turquoise water, a unique natural bridge formed with the neighboring Virador Beach connecting Punta Mala, and the kind of seclusion that most Guanacaste beaches stopped offering years ago. Snorkeling and diving here are excellent. As a public beach, access is legally guaranteed — the logistics just require planning and effort.
Getting there from LIR: About 1.5 hours to the parking area. Drive south ~8km from Liberia, turn right at the DO IT Center toward the Four Seasons Hotel, then follow the road about 24km to the visitor parking. Hotel minibus + 750-step trail from there.
Getting there from SJO: About 5–6 hours.
By bus: No buses. Rental car or taxi from Liberia.
Tip: Wear proper shoes for the steps — not flip flops. Bring all your own food, water, and snorkeling gear. There is nothing at the beach itself and no services along the trail.

12. Blanca Beach (La Cruz) — Inside Santa Rosa National Park, at the End of 17km of Dirt Road
Location: Santa Elena, La Cruz — within Santa Rosa National Park, between Morritos beach and Santa Elena Bay GPS: 10.938197, -85.861148 | Postal code: 51004
This is Costa Rica’s wildest beach on this list — and possibly the most remote public beach in all of Guanacaste. Blanca Beach in La Cruz sits deep inside Santa Rosa National Park. To get there, you must turn off the Pan-American highway about 40km north of Liberia, drive 15km on a dirt road to the Murcielago ranger station (where you must check in), and then continue another 17km on a road in very poor condition. A 4WD vehicle is not optional — it’s essential.
What waits at the end is a completely untouched white sand beach with crystal blue water, part of the broader Santa Elena Bay area, and the kind of absolute quiet that’s nearly impossible to find anywhere else in the country. Snorkeling, diving, and kayaking are all excellent here. The marine life has had very little human pressure, and it shows. This is a true expedition — plan it as one.
Getting there from LIR: About 2–3 hours total. Drive north ~40km past Liberia on the Pan-American, turn left toward Cuajiniquil, then 15km on dirt road to park entrance, then 17km more to the beach. 4×4 mandatory.
Getting there from SJO: About 6–7 hours.
By bus: No buses. A rental 4WD is the only realistic option.
Tip: Fill up completely on gas in Liberia. Bring all supplies — food, water, first aid, spare tire. Tell someone where you’re going before you head out. This is extraordinary, but it demands preparation.

How to Choose the Right Guanacaste Beach for You
All 12 beaches on this list are beautiful. The right one depends on what you’re looking for:
Flying into Liberia and want the shortest drive? Hermosa Beach (Guanacaste) is about 45 minutes from the airport — white sand, calm water, excellent diving, Blue Flag certified.
Traveling with young kids? Conchal and Flamingo both have calm water, full services, and safe conditions for families. Brasilito is the budget-friendly version of the same area.
Here to surf? Avellanas is where the serious swells are. Tamarindo has lessons and rentals for all levels.
Want the best snorkeling or diving? Conchal, Hermosa (Guanacaste), and Junquillal Bay are your top picks. Blanca Beach (Liberia and La Cruz) are exceptional if you’re willing to work for it.
Looking for the most beautiful sunsets? Carrillo and La Penca consistently come out on top — quiet, uncrowded, and facing the Pacific horizon at the right angle.
Want a beach almost entirely to yourself? Cabuyal and Blanca (La Cruz) are as remote as public beaches get in Costa Rica. Junquillal Bay and La Penca are remote without requiring a 4WD expedition.
Traveling on a budget? Brasilito and Avellanas both have affordable accommodations and food — a fraction of the cost of Flamingo or Tamarindo.

Frequently Asked Questions About Guanacaste Beaches
What is the most beautiful beach in Guanacaste, Costa Rica? Conchal Beach is widely considered the most striking for its unique shell-covered shore and extraordinarily clear turquoise water. La Penca, Flamingo, and Hermosa are strong runners-up for white sand and calm conditions.
Which Guanacaste beaches are safe for swimming? Conchal, Flamingo, Brasilito, Hermosa (Guanacaste), Junquillal Bay, and Carrillo all have calm, swimmable conditions. Avoid swimming at Avellanas due to strong currents, and exercise caution at Tamarindo where rip currents and submerged rocks are a real hazard.
How far are Guanacaste beaches from Liberia Airport? Most are between 45 minutes and 2 hours from Daniel Oduber International Airport (LIR). Hermosa Beach (Guanacaste) is the closest at about 45 minutes. Flamingo, Conchal, and Tamarindo are all around 1 hour. Carrillo is at the farther end at about 2.5 hours.
What is the best time of year to visit Guanacaste beaches? December through April is the dry season — the most reliable time for sunshine and calm conditions.

May–June and September–November are the rainiest months, but hotels are significantly cheaper and beaches are far less crowded.
Are there secluded beaches in Guanacaste? Yes — several. Cabuyal, Blanca Beach (La Cruz, inside Santa Rosa National Park), Junquillal Bay, and La Penca are among the least-visited beaches in the region.
