The 10 Most Interesting Things to Do on Costa Rica's Caribbean Coast

The southern Caribbean coast of Costa Rica is not a checklist destination. It’s a strip of reef, jungle and small towns running from Cahuita down to Manzanillo, and the best days here are the ones where you do one good thing and then go swimming.

I lived in Costa Rica for five years and I keep coming back to this coast. This list is my ranking of what’s genuinely worth your time, with the facts checked and the prices dated so you can plan around them.

How I ranked these

I weighed three things: how unique the experience is to this coast, how good it is for the money and effort, and how well it holds up on an average day rather than a perfect one. Wildlife and reef experiences rank high because that’s what this coast does better than almost anywhere else in the country.

I checked prices in September 2026, mostly on each operator’s or park’s own site; where sources disagree, I say so. Prices change, so treat them as a guide and confirm before you go.

The list

1. Cahuita National Park — the one thing you shouldn’t skip

Cahuita is the reason a lot of people come to this coast in the first place. It started as the Cahuita National Monument in 1970 and became a national park in 1978, and it protects about 1,106 hectares of land and 22,300 hectares of sea.

The sea part is the headline. The park’s reef holds at least 35 species of coral and 123 species of fish, and snorkeling is only allowed with an official guide to protect it. On land, a flat coastal trail runs from Cahuita town toward Punta Cahuita and Puerto Vargas, with howler monkeys, capuchins, coatis and sloths along the way.

Entry at the Playa Blanca sector in town is by voluntary contribution. For the Puerto Vargas sector, sources disagree: Cahuita.cr lists $4 (₡2,500) for foreigners and hours of 7 a.m. to 4 p.m., while an undated Visit Costa Rica blog post lists $5 and 8 a.m. to 4 p.m. Budget about $4–5 and check at the gate.

Best for: Almost everyone, from kids to serious naturalists.

Honest downside: The trail is hot, humid and often muddy, and you can’t just grab a mask and swim the reef on your own.

2. Swim at Punta Uva — the best beach day on the coast

Punta Uva was ranked #41 on The World’s 50 Best Beaches 2025, and according to The Tico Times it was the only Costa Rican beach on that list. The same article notes that its calm waves make it ideal for swimming and snorkeling, and that the lack of heavy development keeps it peaceful.

That matches my judgment. Punta Uva is the beach I’d send a nervous swimmer, a family with small kids, or anyone who just wants to float, because calm water is exactly what it’s known for.

Best for: Swimmers, families, anyone who wants a slow day.

Honest downside: There are few services right on the sand, so bring water and snacks.

For where to put your towel and when to go, see my Punta Uva beach guide. If you want to stay right on it, I’m partial to Tree House Lodge, which Oyster’s review describes as having direct access to Punta Uva beach, on 10 acres inside the Gandoca-Manzanillo refuge. Full disclosure: the lodge’s owner is a friend of mine (no financial stake), so weigh my enthusiasm accordingly.

3. Hike Gandoca-Manzanillo Wildlife Refuge — the wildest walk on the coast

Where the road ends in Manzanillo, the jungle keeps going. The refuge protects about 45.66 square kilometers of land and 59.23 square kilometers of sea, and it’s one of only two places in Costa Rica where manatees still occur.

The main trail from Manzanillo toward Punta Mona runs about 5 km and takes around 2.5 hours there and back, with a lookout at Miss May Point only about 15 minutes from the ranger station. Entry is a voluntary donation.

Best for: Hikers who want real jungle without a long drive.

Honest downside: The same source reports occasional robberies on the trail, and it recommends going with a guide. I agree.

4. Jaguar Rescue Center — wildlife rescue up close

This is a working wildlife hospital in Playa Chiquita, not a zoo. The center says it has rescued over 9,000 animals since 2008 and returns about 48% to the wild, and it receives no government funding.

The public tour runs daily at 9:30 a.m. and 11:30 a.m., lasts 1.5 hours and costs $29, with children under 10 free, as of September 2026. You’ll see sloths, monkeys, toucans and snakes, but touching animals is off-limits by Costa Rican law.

Best for: Families and anyone who wants to understand what threatens wildlife here.

Honest downside: You can’t wander on your own, and despite the name, you shouldn’t expect a jaguar. My Jaguar Rescue Center guide explains why.

5. Ara Manzanillo — great green macaws flying free

Great green macaws are huge, loud and rare, and this project in the hills above Manzanillo has been bringing them back. Ara Manzanillo says it has increased the global population of great green macaws by almost 10% and Costa Rica’s by almost 30%.

Visits run 3 to 4 p.m. by reservation only, at $20 for adults with children under 12 free, as of September 2026. Late afternoon is when you’re likely to see the birds, plus toucans, monkeys and sloths.

Best for: Birders and anyone who likes a conservation story with a happy middle chapter.

Honest downside: It’s a one-hour window, and wild birds don’t keep appointments.

6. A chocolate tour — the tastiest history lesson on the coast

A good chocolate tour takes you from the tree to the bar, and this coast has several. Caribeans in Playa Cocles, established in 2007, runs a tour with a forest walk through its cacao, a look at fermenting and drying, and a bean-to-bar tasting.

Tours run at 10 a.m. or 2 p.m. and cost ₡20,000 per person, as of September 2026, daily in high season (January to April) and Monday to Saturday the rest of the year.

Best for: Rainy afternoons, food lovers, kids who need a bribe.

Honest downside: Priced in colones, so the dollar cost moves with the exchange rate.

7. The raptor migration at Kèköldi — a seasonal spectacle

Every fall, a river of hawks and vultures pours over this coast. The Tico Times reports that fall raptor counts at Kèköldi average 2.5 million birds a year, with a record 3 million in fall 2010 and 450,000 in a single day.

The migration runs through September, October and November, peaking in the second half of October. Visits to the observation tower in the Kèköldi Indigenous Reserve are arranged through the Costa Rica Raptor Foundation together with the Kèköldi Wak Ka Koneke Indigenous Association.

Best for: Birders and anyone visiting in October.

Honest downside: It’s seasonal and weather-dependent. Outside the fall window, skip it.

8. The Sloth Sanctuary — the original sloth rescue

The Sloth Sanctuary of Costa Rica began informally in 1992 and was officially authorized as a rescue center in 1997, on the former Aviarios del Caribe property near Cahuita. Its first sloth, Buttercup, lived to 27.

The one-hour Buttercup Tour runs daily, on the hour from 8 a.m. to 3 p.m. (last tour 2 p.m. on Sundays and Mondays), at $30 for adults and $15 for kids 5–12, as of September 2026, with an optional $5 canoe add-on. There’s no touching the sloths.

Best for: Sloth-obsessed kids and adults who want a close look.

Honest downside: It covers a lot of the same ground as the Jaguar Rescue Center, so most people only need one. My guide to seeing sloths compares them.

9. Surf Playa Cocles, or watch Salsa Brava

Puerto Viejo has a real surf culture. Playa Cocles is a long, forgiving beach break and the best beginner spot in Puerto Viejo, while Salsa Brava is a shallow, powerful reef slab for advanced surfers only.

The same source puts the best swell window for this coast between January and March.

Best for: Beginners at Cocles, experts at Salsa, spectators at both.

Honest downside: Salsa Brava is fickle and only comes alive a few times per year. Don’t plan a trip around it.

My surfing guide covers breaks, seasons and safety.

10. Playa Negra, Cahuita — the quiet beach

At the northwest end of Cahuita, Playa Negra is a long black-sand beach flying the Bandera Azul Ecológica, and Lonely Planet calls it Cahuita’s top swimming spot. It’s rarely crowded.

Best for: A slow day that pairs well with a morning in the national park.

Honest downside: Lonely Planet recommends a taxi or a bike with lights at night.

My verdict

If you only do three things on Costa Rica’s southern Caribbean coast, make them Cahuita National Park, a swim at Punta Uva and a refuge hike in Manzanillo. Those three show you the reef, the beach and the jungle, which is the whole point of coming here.

Everything else on this list is excellent. But those three are the backbone, and they cost almost nothing.

Picks for specific situations

Not every trip looks the same, so here’s how I’d reorder the list for a few common cases.

Only one day? Do Cahuita National Park in the morning and swim at Punta Uva in the afternoon.

Traveling with young kids? The Jaguar Rescue Center (under-10s free), Punta Uva’s calm water and the short walk to Miss May Point in Manzanillo.

Rainy morning? A chocolate tour or a rescue center tour. Both run on a schedule and are fun even under clouds.

Serious birder? Ara Manzanillo in the afternoon, and Kèköldi if you’re here between September and November.

Tight budget? Cahuita’s Playa Blanca entrance and the Gandoca-Manzanillo refuge both work on donations, and the beaches are free.

How to plan around the weather

This coast doesn’t follow the Pacific’s dry-season rules, which surprises a lot of first-timers. I break down month-by-month rainfall in my guide to the best time to visit the Caribbean coast, and the bigger differences are in my Caribbean vs Pacific comparison.

A simple rule: do the hikes and tours in the morning, when trails are cooler and animals are more active, and keep afternoons for the beach.

Getting around between activities

Everything on this list sits along one coastal road between Cahuita and Manzanillo, which makes it easy to string activities together. My guide to driving and getting around the Caribbean coast covers bikes, buses and cars.
