Backpacking in Gandoca-Manzanillo Wildlife Refuge
👌 Worth visitingnational park ranked #15
By Johan Kruseman 🇳🇱 | Updated October 22, 2026

I was rinsing sand off my boots at the Manzanillo trailhead when howler monkeys started up, a low roar rolling through wet almond trees, and I was glad I had brought my own water and snacks, since the village shops are small and priced for captive hikers. Gandoca-Manzanillo Wildlife Refuge sits on the Caribbean coast of southeastern Costa Rica, southeast of Puerto Viejo. The coastal trail is flat, muddy and gorgeous, with sloths, crabs and quiet beaches, though rain is constant and the gravel road is slow. Carry small bills and book guides ahead for night turtle walks.

✨ Why go?
Ranked #15 national park in Costa Rica
What makes this national park worth exploring

Gandoca-Manzanillo Wildlife Refuge suits travelers who like to walk with a rucksack and no schedule. The coastal trail from Manzanillo toward Punta Mona follows the shoreline through forest, with no entry gate or tour required, so you set the pace and swim where the beach looks inviting. Wildlife is the other draw: leatherback, green and hawksbill turtles nest on the beaches at different times of year, and community-run guides in Gandoca take small groups out at night, which makes the experience far more personal than the crowded turtle spots elsewhere. The villages are tiny, the reef is close, and the whole area feels remote even though Puerto Viejo is nearby.

💡 HighlightsTop highlights of Gandoca-Manzanillo Wildlife Refuge

  1. Punta Uva to Manzanillo coastal trail: The refuge’s signature walk runs along the shore past coconut palms and driftwood, with monkeys overhead and hermit crabs underfoot.
  2. Punta Mona: The far southeastern point at the end of the trail, reached on foot or by boat, with a rocky shoreline and dense forest behind it.
  3. Gandoca Beach turtle nesting: Leatherbacks come ashore in the early months of the year, while other species nest later, and guided night walks help protect the nests.
  4. Gandoca Lagoon: A mangrove-fringed estuary where caimans, herons and kingfishers are common, best explored by boat with a local guide.
  5. Manzanillo Beach: A long strip of pale sand with calm stretches for swimming and a small village behind it with simple eateries.

  6. Orchid and wetland forest: The Orey wetland, the only one in the country with a native orey tree forest, is home to caimans, manatees and many birds.
  7. Coral reef snorkeling: Offshore reefs, among the best on Costa Rica’s Caribbean coast, can be snorkeled from Manzanillo when seas are calm.
Gandoca-Manzanillo Wildlife Refuge is best met first on the Manzanillo coastal trail, since it gives you forest, wildlife and beach in a single easy walk.

🌤️ When to go?Choosing the right time of year

The southern Caribbean coast has its driest stretches in September and October and again in February and March, the reverse of the rest of Costa Rica.
  • Sept to Oct: Calmest sea, clearest water for snorkeling at Punta Uva and Manzanillo, and thinner crowds. Days run 26 to 31°C (79 to 88°F).
  • Feb to Mar: Another dry window, with busier trails and higher lodging prices around Puerto Viejo.
  • Leatherback nesting, March to July: Gandoca beach patrols run on dark nights, so volunteer programs fill early.
  • Nov to Jan and Apr to Aug: Rain can arrive any week, with 24 to 30°C (75 to 86°F) and rougher surf.
Book December and Easter beds weeks ahead, and expect roughly 12 hours of daylight all year.

🛏️ Where to stay?Where staying makes the most sense

No regular lodging exists inside Gandoca-Manzanillo Wildlife Refuge, so most backpackers sleep in Puerto Viejo de Talamanca, 13 km (8 miles) west of Manzanillo village. Puerto Viejo has the widest choice: dorm beds at US$10 to 18, private rooms from US$30, plus bars, bike rental and buses to Manzanillo. Playa Cocles and Punta Uva, along the coast road, suit quieter stays in jungle cabinas at US$35 to 70. Manzanillo village sits at the refuge edge and has a few simple guesthouses and cabins at US$25 to 60, which puts you at the trailhead and beach by morning.

  • Manzanillo beach walk: A short, easy stroll of under an hour along the sand, good for swimming and watching birds.
  • Gandoca Lagoon route: Mostly done by boat with a guide, about 2 to 3 hours, passing mangroves and wetlands where caimans and wading birds live.
  • Gandoca night turtle walks: About 2 to 3 hours on dark beach with a local guide, easy but best done with a red light and closed shoes.
Wear quick-drying shoes and carry water and insect repellent. Buses and shared taxis run from Puerto Viejo to Manzanillo, and Gandoca is reached by a rougher road. Crowds are light, mostly day visitors in Manzanillo. Walking the coastal trail is free, while guided tours and the Gandoca turtle program charge a fee.
⚠️ Hiking info can sometimes be outdated or inaccurate. Before you hit the trail, check the latest conditions with locals. If you do spot anything that's off, I'd love to hear from you, so I can update it for fellow travelers.

🛡️ SafetyScams, Hazards, and Annoyances

Gandoca-Manzanillo Wildlife Refuge is straightforward, but the coastal trail from Manzanillo to Punta Mona turns muddy and slippery after rain, so wear shoes with grip and carry water. River mouths swell fast, and Gandoca’s crossings can be impassable after heavy rain. Rip currents hit Manzanillo and Punta Uva, so swim only where locals do. Snakes (including the venomous fer-de-lance) and poison dart frogs live on the forest floor, so watch where you step and never touch. Sea turtle nesting beaches are closed to unguided night visits, and flashlights are discouraged. Bring insect repellent and keep valuables out of sight at beaches.

We 💚 feedbackKey takeaways before you go

Gandoca-Manzanillo Wildlife Refuge is often rushed as a half-day detour from Puerto Viejo, which means missing the best part. I would sleep nearby, walk to Punta Mona early with proper shoes, and join a local-guided turtle walk at night rather than wandering the beach alone.
