The Térraba-Sierpe wetland

The Térraba-Sierpe National Wetland protects the largest mangrove forest in Costa Rica, listed as a wetland of international importance (Ramsar). Its tangled roots are a nursery for fish and crustaceans and a refuge for wildlife.

  • 🐊 American crocodiles and caimans,
  • 🐒 capuchin monkeys and sloths,
  • 🪶 herons, egrets, kingfishers and raptors,
  • 🦎 iguanas and basilisks, sometimes snakes in the branches.

Boat or kayak?

By boat from Sierpe: a relaxed 3-hour ride with a guide explaining everything. Ideal for families and photographers.

By kayak from Coronado (10 minutes from Ojochal): you paddle a double kayak with a local Boruca guide, in silence. More immersive, away from the crowds.

Tips

  • Go in the morning: animals are more active and it is cooler.
  • Bug spray, hat and sunscreen are a must.
  • Binoculars and a camera with a zoom make a big difference.
  • Sierpe is also where boats leave for Drake Bay: easy to combine with your travel day.

Frequently asked questions

Are there crocodiles in the Sierpe mangroves?

Yes, American crocodiles are common and are watched from the boat at a safe distance.

How long is the mangrove tour?
