Why the Térraba-Sierpe Mangrove is One of Earth’s Greatest Natural Treasures
Formed where the freshwater torrent of the Térraba River converges with the Pacific Ocean, the Térraba-Sierpe National Wetland encompasses over 34,000 hectares of virgin estuarine channels, lagoons, and towering mangrove stands.
Marine Nursery of the Pacific
The dense stilt roots of red and black mangroves shelter juvenile snappers, tarpon, shrimp, and crabs, sustaining fisheries across the Osa Peninsula.
Planet’s Super Carbon Sink
Scientists estimate mangrove forests sequester up to 5 times more organic carbon per hectare than terrestrial tropical rainforests, making your visit part of vital conservation advocacy.
Neotropical Wildlife Corridor
Connects the mountainous interior with Corcovado National Park, providing continuous habitat for endangered tapirs, ocelots, and the endemic Mangrove Hummingbird.
Creatures You Will Encounter in Sierpe
Térraba-Sierpe boasts one of the highest densities of visible wildlife in all of Central America.
American Crocodile
The Térraba-Sierpe wetland is home to one of Central America’s densest populations of American crocodiles. Specimens up to 4–5 meters bask along muddy sandbars during low tide.
Scarlet Macaw
The Osa Peninsula hosts the largest population of Scarlet Macaws in Central America. You will regularly see them flying in loud, affectionate pairs across the mangrove canopy or feeding on beach almond trees.
Three-Toed & Two-Toed Sloths
Both species thrive in the lush cecropia and mangrove canopy along the riverbanks. Expert boat guides spot them resting high in the branches, often with tiny baby sloths clinging to mothers.
Keel-Billed & Chestnut-Mandibled Toucans
With their unmistakable oversized rainbow beaks and vocal hollow calls echoing through the jungle, toucans love perching atop dead trees and palms along the river edges.
White-Faced Capuchin & Howler Monkeys
Troops of intelligent white-faced capuchins comb the mangrove branches for crabs, fruit, and snails, while deep roaring howler monkeys serenade the river at dawn and dusk.
Spectacled Owl & Tropical Raptors
A prize for birders, spectacled owls roost in dense, shaded mangrove hollows. The river is also home to Common Black Hawks, Ospreys, and Yellow-headed Caracaras.
