8 hours (approx.)
Light to moderate fitness — comfortable walking for up to 2 hours and sitting during boat transfer; not technical.
Glide down the Sarapiquí in a private boat, watch monkeys and toucans score the canopy, then cross Tirimbina’s long suspension bridges for a rainforest walk. This full-day from San José pairs calm river wildlife watching with an accessible canopy experience.
The river opens before you like a dark ribbon—water humming under the hull, foliage leaning close enough to read between leaves. On a private two-hour boat safari down the Sarapiquí, howler monkeys announce your passage with a low, rolling chorus while kingfishers flash like punctuation along braided channels. The boat rides low and steady; the guide points out a sunning caiman, a patient iguana on a fallen log, and the occasional sloth, folded into an arm of the canopy.

Wildlife often stays in the canopy or across the river—binoculars dramatically increase sightings.
Sudden showers and river spray are common; a light waterproof shell keeps you comfortable.
Trails are short but can be muddy with exposed roots—rubber-soled hiking shoes are best.
Morning boat departures boost chances of seeing otters, kingfishers, and active monkeys.
The Sarapiquí corridor was historically a transport route and later became a focus for biological research; Tirimbina grew from local conservation and cacao research efforts.
Tirimbina limits visitor access to a portion of the reserve to protect research areas and wildlife corridors; stay on trails and follow guide instructions to reduce impact.
Essential for spotting birds, monkeys, and river reptiles from the boat and bridges.
Quick showers and river spray are frequent—stay dry and comfortable.
summer specific
Provide traction on muddy trails and protection from roots and insects.
Lowland heat makes steady hydration important during the full-day trip.
