You step off the skiff into a humid breath of rainforest: the water pulls away and the trail ahead is a ribbon of packed soil, roots and the distant call of howler monkeys. On day one you move inland to Sirena Station in Corcovado National Park — a remote ranger outpost where primary forest presses against the trail and every bend can reveal tapirs, scarlet macaws or a sloth tucked in a shoulder-high cecropia tree. On day two the Pacific reclaims the view as a short boat ride delivers you to Caño Island’s clear shallows, where turtles and colorful reef fish glide through swaying coral and currents nudge you along.
moderate.
2 days (approx).
Moderate fitness: able to hike 5 hours on uneven, sometimes muddy terrain and swim/snorkel for up to 2 hours total.
Most travelers overnight in Drake Bay; boats depart from the town dock—confirm your exact pickup with the operator as some transfers originate from nearby lodges.
The hike involves uneven terrain and several hours on your feet; older adults and children may participate if reasonably mobile, but consult the operator about pace and assistance.
Yes—guided snorkeling areas are chosen for visibility and moderate conditions; basic comfort in the water and the ability to float are required.
Expect monkeys (howler, capuchin), sloths, various toucans and macaws, and possibly tapirs or peccaries—sightings vary by season and time of day.
Corcovado was set aside as national park in 1975 to protect one of Central America's last large tracts of primary rainforest; Sirena Station became a focal point for long-distance biological surveys.
Both Corcovado and Caño Island are protected areas—follow guide instructions, avoid touching coral, and use reef‑safe products to minimize impact.
