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.

Corcovado is part of the geologically young Osa Peninsula; uplift and volcanic activity over millennia created steep river valleys and rich soils that sustain unusually high biodiversity. The area’s cultural history includes long-standing indigenous presence and later conservation efforts—Sirena’s station exists because of sustained national and local protection. Local guides combine natural history with practical route sense, reading recent trail conditions and tide tables the way a captain reads the wind.
Practical guidance: expect strenuous but steady hiking around 5 hours on uneven, muddy trails and a full day of snorkeling with two guided swims. Bring reef‑safe sunscreen, quick‑dry clothing, sturdy shoes with grip, and a waterproof bag for camera gear. Start early to avoid afternoon rain and maximize wildlife sightings; respect park rules and keep distance from animals. With common-sense prep, this two-day pairing delivers rainforest intensity and Pacific clarity in equal measure.
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.
