You push off from Drake Bay as morning light slices the Pacific; the boat nose parts small waves and the forest on the Osa Peninsula leans toward the water as if listening. An hour and a half later you step onto the narrow beach at Sirena Biological Station, where the jungle immediately closes in—humid, green, loud with insect and bird calls.

Corcovado National Park, established in 1975, occupies one of Central America’s most intact lowland rainforests. Geologically the park is a coastal plain backed by ancient volcanic ridges; trails cross ridged soil, river crossings, and flat alluvial floodplains that change mood with the rains. Local communities around Drake Bay have fished and farmed for generations and now share guiding knowledge rooted in both modern science and lived experience.
The overnight itinerary centers on two full days of guided hikes: a long morning loop, a relaxed afternoon swim in the Claro River, a midnight-to-dawn patrol-style walk for nocturnal wildlife, and early-morning searches for tapirs, scarlet macaws and howler monkeys. Rangers manage a simple sleeping area with blankets and basic facilities; lights are out early and the forest keeps its own schedule.
Practical notes: bring a sturdy pair of waterproof hiking shoes, waterproof layers and insect protection; expect muddy, rooty trails and several stream crossings. Hydrate often, pack a daypack for two hikes per day, and be prepared for limited phone signal. Permits, an experienced guide, and reef-safe sunscreen are standard; the park’s strict rules protect its wildlife, and moving quietly is part of the experience. This is an immersive, physically moderate overnight for travelers ready to trade comfort for close encounters with one of Costa Rica’s wildest places.

Corcovado National Park was established in 1975 to protect one of Costa Rica’s last stretches of undisturbed lowland rainforest and the coastal ecosystems of the Osa Peninsula.
