More ways to explore the area's outdoor wonders
Dawn in Puerto Jiménez tastes of diesel and thick rainforest air. Guides meet before first light, and a shared transfer deposits you at Carate Beach where the trail swallows the coast and the jungle presses close. Footsteps quickly vanish under a canopy that shifts from bright bromeliads to dark, dripping understory; at night the forest takes on a different voice—rustling, insect choruses, and distant calls from nocturnal mammals.
