Corcovado National Park, Osa Peninsula · Costa Rica
National Geographic once called the Osa Peninsula the most biologically intense place on earth, and a dawn walk out of Sirena station makes the case: a Baird's tapir asleep in the shade behind the ranger buildings, scarlet macaws shrieking through the beach almonds, spider monkeys overhead and fresh puma tracks stitched along the tideline. Corcovado is Central America's last big block of Pacific lowland rainforest, and it is walked, not driven. The rules shape the trip: entry only with a licensed local guide, daily visitor caps, and permits that sell out weeks ahead in the December–April dry season. Most people boat in from Drake Bay (spinner dolphins en route are a bonus) or approach from Puerto Jiménez via Carate; an overnight in the Sirena dormitory doubles your wildlife hours. The variable that flattens visitors is heat — 90 per cent humidity by 8am — so starts are pre-dawn, water is carried in litres, and the midday hours belong to the hammock. Four days from Drake Bay with guide, permits, boats, dorm night and meals runs about £600–£800. Swimming at river mouths is off the menu: bull sharks and crocodiles patrol them.
