More ways to explore the area's outdoor wonders
The bus climbs out of San José before dawn, headlights carving ribbons through coffee plantations while low clouds cling to the ridges. By the time the road pitches up toward Irazú, the air has thinned and grown noticeably colder; steam-scented pines and scrub replace the wet heat of the central valley. At the summit you step onto a lunar rim—wind pushing and reshaping the angle of view—and the crater sits like an ancient, breathing bowl, rimmed in rust and green.
