More ways to explore the area's outdoor wonders
Fog parts above the road and the air cools — you climb out of the Central Valley into a lane of orchids and coffee terraces. By the time the visitor center appears, the volcano’s rim breathes steam: a shallow, steaming crater ringed by black rock and cloud forest. Visitors stand at the official overlook and watch the crater pool glimmer, with fumaroles spitting sulfur-scented steam that dares you closer while keeping a safe distance.
