Introduction

Volcán Poás National Park lies in central Costa Rica around a still-active volcano, its best-known feature a vast crater lake. The crater is wide, and the lake's colour shifts with volcanic activity and weather, turning blue-green on clear days, while fumaroles and sulphur features line the rim. At high altitude and with abundant moisture, vegetation is mainly elfin forest and highland meadow, and the weather is changeable — cloud can roll in and block the view without warning. The trails are short, but volcanic activity can temporarily change which areas are open, so confirm conditions before you go and prepare for cold and rain.
