Welcome to Parque Nacional Volcán Poás
In previous years it was possible to peer into the crater, measuring 1.3km across and 300m deep, and watch the steaming, bubbling cauldron belch sulfurous mud and water hundreds of meters into the air. This may be possible again in future, but for now the best place to view Poás is from afar, in the scenic, uncluttered countryside. At research time the volcano was smoking – a spectacular sight. The best time to see it is early in the morning, ideally before the clouds creep in around noon.
