An short and easy hike to an active volcano

Hazards and warnings

might be cold - and an eruption is always possible (but then the park will be closed).

Detailed description

Volcano Poas had it's last major eruption 1952-54 and currently emits smoke only (smelling a bit rotten eggs). The outer crater has 1.5 kms in diameter (supposedly the second largest crater in the world), the inner crater has a diameter of some 300m and is filled with Laguna Caliente - which is perhaps the worlds most acid lake with a ph of 0.

As the volcano is covered by clouds nearly every day starting at around 10am, it is strongly advised to go there using your own car - as both the public bus and most tour buses arrive at 10:30am - with potentially no view of the volcano...
