Poas Volcano

During my last week here, I visited two more volcanos—Poas and Irazu. They are both among the mountains that ring the Central Valley, so relatively easy to get to. They also are both in national parks with wide trails leading to overlooks right on the rims of the main craters. Poas's main crater is more than a mile across, and it often sends up steam from the geysers and the lake in that crater. Irazu's last major eruption was in 1963, and it is known for its lake that is distinctively fluorescent green (see below). I feel lucky to have seen the lava flowing down Arenal and now these craters.
