Volcanoes do no let us go here in Nicaragua. However, the next one on our trip had already exploded 23,000 years ago, creating the Laguna de Apoyo, a crater lake with a diameter of more than 6 kilometers and a depth of around 200 meters. The water temperature is a constant 27 degrees, thanks to the thermal springs that heat the lake in various places. Not that we needed warm water, quite the opposite. Cold water to cool off was more on our wish list. Despite the temperatures, doing nothing was of course out of the question.
