Laguna Caliente
Laguna Caliente, found in Costa Rica, can be directly translated to “hot lagoon.” The reason this lagoon gets this name is because it is quite hot, like volcanic level hot. Its location in the middle of a stratovolcano means that a human could not survive a dip in this lagoon. In fact, visitors need a special permit just to traverse the areas around the lake.
