This fairylike volcanic lagoon is home to endemic blind albino crabs. You can also find a unique grotto auditorium here and "House of the Volcanoes" - a museum full of interesting exhibitions on volcanos.
Mind that it is forbidden to throw coins into the lagoon as it would affect the environment and hurt the crabs.
