Rumored to have been a huge volcano gradually submerged in a green salt-water lake, the Taal Volcano of Batangas never fails to catch people’s attention whether they get up close and personal with its searing lake or get pretty content admiring its unusual sculpt from afar. Despite posing a tranquil state, it remains one of the deadliest volcanoes in the world—an ideal retreat for daredevils and wanderers.
