@SchrodySweden well u shoud.. It's really cool.. U not allowed to wear fins when swimming in the lake.. I went the one located in borneo/ kalimantan island (kakaban lake, derawan island), others are in sulawesi and west papua islands.. Not only see jellyfish u also can see a lot of sea turtles from big to the small one.. http://www.indonesia.travel/de/en/destinations/kalimantan/derawan-archipelago/maratua-island
