Located on Eil Malk Island, this marine lake is home to millions of harmless golden jellyfish. Over thousands of years, these jellyfish have lost their ability to sting, allowing visitors to snorkel among them. The lake is part of Palau’s delicate ecosystem; while swimming is permitted, authorities strictly prohibit diving to protect the jellyfish. This surreal encounter with gentle, pulsating jellyfish is something you should not miss.
