Eil Malk
Island Palauan island hosting the famous Jellyfish Lake
Eil Malk in Palau contains the famous jellyfish lake (Ongeim’l Tketau) used for guided snorkeling with non‑stinging jellyfish, and surrounding lagoons that draw divers to the Rock Islands.
Eil Malk is an island in the Rock Islands group of Palau’s Koror State, noted for containing a distinctive marine lake known internationally as Jellyfish Lake. The island and its lake are part of the Rock Islands Southern Lagoon, inscribed as a UNESCO World Heritage Site.
The island’s primary highlight is the lake, where millions of golden jellyfish live in a stratified marine lake and where guided snorkeling is the usual visitor activity. The lake’s ecological conditions and the jellyfish population make it one of the most visited natural attractions in the Rock Islands.
The lake and island have been used traditionally by local communities and more recently have been managed for conservation and tourism. The Rock Islands and their lagoons are protected for their biodiversity and cultural values.
Eil Malk lies within Palau’s Rock Islands in Koror State, among a dense cluster of limestone islets and sheltered lagoons in the western Pacific.
