Eil Malk is the largest island in the Mecherchar group of Palau's Rock Islands, a region designated as a UNESCO World Heritage site. Characterized by its porous limestone terrain and dense tropical foliage, the island is home to more than ten marine lakes, which are connected to the surrounding lagoon through ancient fissures and tunnels. The most famous of these is Ongeim'l Tketau, popularly known as Jellyfish Lake. In this isolated environment, millions of golden jellyfish have evolved over thousands of years, losing their ability to sting and allowing visitors to snorkel safely among them. The island is uninhabited, maintaining a pristine natural state, and is accessible only by boat from Koror. Strict conservation measures are in place to protect the delicate biological balance of the lakes. Beyond the jellyfish, Eil Malk's rugged coastline features numerous hidden coves and limestone caves, making it a key destination for eco-tourism and scientific research in Micronesia.
