Jellyfish Lake

Eil Malk Island (Rock Islands), Palau

---

Jellyfish Lake, located on Eil Malk Island in the Rock Islands of Palau, is one of the country’s most famous natural attractions.

This unique marine lake is home to thousands to millions of golden jellyfish that have evolved in isolation and are largely harmless to humans, allowing visitors to snorkel among them. The lake is connected to the ocean through small fissures and tunnels in the surrounding limestone, but it remains isolated enough to have developed its own distinct ecosystem.

The jellyfish migrate across the lake each day, creating a remarkable natural spectacle in the calm, clear waters. Surrounded by lush tropical forest and dramatic limestone islands, Jellyfish Lake offers a rare wildlife experience found almost nowhere else in the world. Its unusual ecology, stunning setting, and scientific importance make it one of the most iconic destinations in Palau.
