The Republic of Palau is an archipelago located in the western Pacific Ocean. While it may be small, this island nation is a true paradise for travelers seeking adventure. One of Palau’s most famous attractions are its jellyfish lakes, where swimmers can take a dip alongside thousands of harmless jellyfish. The largest concentration of jellyfish can be found in Jellyfish Lake on Eil Malk Island. This unique lake is home to millions of golden jellyfish, making it the perfect place to have an up-close and personal encounter with these amazing creatures.

Jellyfish Lake is one of the 12 saltwater lakes scattered across the islands of Eil Malk and Ngeaur in Palau. It was formed over 12,000 years ago when two limestone caves were sealed off by volcanic activity, trapping the lake’s inhabitants inside. Scientists believe that these jellyfish are descendants of their open-ocean relatives who adapted to their new environment over time. Today, there are around seven million jellyfish living in this lake.

The golden-brown jellyfish here range from dime-sized to dinner plate-sized, but they won’t sting you as they have lost their stinging cells due to the lack of predators in the lake. You’ll have plenty of time to observe and photograph these fascinating creatures as you swim alongside them from one end of the lake to the other. Jellyfish Lake is connected to the Pacific Ocean via an underground cave system, but over time it has become completely enclosed and isolated from the ocean. For this reason, the species of jellyfish found in this lake have been evolving independently for thousands of years, and are now unique to this location.

Aside from swimming with jellyfish, there are many other activities you can enjoy while visiting Eil Malk Island. The island is surrounded by white sand beaches where visitors can relax during low tide or take part in exciting water sports such as kayaking or snorkeling when the tide is high. Furthermore, exploring the nearby caves is another great way to spend your day on Eil Malk Island – just watch out for bats. You will also find plenty of WWII relics scattered around the island which provide insights into its fascinating history.
