Rock Islands Southern Lagoon
Koror
The Rock Islands Southern Lagoon, also locally known as Chelbacheb, consists of 250 to 300 small limestone and coral islands located between Koror and Peleliu in Palau. These islands, formed about 40 million years ago during the late Eocene, feature distinctive mushroom-like shapes caused by erosion and marine life activity. The area is renowned for its pristine beaches, crystal-clear blue lagoons, and exceptional marine biodiversity including unique stingless jellyfish found in Jellyfish Lake. The islands hold deep cultural and spiritual significance for indigenous Palauans, with many oral traditions and beliefs tied to them. The Rock Islands also have historical importance, having been sighted by European explorers in the 16th century and fortified during World War II. Today, the area is a popular destination for diving, snorkeling, and eco-tourism, featuring sites like Blue Corner, German Channel, and Dolphin Bay, where visitors can learn about local marine life and conservation efforts. The islands' sparse population includes the only inhabited area at Dolphin Bay, which serves as Palau’s national aquatics park and ranger headquarters.

Historia
The Rock Islands formed during the late Eocene period around 40 million years ago through coral reef limestone accumulation and volcanic shaping.
Early settlers arrived circa 1000 BC, likely from Southeast Asia or the Philippines, establishing cultural connections that continue today.
European contact began in the 16th century with Spanish explorers, and the islands saw military significance during World War II when Japanese forces fortified them.
Post-war, the islands were preserved under U.S.
administration and later designated a UNESCO World Heritage Site in 2012 for their ecological and cultural importance.
