Clam City
A shallow area in the Rock Islands where giant clams, some over a century old, lie scattered among the coral. It is a classic stop on a full-day snorkeling tour.
Clam City lies north of Ellmers Island (Mecherchar), in the southern Rock Islands where Jellyfish Lake is located. It is about 24 km from Koror, or 30 to 40 minutes by speedboat. The water is 1 to 10 meters deep with almost no current. Dozens of giant clams lie on the seabed, some more than a meter across and reportedly over 100 years old. Their open mantles glow blue, green and purple. Even beginners can snorkel here with ease. It is usually one stop on a Rock Islands island-hopping and snorkeling day trip, alongside Milk Lake and Long Beach, and you stay for about half an hour. A Rock Islands/Jellyfish Lake permit is required (USD 100, valid for 10 days). Do not touch the coral or the clams, and do not stand on them.
