8 Iconic Spots – WWII Wrecks & Stunning Limestone Caves
Palau is a true paradise for divers. While its offshore sites like Blue Corner are world-famous, the waters near Koror hide a collection of equally mesmerizing treasures. From haunting WWII shipwrecks to the enchanting stalactite formations of Chandelier Cave, these nearshore dives combine history, geology, and marine life into unforgettable underwater experiences.
This guide highlights 8 must-visit nearshore dive sites, offering something for wreck enthusiasts, cave explorers, and reef lovers alike.
Chandelier Cave
Depth: 5–15m | Visibility: up to 30m | Current: None | Recommended: OW (good buoyancy required)
A Palau signature dive, Chandelier Cave is a natural limestone cavern with multiple air chambers. Divers ascend into air pockets, inflate their BCDs, and even chat briefly without regulators—a surreal experience. Inside, you’ll discover dramatic stalactites and crystal formations, perfect for light-beam photography.Outside the cave, keep an eye out for the elusive mandarinfish (often called “emperor’s robe fish”), with its vibrant blue and orange markings.
Buoy #6 Wreck
Depth: 3–27m | Visibility: 5–18m | Current: Mild to Strong | Recommended: AOW
Located in Malakal Channel, this WWII Japanese wreck rests at 22–24m and is draped in soft corals. Barracuda schools, snappers, reef sharks, and turtles frequent the site. Strong currents during tide shifts make this an exciting drift combined with wreck exploration.
IRO Maru Wreck
Depth: Deck 25–28m / Max 40m | Visibility: 10–30m | Current: Minimal | Recommended: AOW + Nitrox
The most famous wreck in Palau, the IRO Maru (143m long) was sunk in 1944. Divers can explore its massive deck, anti-aircraft guns, and open corridors (penetration for trained divers only). Covered in coral and teeming with clownfish, groupers, and turtles, it’s both a living reef and a haunting WWII relic.

Helmet Wreck
Depth: 15–35m | Visibility: 5–20m | Current: None | Recommended: AOW + Nitrox
