Peleliu Express - Peleliu & Angaur
The Blue Cave, tucked along the coastline, offers a unique cavern dive experience. Sunlight filters through an opening, painting the water a vivid electric blue inside the main chamber. It’s a relatively easy penetration, making it a good option for divers looking for their first taste of overhead environments without extreme depths. Look for the small, reflective particles that shimmer in the blue light, a simple but captivating sight.
