White Caves – South Coast

Site Overview

White Caves features a series of limestone caverns along the South Coast of Christmas Island where resident whitetip reef sharks rest on the sandy bottoms creating one of the most reliable shark encounter sites on the island. The cave system has been carved into the limestone cliffs by thousands of years of wave action creating spacious passages and chambers with multiple entrances that allow comfortable exploration by recreational divers. Inside the caves, whitetip reef sharks are regularly found resting in groups on the sandy floor where they seek shelter from the currents and sunlight during the day. Schools of glassfish shimmer in the torch beams while soldierfish and squirrelfish occupy the darker recesses of the cave system. Lobsters are common throughout the cave passages hiding in crevices and beneath rock ledges during daylight hours. The cave walls support encrusting organisms including sponges, bryozoans, and soft corals that add colour and biological interest to the geological formations. Light filtering through cracks and openings in the limestone ceiling creates atmospheric pools of illumination that enhance the cavern diving experience. The combination of reliable shark encounters, atmospheric cave exploration, and diverse cave-adapted marine communities makes White Caves one of the most exciting and memorable dive sites on the South Coast offering a thrilling introduction to cavern diving for appropriately certified recreational divers.
