Why dive here
With 382+ marine species recorded in the area - including blue sharks, eagle rays, giant moray eels, humpback whales and sperm whales - Grottos offers some of Kadavu & Great Astrolabe Reef's richest cave diving.
The Grottos in Kadavu is a relaxed spot, a good introduction to overhead environments without being too demanding. We like it for newer divers looking to dip a fin into cave diving. You’ll find a series of interconnected caverns, shallow enough that ambient light still filters through, making for some lovely blue hues as you wind your way around. Keep an eye out for sleepy reef sharks tucked into ledges and schooling fusiliers darting through the openings. It’s a comfortable 20-meter max depth, so no decompression worries here, just a gentle exploration.
