About Thumba Caves
Thumba Caves is on the north wall of Thumba Island and features a vertical wall with multiple caves. The caves sit around 20–25 m, creating a channel-style dive where current can be noticeable. The caves host macro life such as moray eels, shrimp, glassfish and nudibranchs, while pelagics like eagle rays, tuna and whitetip reef sharks may pass by along the wall.
