Dive Spot Guide•
Tunnel
Advanced tunnel dive with a cavern and rocky critter exit.
Boat dive with a shallow entrance tunnel, a central cavern, and a tighter exit into rocky terrain. Best for experienced divers with a torch and solid buoyancy.
About Tunnel
Tunnel is an advanced boat dive built around a short underwater tunnel and a central cavern, followed by a rocky exit zone with small reef life and critters. It suits divers who want an overhead route with a torch, solid buoyancy, and a dramatic light-and-shadow passage rather than a simple reef swim. It rewards calm pacing and careful trim.
