Easy Rarotonga reef with lava-tube swim-throughs
Boat handling and careful buoyancy through the tunnels are the practical way to dive it.
Sunset Lava Tubes is an easy overhead reef on a broad coral shelf above west-coast Rarotonga, with lava tunnels, swim-throughs, and shallow exit points that make it a fun second-dive profile. It suits divers who want relaxed structure, small marine life, and a little cavern character rather than a high-current pass or deep wall. The site rewards tidy buoyancy through the tubes and a calm, controlled pace.
