Why dive here
With 428+ marine species recorded in the area - including bull sharks, manta rays, mobula rays (devil rays), seahorses and sea turtles - Twin Cave offers some of Ishigaki & Yaeyama's richest cave diving. Water ranges 23-30°C, warmest July, August, September.
Twin Cave delivers exactly what the name suggests: two swim-throughs that create a fun little maze. It’s a pretty easy dive, even for newer intermediate divers, with a maximum depth of 18m. We usually find plenty of interesting macro critters tucked into the crevices if you take your time. It’s a good option if you’re looking for something a bit different from the standard reef dives.
