Dive Spot Guide•
Cross Hole
Cross Hole is a beginner-friendly Irabu cave dive with dramatic light shafts.
Boat access, a shallow start, and an overhead cave profile make this a light-focused dive; keep buoyancy tidy on a calm day.
About Cross Hole
Cross Hole on Irabu Island is a beginner-friendly cave dive built around a cross-shaped opening that sends shafts of sunlight into a pale sandy chamber. The site starts shallow and drops into a deeper section, with vertical and horizontal passages that make it feel bigger than the numbers suggest. It is the kind of dive where the light is the main event, but fish and macro life add enough interest to make the route worth lingering on.

Scuba Diving
Vertical and horizontal cave passages with a shallow exit around 5 m and a deeper main route; buoyancy control matters more than depth.
Freediving
Not a freedive-first site because the cave passages and deeper route are better handled by scuba.

Snorkelling is not the main draw; the cross-shaped light and cave passages are a scuba experience.
