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.

Community notes to help plan your visit.

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.

Snorkeling

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