Caves and caverns of Cebu and Coron

Cathedral Cave (Coron Island)

  • Max depth30 m
  • CertificationFull cave

The dive

Below a cliff on the south side of Coron Island you sink through a narrow well in the rock and swim through a short tunnel into a large chamber, where the light from outside plays in the clear water.

Only in calm weather and quiet tides: in bad weather an unpredictably strong surge runs through the tunnel that can cause serious injury.
Sangat asks for a cave diver certification (and Advanced); Pirates names Advanced Open Water for experienced divers, Zentacle 'intermediate'. We plan with the strictest: dive the tunnel and the air chamber only with cave training or with a dive centre that admits you itself.
Profile and sections

Below a cliff on the south side of Coron Island you sink through a narrow well in the rock and swim through a short tunnel into a large chamber, where the light from outside plays in the clear water. Behind the chamber a short passage leads to a small chamber with air.

Practical: Sangat Island Dive Resort and Pirates Diving Center go there, only in calm weather.

Depth and profile
To 30 m (Pirates, Zentacle); Sangat gives 8 m in the cave itself. First 6 m down through the well, then a tunnel of 12 m (Sangat) to 20 m (Zentacle) into a large chamber.
Configuration
Short tunnel into a large chamber: recreational gear with a torch; a fixed line is sometimes in place (estimate).

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.

How to get there

By boat to the southern tip of Coron Island, about 45 minutes from Sangat. The entrance is a near-vertical well in the rock below a cliff.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): Scotty's Action Sports Network's pages on Pawod and Marigondon, Filipino Cave Divers on the Pawod cave system (2013) and their 2017 warning, the PADI Travel page of 7 Seas Aquanauts, Kasai Village's own page (2019) and its SSI listing, the dive-site pages of Sangat Island Dive Resort and Pirates Diving Center in Coron, Zentacle, Wikipedia (Coron Island, Coron, Mactan Shrine), the chamber list of divephilippines.com.ph (undated), Cebu Daily News (2019) and divers.ph (2024) on the chambers. Savedra in Moalboal no longer offers cave diving; its caves without another dive centre (Casili, Tuble, Saavedra Cave) are therefore left out. No source gives coordinates for the caves. Certification and configurations are partly estimates.
