Rock Island

Scubago lists Rock Island as a dive site in Siargao.

Rock Island and Stimpy’s have separate dive-site pages and are both named in an Ocean Tribe dive offer. Their nearby surf-break names do not identify a safe dive entry or navigation point.

Location unresolved: No source coordinate has been admitted for this partial guide. It has no map marker or navigation point.

Depth, current strength, visibility, seasonal conditions, access arrangements and diver suitability remain unknown in this partial guide. Confirm the intended site and a suitable dive plan with a local operator. No local-diver verification has been recorded.

What the SSI listing describes

The SSI/Scubago dive-site page for Rock Island, maintained for Ocean Tribe Siargao, describes a coral reef adjacent to Rock Island between 3 and 10 metres, dropping to a sandy slope that goes down to 25 metres in the channel between the surf spots of Rock Island and Stimpy's, and says visibility generally ranges between 10 and 25 metres year-round. It lists fields of cabbage corals with stingrays, rabbitfish, squirrelfish, butterflyfish and triggerfish as resident reef fish, and nudibranchs, cuttlefish and reef octopus. Ocean Tribe's own two-boat-dive offer on the same platform covers Stimpy's, Rock Island, Semi Bayan and Boomies as sites 5 to 15 minutes from shore, with visibility of 15 to 25 metres, depths of 10 to 15 metres, and stingray, cuttlefish and reef fish to see. The site page and the offer are one operator lineage and differ on the figures (3 to 25 metres against 10 to 15 metres for depth; 10 to 25 against 15 to 25 metres for visibility); they are not reconciled here and neither is recorded as a verified site range.

Where other pages place the island

Two pages written about Blue Cathedral rather than this site locate the island itself: Zentacle describes the Blue Cathedral dive as sitting behind "a small rock named Rock Island" in front of the Cloud 9 surf spot, and UW360's article of 12 May 2022 calls Rock Island one of Siargao's tiny outlying islands near that site, reachable by boat from General Luna in under half an hour. Neither gives a coordinate for the Rock Island dive, so the location remains unresolved here.
