Everything you need to know about this dive site.
Dive Site Overview
The waters around Selinog Island hold a compelling blend of natural history and a notable maritime event. This flat tropical island, recognized for its white sand beaches and palm trees, rests atop a significant underwater volcanic structure, shaping its diverse dive terrain.
Below the surface, the reefs here have matured into vibrant ecosystems, supporting a wide array of marine life. A key part of Selinog's diving narrative is the Geopeter wreck, a cargo ferry that sank in 1987. This vessel, now resting between 50 and 65 meters (164 and 213 ft) on a sandy bottom, has transformed into a thriving artificial reef over more than three decades since its incident.
While the island itself is known as an unspoiled, quiet destination, its underwater realm provides an adventurous contrast. Divers find pristine coral formations, intriguing sandy slopes, and even caverns.
The site promises encounters with both minute macro subjects, like nudibranchs and shrimp, alongside larger schooling fish, barracuda, and occasional passing sharks, all contributing to a rich historical and biological tapestry.
