Romblon dive sites

Banton Island is one of the most remote inhabited islands in the Romblon group. A small ferry connects Banton to Romblon Town several times per week, with the crossing taking approximately three to four hours depending on sea conditions. From Manila, Romblon is reached by ferry from Batangas port or by small aircraft to Tablas Island followed by a boat transfer. There are no dive operators on Banton itself, so diving must be arranged from Romblon Town with operators willing to make the journey, or by private boat charter.

Banton Island sits on the edge of the Sibuyan Sea, one of the deepest inland seas in the Philippines with depths exceeding 2000 metres. The island's volcanic geology creates sheer underwater walls that drop almost vertically from shallow reef platforms into this abyss. The walls face open deep water, which brings nutrient-rich currents and pelagic visitors that shallower reef environments rarely attract. The combination of wall structure, deep water access, and zero fishing pressure from recreational diving creates conditions comparable to famous wall dives like Sipadan's drop-off.

Accommodation on Banton is extremely limited and basic. A few family-run guesthouses offer simple rooms, and homestay arrangements can be made through the barangay offices. There are no resort-level accommodations and no reliable internet connectivity. Visitors should bring sufficient supplies and be prepared for genuine off-grid living. Most divers exploring Banton base themselves in Romblon Town, where several small hotels and dive operations offer more comfortable facilities, and make day trips to Banton when weather permits.

Batad Island is accessed from Romblon Town on Romblon Island, reached by ferry from Batangas port or by small aircraft to Tablas Island with onward ferry. Local dive operators in Romblon Town provide boat trips to Batad Island, approximately 20 to 30 minutes away. The diving infrastructure in Romblon is small-scale and advance booking with operators is recommended.

Romblon province sits at the crossroads of several Philippine sea basins, receiving currents that bring planktonic nudibranch larvae from diverse source populations. The healthy reef substrate provides abundant food sources for nudibranchs in the form of sponges, hydroids, and bryozoans. Low diver impact means populations remain undisturbed. Scientific surveys have documented over 200 species around Romblon's islands, making it one of the top nudibranch diversity hotspots globally.
