Banton Island

Romblon Town · Romblon · Philippines

Banton Island rises from the Sibuyan Sea like a fortress, its volcanic cliffs standing guard over some of the deepest water in the Philippine archipelago. The Sibuyan Sea reaches depths exceeding two thousand metres, and Banton sits on its eastern edge, the island's underwater walls dropping with vertiginous directness from shallow reef into blue-black abyss. No dive operation has established itself on Banton. No resort caters to visiting divers. The island exists in a state of marine preservation that the Philippines' popular dive destinations abandoned years ago. The western wall is the signature dive. The reef crest begins at five metres, a narrow platform of hard coral growth that abruptly terminates at a vertical face. The wall drops sheer, decorated with black coral trees, enormous gorgonian fans, and barrel sponges that cling to the volcanic rock in defiance of the current. At thirty metres, overhangs create sheltered chambers where whitetip reef sharks rest in rows, their bodies gently swaying with each surge. I drifted along the western face on a rising current that pushed plankton against the wall, triggering a feeding cascade visible at every depth. Schools of fusiliers formed silver curtains in the blue water, pursued by giant trevally hunting with explosive speed. A chevron barracuda school held formation at the wall edge, hundreds strong, their disciplined geometry disrupted only by the passage of a large Napoleon wrasse shouldering through. The pelagic encounters are what set Banton apart from Romblon's better-known sites. The deep water offshore channels the Sibuyan Sea's currents past the island, and on good days the blue beyond the wall reveals silhouettes: hammerhead sharks cruising at the edge of visibility, thresher sharks with their elongated tails unmistakable even at distance. These encounters are not guaranteed but they are regular enough that the handful of divers who know Banton return repeatedly.
