Verde Island Wall

Batangas City · Batangas · Philippines

Verde Island Wall is the premier wall dive in what scientists have confirmed as the global epicentre of marine biodiversity. Verde Island itself sits in the centre of the Verde Island Passage, the narrow strait between Luzon and Mindoro where a 2005 California Academy of Sciences expedition documented more marine species per unit area than anywhere else on Earth. The southeastern wall of the island drops sheer from a shallow reef crest into the passage's deepest channel, concentrating this extraordinary biodiversity into a single vertical structure. The boat ride from Batangas City takes 45 minutes across the busy shipping lane of the passage. Verde Island rises from the water as a forested hill, its shores fringed by coral reef. On the southeastern face, the reef crest at 3 to 5 metres gives way abruptly to a vertical wall that plunges beyond recreational diving limits into the 200-metre depths of the central channel. Descending over the wall edge, the diversity of life is immediately overwhelming. Hard corals in over 300 documented species create a three-dimensional maze of plates, branches, and massive domes. Sea fans stretch two metres across, their surfaces alive with pygmy seahorses, nudibranchs, and commensal shrimp. Soft corals in every conceivable colour fill the gaps between hard coral colonies, and clouds of anthias in pinks and oranges swarm above every outcrop. The wall's exposure to deep-water currents flowing through the passage brings pelagic visitors that elevate dives from excellent to extraordinary. Devil rays sweep along the wall face in groups of three to seven, their wingspan exceeding three metres. Thresher sharks have been documented at depth, using their elongated tails to stun prey fish against the wall. During full moon tides, hammerhead sharks occasionally appear in the blue water beyond the wall edge. Midway along the wall, overhangs and small caves provide shelter for resting whitetip reef sharks and large groupers. Napoleon wrasse of impressive size patrol the wall with the unhurried confidence of apex reef residents. Schools of big-eye trevally form silvery walls that mirror the rock face behind them. Verde Island Wall demands respect for its currents and depths, but rewards advanced divers with what may be the most biodiverse single wall dive on the planet. Its proximity to Manila, just three hours by road and boat, makes it one of the few world-class wall dives accessible as a day trip from a major capital city.
