This dive site, Tuna Alley, is situated on the western side of the globally renowned Manta Bowl in the Philippines. The dive begins at a depth of 18 meters, characterized by a series of ledges that progressively descend to a maximum depth of 23 meters. The site derives its name from the colossal schools of skipjack tunas that aggregate here, creating a dynamic feeding ground. Navigation typically involves drifting along the reef's contours, observing the rich pelagic activity.
The marine life at Tuna Alley is exceptional, primarily noted for its large pelagic encounters. Divers are almost guaranteed to witness immense schools of skipjack tunas, which in turn attract larger predators. It is a known hotspot for whale sharks, which frequently follow these tuna schools as they traverse the reef. While not explicitly detailed, the reef structure likely supports a variety of smaller reef fish and vibrant coral formations, although the main attraction is undeniably the 'big stuff'.
The best time to experience Tuna Alley generally aligns with the Manta Bowl's peak season, which runs from December to May, when nutrient-rich currents are most prevalent, drawing in the large marine life. Divers should be proficient in drift diving and comfortable with strong currents due to the active pelagic environment. Freedivers with experience can also enjoy this site, taking advantage of the chance to interact with whale sharks and tuna schools on breath-hold. Always consult local dive operators for current conditions and best timing.
