This dive site, Baluarte, located along the western coast of Apo Island, offers a unique insight into the island's geological past. Divers are treated to an unusual phenomenon where a continuous stream of bubbles, indicative of volcanic activity, seeps from the seafloor. The site is characterized by massive coral bommies scattered across the reef, providing diverse habitats. Navigation often involves following the reef contour, with garden eels facing the mild currents at the bottom.
The marine biodiversity here is rich, featuring numerous forms of reef fish concealed within the large coral structures. Notably, the site is a thriving habitat for graceful sea snakes and majestic green turtles. Garden eels are a common sight, swaying with the current on the sandy bottom, while the vibrant corals add to the visual spectacle.
The best time to visit Baluarte, like most of the Philippines, is during the dry season from October to May, when water conditions are typically calm and visibility is excellent. This site is highly recommended for both scuba divers and freedivers due to its manageable depths and abundant marine life. Snorkelers can also enjoy the shallower areas near the surface, observing the unique bubble activity and marine inhabitants.
