Dive profile & how the dive runs

Dives at Tongo Sanctuary typically begin with a boat entry, often combined with trips to nearby sites like Pescador Island. Upon descending, divers immediately encounter a steep wall that extends from 5 meters down to 55 meters. The route generally follows the contours of this wall, allowing for exploration of the vibrant hard and soft coral formations and smaller caves embedded in its structure. Depth progression can be tailored to diver certification, with shallower sections offering ample marine life for Open Water divers. Turning points are usually determined by air consumption and planned bottom time, often involving a gradual ascent along the wall. The safety stop is commonly conducted in the shallower sections of the reef, around 5 meters, where divers can enjoy the reef top's bustling activity before surfacing.

Underwater photography

Tongo Sanctuary provides excellent opportunities for both wide-angle and macro photography, thanks to its vibrant wall and diverse inhabitants. For wide-angle shots, a fisheye or wide-angle lens is ideal to capture the expansive coral formations, the steep drop-off, and any schooling fish or pelagics. Macro photographers will thrive on the wall and in its crevices, where nudibranchs, ghost pipefish, and electric clams can be found. Careful buoyancy control is essential to avoid disturbing the delicate corals and silting the bottom, especially near the wall. External strobes are recommended to bring out the true colors of the corals and marine life, particularly in deeper sections. When photographing wildlife, maintain a respectful distance and avoid harassing subjects to ensure their natural behavior.

Getting there & logistics

Tongo Sanctuary is primarily accessed from Moalboal, Cebu. Divers typically fly into Mactan-Cebu International Airport (CEB), then take a land transfer to Moalboal, which can take approximately 2-3 hours. Most dive operators in Moalboal offer day trips to Tongo Sanctuary, often combining it with other nearby sites like Pescador Island as part of a two-tank dive package. Trips are usually conducted by local dive boats, with a short travel time to the site. Marine park fees may apply as it is a protected area, usually included in dive package costs. Liveaboards operating in the Visayas region might also include Moalboal in their itineraries, though day boat trips from Moalboal are the most common way to dive Tongo Sanctuary.

Safety & environment

While Tongo Sanctuary is suitable for all levels due to minimal currents, divers should always adhere to standard safety protocols. Ensure your dive insurance is current and covers diving in the Philippines, including emergency medical evacuation. The nearest recompression chamber is typically located in Cebu City, which entails a significant land transfer from Moalboal. Divers should maintain good buoyancy control, especially on the steep wall, to prevent damage to corals and avoid stirring up sediment. Always dive with a reputable operator, follow your guide's instructions, and stay within your certification limits. Be mindful of marine park regulations, as it is a protected area, and practice responsible diving to preserve the delicate ecosystem.
