Dive Site: Cathedral Rock

About Cathedral Rock

Cathedral Rock, a renowned dive site in Anilao, Batangas, Philippines, is easily accessible by a short boat ride from nearby resorts. This site features two prominent underwater rock formations, connected by a cross, which together create the impression of a grand cathedral, inspiring its name. The terrain ranges from shallow areas to deeper sections, accommodating various skill levels. What was once a barren rock formation was transformed into a vibrant ecosystem through coral transplantation efforts in the early days of scuba diving here, defying scientific expectations. Today, Cathedral Rock boasts healthy hard and soft coral reefs that teem with diverse marine life. Diving here reveals an abundance of colorful fish species, including large schools of snappers, jacks, surgeonfish, and fusiliers. Divers frequently encounter frogfish, moray eels, lionfish, and a variety of nudibranchs. Sea turtles are also a common sight, with occasional appearances by sharks and rays. The underwater cross serves as a unique landmark and a popular subject for underwater photography, having been blessed on land before its placement by General Fidel, who later became president. Cathedral Rock is celebrated for its rich biodiversity and is suitable for divers of all experience levels, from beginners to advanced. Visibility typically ranges from 10 to 30 meters, depending on conditions. Currents can vary from mild to moderate, making it generally accessible, though checking conditions before diving is always recommended. This marine hotspot also offers enchanting night diving for those seeking an adventurous experience.

Dive profile & how the dive runs

Dives at Cathedral Rock typically commence with a descent along the mooring line, leading directly into the amphitheatrical opening formed by the two prominent rock formations. The central focus is the concrete cross, situated at approximately 15 meters, where divers often begin their exploration. The dive path usually involves circling the cross and the 'main altar' area, observing schools of snapper, surgeonfish, and batfish. From there, divers can proceed to explore the outer faces of the rock formations, which slope down to around 20-25 meters. Shallower sections, ranging from 5 to 8 meters, are accessible on top of the formations. Overhangs and crevices provide shelter for smaller creatures, while sandy patches between the rocks are ideal for spotting gobies and macro subjects. The dive usually concludes with a safety stop conducted either near the mooring line or along the shallower reef top, allowing ample time to observe the abundant reef life.

Underwater photography

Cathedral Rock presents exceptional opportunities for both wide-angle and macro photography, thriving particularly during sunny days with mild currents when light shafts penetrate the water column. For wide-angle shots, a fisheye or wide-angle lens is ideal to capture the grandeur of the rock formations, the cross, and schools of fish swirling through the 'amphitheater'. Utilizing strobes is essential to bring out the vibrant colors of the corals and fish against the dramatic lighting. Macro photographers will find abundant subjects on the rock surfaces, which are carpeted with hard and soft corals, sponges, and hydroids, offering numerous nudibranchs, shrimps, and other small critters. Patient observation and excellent buoyancy control are crucial to avoid disturbing delicate marine life and to compose clear, focused shots. Subject etiquette is important here; avoid touching corals or marine animals, and maintain a respectful distance.

While currents are generally mild, they can occasionally strengthen, necessitating good buoyancy control and situational awareness, especially around the rock formations. The nearest recompression chamber is located in Batangas City, roughly an hour's drive from Anilao. In case of a dive emergency, evacuation to a medical facility would involve boat transfer to shore followed by land transport. Comprehensive dive insurance, covering medical emergencies and evacuation, is highly recommended for all divers. Site-specific rules include prohibitions against spearfishing and touching marine life, ensuring the preservation of this vibrant marine sanctuary. Divers should remain vigilant of boat traffic, particularly when surface swimming from shore, and follow dive guide instructions for entry and exit procedures.
