Seafan Alley

Gorgonian fan corals beautifully adorn the northernmost area of Tubbataha Atoll, making it a must-visit spot for divers. This dive site is perfect for advanced divers who are looking for an exhilarating wall drift diving experience.

When exploring the depths, you may come across nurse sharks and marble rays, often found lazily resting on the white sandy ledges inside caverns. The area is also frequented by whitetip sharks and grey reef sharks, gracefully patrolling their territory.

As you venture deeper, you'll be mesmerized by the poetry of the wall itself. Caverns, cracks, and crevices interspersed with stunning gorgonian fan corals create a scene of unparalleled beauty and grace. Along the sandy embankment where the reef meets, eagle rays have made their home, while the elusive silvertip tip sharks occasionally make an appearance. Devil rays and manta rays can also be spotted gliding through the blue ocean depths.

Amongst the vibrant array of fan corals, the pygmy seahorse reigns over its territory, adding a touch of enchantment to the dive. As you make your way towards your safety stop at the end of the dive, you'll have the opportunity to marvel at the reef top, with depths as shallow as 3 meters. Crisscrossing channels define the incoming and outgoing water currents, originating from the lagoon that dominates the inner part of the atoll. Schooling big eye trevally and giant trevallies bid farewell, creating a memorable end to your dive.

With a visibility of 20 meters and a maximum depth of 25 meters, this dive site offers an immersive experience for advanced divers seeking to explore the wonders of Tubbataha Atoll. Don't miss out on the chance to dive into this underwater paradise that promises to leave you in awe.
