Seafan Alley, Tubbataha: Wall Diving in Gorgonian Gardens

Seafan Alley begins on a shallow reef top at the North Atoll, gently sloping into a sandy area dotted with coral heads before dropping sharply. This transition from a flat, sunlit reef to a vertical face defines the initial profile of the dive, leading you towards the distinctive feature that gives the site its name. The upper section of the wall presents a complex topography of overhangs, small caves, and crevices, creating a varied environment from the outset.

As you descend, the wall becomes increasingly vertical, transforming into what's best described as a deep wall. This section is characterized by its dense coverage of large gorgonian sea fans, black corals, and soft corals, which extend along the reef for a considerable distance. These soft coral gardens create a vibrant, living tapestry against the wall, offering shelter and feeding grounds for a variety of reef inhabitants, including the often-sought pygmy seahorse and longnose hawkfish nestled within the fans.

The topography continues to evolve with ledges and barrel sponges punctuating the wall face, creating micro-habitats that support a rich diversity of life. While focusing on the intricate details of the wall, maintain awareness of the blue. Whitetip reef sharks and grey reef sharks are regular visitors patrolling the deeper sections, often joined by the more elusive silvertip shark. These encounters add a dynamic element to the dive, reminding you of the oceanic environment surrounding Tubbataha.

Beyond the resident reef species, Seafan Alley is also a convergence point for schooling fish. Large schools of bigeye jack and other jackfish, alongside giant trevally, are frequently observed moving along the current-swept wall. Tuna and barracuda also make appearances, often cruising just off the reef, presenting opportunities for encounters with larger pelagics in open water. This blend of resident reef life and transient hunters defines the site's rich biodiversity.

The diverse fish population includes numerous triggerfish, such as the red-toothed triggerfish, alongside sweetlips and midnight snapper. You will also see various snappers, wrasses, parrotfish, surgeonfish, and emperors actively feeding on the reef. Angelfish and pufferfish add to the vibrant tableau of reef fish, contributing to the visual richness as you move along the wall's contours. Hawksbill turtles and other sea turtles are also common, often seen resting on ledges or foraging among the corals.

What sets Seafan Alley apart from nearby North Atoll sites like Shark Airport or Washing Machine is this exceptional concentration of gorgonian sea fans and soft corals. While those sites might offer different attractions, here the emphasis is on the expansive, healthy growth that forms the 'alley' itself. This density of filter feeders indicates a consistent flow of nutrient-rich water, contributing to the overall health and productivity of the reef ecosystem.

Diving Seafan Alley often involves a boat entry directly along the wall section. Depending on the current, it can evolve into a gentle drift, allowing you to cover more ground along the extensive gorgonian gardens. While the focus is typically on the wall's intricate details and its inhabitants, keep an eye on the open water for larger pelagic sightings, as the site offers a blend of macro and wide-angle opportunities.
