Dive Site: Monad Shoal

About Monad Shoal

Monad Shoal is a submerged island positioned at the edge of a deep drop-off, approximately 200 meters, near Malapascua Island in the Philippines. It gained global recognition as a consistent location for encounters with pelagic thresher sharks. This underwater plateau is attractive to pelagic species that ascend from the surrounding deep waters, serving as a cleaning station for these creatures, including giant manta rays, devil rays, and eagle rays. The shoal's topography includes reef sections, rocky areas, slopes, and cleaning station habitats. The shallowest parts of the plateau begin at depths between 12 and 14 meters, but its slopes and walls extend well beyond typical recreational diving limits. Divers usually descend to around 30 meters to reach the top of the shoal where the thresher sharks are often seen. Thresher sharks are present year-round, though sightings are never guaranteed as their movements are influenced by currents, food availability, and other environmental factors. While historically the primary site for thresher shark encounters, recent observations also highlight Kimud Shoal for similar sightings. Giant manta rays are also a common presence throughout the year. Occasionally, whale sharks, tiger sharks, and hammerheads may also be spotted. Due to the significant depths and potential for strong currents, Monad Shoal is recommended for advanced divers with deep diving experience and good buoyancy control. Nitrox is beneficial to maximize bottom time while waiting for shark appearances. Entry is always by boat, and while currents can be present, dive schedules are often adjusted based on current sightings and sea conditions.

Conditions & Currents

Monad Shoal can experience strong currents, particularly at certain times. Divers should be prepared for these conditions, listen to their dive guides, and maintain close proximity to their buddies. These currents are an important factor in the pelagic activity at the site.

Dive profile & how the dive runs

Dives to Monad Shoal are typically scheduled early in the morning, around 4:30–6:00 AM, to coincide with the thresher sharks' visits to cleaning stations. After a 30-40 minute boat ride from Malapascua Island, divers receive a briefing covering conditions and the planned route. The dive usually begins with a negative entry and a rapid descent to a sandy plateau at approximately 20-25 meters, often extending to 30 meters. Divers position themselves along a designated viewing line or area, remaining still and quiet to observe the shy thresher sharks. The dive progresses along the edges of the shoal, which rises from deep surrounding water and features reef, rocky areas, and slopes. Beyond the main thresher shark viewing, divers can look for manta rays and macro life on the reef. Maximum depth can reach 40 meters on the outer edges. The safety stop is conducted as the dive concludes, often drifting in medium to strong currents.

Underwater photography

Monad Shoal offers unique photography opportunities, particularly for wide-angle shots of thresher sharks. Given the early morning dives and minimal ambient light before sunrise, photographers should prepare with fast ISO settings and be proficient in low-light techniques. Using strobes is often restricted or advised against for thresher sharks, as they are light-sensitive. Focus on capturing the natural behavior of these pelagic creatures without disturbing them. For macro enthusiasts, Monad Shoal also hosts diverse critter life, including pygmy seahorses, nudibranchs, and mantis shrimp. A 60mm or 105mm macro lens is ideal for these smaller subjects, especially when visibility allows or during later dives on the shoal. Strong buoyancy control is crucial to avoid disturbing the sandy bottom or coral formations.

Getting there & logistics

To reach Monad Shoal, you first travel to Malapascua Island, located off the northern tip of Cebu. The nearest international airport is Mactan-Cebu International Airport (CEB). From Cebu City, the journey to Malapascua involves a bus or private transfer to Maya Port, followed by a local boat transfer to the island. Dive trips to Monad Shoal depart daily from Malapascua resorts, typically very early in the morning (around 4:30-6:00 AM) due to the thresher sharks' habits. The boat ride to the shoal takes approximately 30-40 minutes. Trips are usually resort-based, as liveaboards rarely visit Malapascua's shallow reefs. A marine park fee for Monad Shoal is generally included in dive packages. Malapascua itineraries often combine thresher shark dives with trips to Gato Island, Kimud Shoal, and local macro sites.

Safety & environment

Diving at Monad Shoal requires careful adherence to safety protocols due to its depth and potential currents. The site's pelagic nature means divers must be proficient in buoyancy control and comfortable with deeper dives and potential drift. The nearest recompression chamber is typically in Cebu City, which entails a multi-stage evacuation process involving boat and land transport, potentially taking several hours. Dive insurance covering medical emergencies and evacuation is strongly recommended. Divers are briefed on descent procedures, maximum depth limits (often 25-30 meters for thresher shark encounters), and ascent protocols. Remaining quiet and still at the cleaning stations is crucial to avoid scaring the shy thresher sharks. Always dive with experienced local guides who understand the specific conditions and behavior patterns of marine life at Monad Shoal.
