Diving Ticao Island: manta rays in the Ticao Pass

The Manta Bowl puts Ticao Island’s diving on a current-swept shoal in the Ticao Pass, where reef manta rays use cleaning stations. This is a rural island base for boat diving, not a shore-diving holiday: each outing depends on tide, sea state and a workable crossing. The reward is the chance to watch mantas in open water, with occasional larger pelagic visitors, while San Jacinto and Talisay Beach provide a quiet place to sit out a weather-bound day.

The Manta Bowl is a shoal in the deep, nutrient-rich channel between Ticao and the Bicol mainland. Tidal currents can be strong, so the dive is handled as a drift dive rather than a gentle circuit over sheltered reef. Expect a boat departure, a planned descent, time in the current around the cleaning stations, then a controlled ascent and safety stop. A downcurrent is a real possibility, and good buoyancy control matters more here than a desire to cover ground. Visibility is often around fifteen to thirty metres, although plankton, rain and swell can reduce it sharply. That lower visibility is not necessarily bad news: the same plankton can bring the reef manta rays in. This is boat diving in changing conditions, with no simple shore-diving alternative if the sea turns awkward.

Reef manta rays are Ticao’s main attraction, and they can be encountered throughout the year, with the most dependable period generally falling between December and May. At the Manta Bowl, the focus is on their visits to cleaning stations: hold position in the current, watch the open water and let the animals make the approach. Plankton may soften the view, but it is also part of the food supply that brings the mantas close. Whale sharks can appear between December and May, although they are occasional rather than a dependable feature of every trip. Thresher sharks are also occasional, with local diving accounts placing their better chance between June and October.

December to May is the practical window for Ticao, with a generally more manageable sea and more reliable access to the Manta Bowl. May and June can bring clearer water, but the plankton that attracts mantas may reduce visibility at any time. From June to October, the rainy season and south-west monsoon make crossings and boat dives more vulnerable to disturbed conditions. Mantas remain present outside the main season, but a flexible itinerary matters more then. The best balance is several days between December and May, rather than a short visit built around one weather-dependent outing.

The Manta Bowl suits experienced divers who are comfortable in strong current and changing conditions. Advanced Open Water, or a BSAC, PADI or SSI equivalent, is useful for the deeper, current-affected diving, while a Drift Diving speciality is genuinely relevant rather than decorative. You should already be able to descend, maintain position, respond to a changing flow and complete a controlled ascent without relying on the reef for support.

From London or Manchester, the journey needs both an internal flight or an overland connection and a sea crossing. One route uses a domestic flight to Masbate, followed by a boat from Masbate City to Ticao. The alternative is to travel overland to Bulan in Sorsogon, then take a ferry or fastcraft to San Jacinto. The Bulan crossing takes roughly one to one and a half hours, while boats from Masbate City take about an hour, depending on the vessel and port. Services run mainly in the morning and early afternoon, so allow room for missed connections and weather delays. On Ticao, stay near San Jacinto or Talisay Beach, with local transport arranged for the short land movements to the boat departure point.

Treat the Manta Bowl as a current dive, not as a guaranteed wildlife viewing platform. Bring the current-diving equipment you already trust, and make sure your buoyancy and drift-dive skills are current before travelling. Build in several attempts during the December to May window, because plankton can reduce visibility even when the mantas are present, and a rough sea can cancel the boat altogether. Keep a buffer day at both ends of the trip: boat departures are concentrated during daylight, and a delayed crossing can break the rest of the itinerary. Do not schedule a tight flight connection after the return crossing. Confirm the crossing on the intended day before committing to the dive plan. Finally, do not assume that the Ticao-Burias Protected Seascape automatically means a no-take area. Treat it as a conservation setting, while following the local rules in force.

Allow five to seven days on Ticao, with a land-based stay around San Jacinto or Talisay Beach and daily boat trips towards the Manta Bowl when the sea permits. Keep at least one day uncommitted for a cancelled crossing or missed weather window. Non-divers can use the beaches, go snorkelling, walk to waterfalls or take a local boat excursion, although the island remains rural and its land-based offer is modest. A quiet coastal day also works well before the journey home.
