Manta Bowl is a small seamount in the Ticao Pass, a deep, nutrient-rich channel between Ticao Island and the Bicol mainland that draws reef mantas to its cleaning stations year-round. The site sits about 7 km off Ticao’s western coast, which serves as the main dive base — a single beachfront resort, short boat runs to the pass, and little other traffic. Beyond the bowl, the area runs to wall and tuna sites in the channel and macro-rich reefs around the San Miguel islets to the north.
The Ticao Pass is one of the few major Pacific inlets feeding this part of the Visayas, and the constant current carries plankton that supports filter-feeding megafauna. That dynamic is what made Manta Bowl significant enough for researchers to set up shop here; it also keeps the destination raw, with limited infrastructure, intermittent power and signal, and weather windows that genuinely affect access.
The dive base is Ticao Island — four municipalities (Batuan, San Fernando, San Jacinto, Monreal), with San Jacinto as the commercial center. There’s no airport, no resort strip. One main property on the western coast operates the on-site dive center and most of the boats; the sites are scattered across the pass and the San Miguel islets to the north.
This is an emerging destination, not a polished one. International tourism has barely touched the area, and the diving has the feel of a frontier site that researchers reached before the crowds did. Divers come knowing the trade-off for uncrowded mantas is rougher logistics.
The diving splits into two zones: the Manta Bowl shoal in the pass (big-animal drift, advanced) and the San Miguel and northern reefs (macro and coral, all levels).
| Dive Site | Depth | Level | Highlight |
|---|---|---|---|
| Manta Bowl | 14–25m | Advanced | Reef manta cleaning stations |
| Tuna Alley | 18–25m | Intermediate | Skipjack schools |
| Great Wall of Ticao | 5–40m+ | Advanced | Vertical wall, soft coral, tuna |
| Bobby’s Wall | 5–25m | All levels | Macro on coral and sand |
| San Miguel reefs | 5–20m | All levels | Soft-coral gardens, critters |
A small seamount roughly 7 km offshore, rising from around 200 meters to a reef flat of about 6 hectares between 14 and 25 meters, then tapering past 50 meters. Several cleaning stations host reef mantas hovering while wrasse remove parasites. Currents commonly run 2–3 knots — strong enough that this is a drift dive, and divers use reef hooks at the stations to hold position without contacting the reef. The bowl is small relative to visibility, so encounters aren’t guaranteed on any single dive; multiple dives over several days improve the odds significantly.
A reef and slope formation in the pass where skipjack tuna come through on the current. Intermediate level, depths usually 18–25 meters; conditions track the same lunar pattern as Manta Bowl.
A vertical wall off an islet north of the main site that drops past recreational limits, with rock formations breaking the surface above. Soft corals, sea fans, and nudibranchs on the face, tuna patrolling the blue. Best in calm conditions given its exposure.
On the northern side of San Miguel Island. The site mixes sandy slope, ledges, reef wall, and overhangs, and despite the name divers often spend the whole dive on the coral and sand before reaching the wall — frogfish, nudibranchs, pipefish, stonefish, and Coleman shrimp on fire urchins.
A cluster of sites around the San Miguel islets at the northern end of Ticao, 45–60 minutes from the western-coast resort. Soft-coral gardens in the shallows, with a strong critter list — seahorses, orangutan crabs, nudibranchs, and mandarinfish among them. Good for check-out dives and night diving.
Mantas and rays. Reef mantas are the main draw, gathering at Manta Bowl’s cleaning stations across the year. Both reef and oceanic mantas have been documented across the wider Ticao-Burias Pass, which LAMAVE has confirmed as the country’s primary reef-manta aggregation.
Pelagic sharks. The pass attracts whale sharks roughly November–June and threshers roughly July–October, with occasional hammerheads and tigers. The deeper channel is also part of the documented range of the rare megamouth shark (Megachasma pelagios).
Reef and macro. The northern reefs around San Miguel and Bobby’s Wall shelter frogfish, robust ghost pipefish, seahorses, mandarinfish, stonefish, nudibranchs, orangutan crabs, and Coleman shrimp. Soft corals, barrel sponges, and sea fans dominate the coral cover.
Other megafauna. Dolphins, sea turtles, and schooling tuna show up regularly in the pass, reflecting the plankton-driven food web that defines the area.
Peak season (November–May). Dry months bring the calmest seas, best access, and overlapping windows for whale sharks and year-round mantas — the most reliable period for pelagic encounters. Exposed sites like Great Wall are most consistently accessible in this window.
Wet season (June–October). The habagat brings rougher water and reduced visibility, though threshers are most likely then. Trips remain possible but more weather-dependent, and crossings to the island can be disrupted.
Visibility in the pass runs green and variable year-round given the plankton load — divers come for the animals, not for clear blue water.
Manta Bowl is an advanced-leaning site. The seamount and the wall sites involve strong, sometimes 2–3 knot currents that demand solid buoyancy, drift-diving skill, and comfort with reef hooks. The northern San Miguel reefs are gentler and suit newer divers and training.
Water temperature sits in the high 20s Celsius (roughly 27–29°C / 80–84°F) most of the year. Visibility is variable — the same nutrient load that draws the megafauna keeps the water green, often 10–15 meters and sometimes less after rain or wind.
The PADI Drift Diver specialty or an Advanced Open Water cert is worth completing before arrival.
Recommended gear: A reef hook is essential for the cleaning stations. A 3mm wetsuit is enough; an SMB and an audible signaling device are sensible given the current and the open-water nature of the seamount dives.
Ticao is remote. The nearest recompression chambers are in Cebu City (TIEZA Mandaue, and the multi-place chamber at Cebu Doctors University Hospital), and evacuation times from the island are long. Dive conservatively, build in surface intervals, and carry dive insurance with evacuation cover. Nitrox availability is limited — confirm with the operator in advance.
Accommodation centers on a single beachfront dive resort on the western coast, which operates the on-site PADI dive center and runs boats to Manta Bowl and the northern reefs. Rooms are rustic — fan or AC bungalows, full-board meals, intermittent power and signal rather than luxury finishes. Outside the resort, basic guesthouses exist in the towns, and some divers base in Donsol on the mainland and run longer trips out.

Diving runs almost entirely through the island’s resort-based PADI dive center, which handles fun dives, courses from Discover Scuba through Divemaster, and boat logistics. A second small operation works with a separate resort. Advance booking is essential — there’s no walk-up dive scene here. Online theory is usually available so the classroom portion can be done before arrival.

There’s no resident liveaboard fleet on Ticao, but Manta Bowl and the wider Ticao Pass appear on itineraries run by Philippine liveaboards that combine the area with Donsol’s whale sharks and other Bicol and Visayas sites. Compare routes on Liveaboard.com and Divebooker, or browse the liveaboard listings.
Ticao has no dive-retail shops. The dive center carries rental kit and basic consumables, but there’s no walk-in store for purchases or specialty items. Bring everything you need — reef hook, spare mask strap, save-a-dive essentials — and buy or service major gear in Manila, Cebu, or Legazpi before traveling. For retail elsewhere in the country, the dive gear shops listings cover what’s around.
Manta Bowl sits within the Ticao-Burias Pass Protected Seascape, established in June 2018 and covering 414,244 hectares across Albay, Masbate, and Sorsogon — the second-largest seascape in the Philippines after Tañon Strait. A Protected Area Management Board oversees enforcement, with seaborne patrols and mangrove monitoring under the DENR’s coastal management program.
The site has been a LAMAVE manta-research project since 2017, using photo-ID, acoustic telemetry, and remote underwater video to study the reef-manta population. The pass is also recognized as an Important Shark and Ray Area (ISRA).

Ticao Island is quiet, and the appeal off the water is its rawness rather than a packed activity list.
Island hopping. Boats from Monreal reach the San Miguel islets, hidden coves, and Catandayagan Falls, which spills directly into the sea. Charter a bangka for a half day.
Catandayagan Falls. A waterfall dropping over a cliff face onto the shoreline, reached by boat.
Beaches and lagoons. White-sand stretches and natural pools dot the coast, almost always empty.
Horseback riding. The main resort keeps free-roaming horses on its grounds.
Book transfers and activities across the wider Bicol region through Klook.
Ticao is a working fishing-and-farming island, not a tourist town. The dive community is tiny and centered on the resort, where the atmosphere is relaxed and family-run. Solo travelers are safe and well looked after, though the isolation is real — limited signal, occasional blackouts, and few other foreigners.
Customs. A few words of Filipino or the local Bikol or Masbateño dialect go a long way. Dress modestly away from the beach, and ask before photographing people.
Tipping. Appreciated but not required or expected. A modest tip for dive guides and resort crew is generous when warranted.
Ticao is low-crime and low-hassle — the main risks are logistical, not criminal. Confirm boat and ferry schedules directly, since published times shift and trips are weather-dependent. When chartering a bangka, agree the price before departing. Carry enough cash; ATMs are scarce and unreliable, and the resort and operators largely run on cash.
There’s no airport on Ticao Island — reaching the dive base takes a flight plus a boat.
Fly Manila or Cebu into Bicol International Airport (DRP) in Daraga, next to Legazpi — the airport replaced the old Legazpi Airport (LGP) in October 2021. From the terminal, take a tricycle to the city, then a bus or van to Pilar Port in Sorsogon (around PHP 120 / ~USD $2, 1–2 hours). From Pilar, the ferry to Monreal Port on Ticao runs around PHP 120 (~USD $2) plus a small terminal fee, takes roughly 1.5 hours, and operates on a limited daily schedule — commonly a single midday departure out and an early-morning return. Most divers pre-arrange a resort transfer to coordinate the connections. Compare ground transport on Bookaway or 12Go; compare flights on Trip.com.
Some divers base in Donsol on the Sorsogon mainland — about 45 minutes from Bicol International Airport — and pair Manta Bowl diving with Donsol’s whale-shark snorkeling. The boat run to Manta Bowl from Donsol is longer (up to two hours) than from the Ticao base.
Fly Manila to Masbate (MBT), then take a public boat to Ticao and overland transport across the island. The sea crossing is shorter, but flights are less frequent.
On the island, tricycles and habal-habal (motorbike taxis) link the towns, and bangka charters cover island hopping and dive transfers. Most diving logistics are handled by the resort.
Booking. Book accommodation and diving well in advance — the island’s capacity is small and the main resort fills around peak windows. Confirm transfers when you book; coordinating flights with limited ferry departures is the trickiest part. Allow buffer days for weather.
Dive insurance. Given the remoteness and long evacuation times, dive-specific cover is non-negotiable. Get covered before you dive: DAN or DiveAssure for dive-specific cover, or SafetyWing for broader travel and evacuation.
What to pack. A reef hook is essential for Manta Bowl. Bring a 3mm wetsuit, SMB, save-a-dive kit, and any specialty gear, since there’s no retail on the island. Pack enough cash for the whole stay, a power bank for the blackouts, and patience for the signal.
For the wider region, the Donsol dive guide covers the whale-shark base on the mainland.
No. Reef mantas are present year-round at the cleaning stations, but the reef flat is small relative to visibility, so encounters aren’t guaranteed on any single dive. Divers who do multiple dives over several days have far better odds than those passing through for one.
The dry season from November to May offers the calmest seas, best access, and overlapping whale-shark and manta windows. June to October is rougher but brings threshers. Mantas themselves are present all year.
For Manta Bowl and the wall sites, yes — strong currents and depth make Advanced Open Water and drift experience strongly advisable. The northern San Miguel reefs are gentle and suit Open Water divers and training.
Fly into Bicol International Airport in Daraga (next to Legazpi), then take a bus or van to Pilar Port and the ferry to Monreal on Ticao. Alternatively, fly to Masbate City and boat across. A resort-arranged transfer is the simplest option.
Not as a stated encounter. Whale sharks pass through the pass and may be seen on dives seasonally, but the famous interaction in Donsol is strictly snorkel-only and regulated.
Yes, though it’s low-key — island hopping to Catandayagan Falls and the San Miguel islets, empty beaches and lagoons, and horseback riding at the resort.
