Gato Island is a 1-hectare rocky islet rising from the Visayan Sea between Malapascua and Carnaza Island. Its name comes from the Spanish for “cat” — the island’s profile from a distance resembles a curled sleeping cat. Administratively it falls under Daanbantayan, Cebu, and has been a protected marine sanctuary since 1997, when the local government formally declared it a sea snake and fish sanctuary following the discovery of a sea krait breeding ground in the early 1930s.
In 2001, the protected zone expanded to a 2-nautical-mile radius. Then in 2015, Executive Order 16-2015 designated Monad Shoal and Gato Island as the Philippines’ first shark and ray sanctuary, prohibiting the catching and trading of all shark and ray species within these waters.
The island itself is uninhabited and has no facilities. Divers access it exclusively as a day trip from Malapascua, roughly an hour by banka boat. Most Malapascua dive centers offer combined Monad Shoal + Gato Island day packages, letting you tick off thresher sharks at dawn and cave sharks by midmorning.
The signature dive. A 30-meter tunnel passes completely through the island from one side to the other, with the interior lined in daisy soft corals and sponges. Lobsters, crabs, cleaner shrimp, and puffer fish inhabit the passage. Whitetip reef sharks rest in side alcoves and circle near the exits — patience and slow movement frequently result in face-to-face encounters at arm’s length. Torch required. Advanced Open Water certification required due to the overhead environment and depth of 18–22 m. Current can accelerate at the exit.
An extensive rock formation site where limestone pinnacles rise toward the surface and light penetrates at sharp angles. The topography creates natural corridors where schools of big-mouthed mackerel sweep through, and whitetip reef sharks have been observed in groups of up to 15 circling the upper formations. Depth: 10–20 m. Suitable for Advanced Open Water divers.
The most accessible site on the island, sloping from 8 to 24 m. Pink and yellow pygmy seahorses are found on the sea fans at depth. Spanish dancers, lionfish, painted frogfish, and multiple nudibranch species populate the wall on the ascent. This is the only Gato site regularly offered to Open Water divers.
A dedicated macro site where nudibranch density is concentrated in a compact area. Hermit crabs, scorpionfish, and assorted reef critters accompany the nudibranchs. Depth: 8–15 m. Advanced Open Water recommended due to site layout.
A channel site specifically productive for shark encounters. Whitetip reef sharks rest under ledges and move through the alley in small groups. Divers are 95% likely to find whitetips sleeping under rocks here, making it a reliable backup if the Tunnel is too congested. Depth: 10–18 m.
Gato Island’s resident species include banded sea snakes, cuttlefish, seahorses, nudibranchs, frogfish, scorpionfish, porcupine fish, and schools of squid. Whitetip reef sharks, bamboo sharks, and cat sharks maintain permanent residence, while schools of big-mouthed mackerel patrol the open water around the reef.
At the Guardhouse, pygmy seahorses in pink and yellow colorations are found at 24 m. Spanish dancers at Gato reach up to 30 cm. Juvenile pinnate batfish, harlequin shrimp, sea moths, and peacock mantis shrimp have all been documented on recent liveaboard dives. Whitetip shark sightings are most consistent from November to May, though sharks are in residence year-round.
Banded sea kraits are endemic to the sanctuary status and appear throughout the year. The breeding sea snake season lasts from March to September, when concentrations are highest in and around the tunnel entrance.
November–May is the recommended window. Visibility peaks at 20–25 m, seas are calmer, and whitetip shark activity is most predictable. Water temperature ranges from 24–30°C, with cooler temperatures corresponding to the northern hemisphere winter months.
June–October diving remains viable. Sea snakes are more active (breeding season), visibility dips to 10–15 m during wetter months, and boat crossings from Malapascua can be choppy. The Tunnel dive is still operational but check with your operator on sea conditions before committing to the crossing.
There is no single off-season — Gato runs year-round because the marine life has no seasonal dependency on external factors like currents or thermoclines. Most Malapascua operators include Gato trips on a rotating basis regardless of month.
Depth range: 5–24 m across all sites
Visibility: 10–25 m (season-dependent)
Current: Mild to moderate at most sites; the Tunnel exit can produce stronger flow
Water temperature: 24–30°C
Overhead environment: The Tunnel requires a torch and Advanced Open Water certification minimum
A 3 mm wetsuit suffices for most divers November–May; 5 mm during cooler months (January–February). Torch is mandatory for the Tunnel — your operator will typically provide one. Bring a surface marker buoy for open-water ascents around Cathedral and Whitetip Alley where current can push divers off the reef. Macro photographers should pack a diopter; the Guardhouse and Nudibranch City reward +5 or +10 wet lens use.
Complete your PADI Advanced Open Water before the trip if you want access to all five sites, including the Tunnel.
Gato Island has no medical facilities, diver rescue equipment, or emergency oxygen on-site. All first aid resources travel with your dive operator’s boat. The nearest hyperbaric chamber is in Cebu City (approximately 6–7 hours from Malapascua by road and sea). Confirm that your operator carries emergency oxygen before booking — reputable Malapascua centers like Thresher Shark Divers and Evolution Diving do. Do not attempt the Tunnel dive without an experienced guide familiar with the site’s current patterns.
Gato Island is uninhabited with no accommodation. All divers base themselves on Malapascua Island and make the 45–60 minute banka crossing each day. Browse dive resorts and accommodations in the Malapascua directory or compare rates through Agoda. Most Malapascua resorts offer dive packages that bundle accommodation with Gato Island day trips.
Gato Island has no resident dive operation. All diving is organized through scuba diving schools and centers based on Malapascua Island, approximately 1 hour by banka boat.
Leading operators running regular Gato Island day trips include Thresher Shark Divers (PADI Five Star IDC center; small-group format with experienced divemasters), Evolution Diving (PADI Five Star center and founding member of the Malapascua Marine Protection Fund), and Kokay’s Maldito Dive Resort (resort-based operation for guests and walk-ins).
Gato Island appears on Visayas liveaboard itineraries departing from Cebu City and Malapascua. The S/Y Philippines Siren includes Gato on its 10-night Visayas trips, and M/V Seadoors visits on 6-night itineraries, with occasional 12-night journeys. Liveaboards typically allocate 2–3 dives at Gato as part of a broader Visayas circuit that also includes Malapascua, Bohol, and Negros dive sites.
Compare schedules on Liveaboard.com and Divebooker. Browse liveaboard operators in the directory for Philippines Visayas itineraries.
Gato Island has no gear shops, and Malapascua’s retail options are limited to basic rental equipment at dive centers. Bring spare O-rings, batteries for your torch, and any specialized macro gear from Cebu City before traveling north. Browse dive gear shops in the directory for Cebu City options before your trip.
Gato Island carries dual protection status. In 1997, it was designated a sea snake and fish sanctuary by Daanbantayan resolution. In 2001, the protected zone was expanded to a 2-nautical-mile radius managed by the municipal government. The 2015 Executive Order extended shark and ray sanctuary status jointly with Monad Shoal — the first such designation in the Philippines.
The Malapascua Marine Preservation Fund — established in 2010 — funds Bantay Dagat (sea watch) patrols around Gato and Monad Shoal. Many Malapascua dive operators collect a small conservation levy from divers that goes directly to patrol boat operating costs and patrol staff salaries. Ask your operator whether their dive fee includes a contribution to the MMPF.
The sea krait populations at Gato are a direct result of the 1997 sanctuary designation halting fishing pressure. Disturbing sea snakes in their nesting areas is prohibited under sanctuary rules. Marine sanctuary fees collected at Gato are administered by the municipal government of Daanbantayan with a portion allocated to site monitoring.

Gato Island is an uninhabited marine sanctuary with no above-water activities. Day-trippers spend surface intervals on the boat or in the shallows before returning to Malapascua. All non-diving activities are based on Malapascua Island, which offers beach walks, snorkeling, and island-hopping tours to Kalanggaman Island. Book activities through Klook for Cebu-area experiences to pair with your Malapascua stay.
Community Vibe: Gato Island itself has no community — it is uninhabited. All diver interaction with locals occurs on Malapascua Island, which has a tight-knit dive tourism economy. The island is small, walkable, and relaxed. Solo travelers integrate easily through dive center social settings. Malapascua’s tourism is almost entirely dive-driven, so the local community is highly diver-oriented and English communication is standard at all dive facilities.
Tipping Culture: Tipping dive guides and boat crews is appreciated but not required or expected. PHP 100–300 (~USD $2–5) per dive for a guide who delivered genuine value is a reasonable gesture. Never feel obligated.
Safety & Scam Awareness: Gato Island itself poses no scam risk. At Maya Port, confirm your boat fare before boarding and keep luggage visible. On Malapascua, touts may approach at the pier — walk directly to your pre-booked accommodation. Confirm all dive fees and sanctuary charges in writing before departure to avoid unexpected additions on return.
Fly into Mactan-Cebu International Airport (CEB). From the airport, take a taxi or Grab to Cebu North Bus Terminal (approximately 45 minutes, PHP 300–500 / ~USD $5–8 by Grab). From the bus terminal, catch a bus or van to Maya Port (also called New Maya or Maya New Roro Port). Bus fare runs PHP 150–200 (~USD $2.50–3.30); the journey takes 3.5–5 hours depending on traffic. Minivans are faster but may wait to fill seats before departing.
At Maya Port, pay the environmental fee (PHP 30–50 / ~USD $0.50–0.80), then board a pump boat to Malapascua (PHP 100–150 / ~USD $1.70–2.50 per person, 30 minutes). Last boats typically leave Maya by late afternoon — confirm current schedules with your resort.
Book transport in advance via Bookaway or 12Go to lock in bus or van seats.
All dive operators on Malapascua arrange banka boat transport to Gato as part of their trip pricing. The crossing takes approximately 45–60 minutes and is included in day-trip packages. Privately arranging a banka is possible but unnecessary and more expensive than booking through a dive center.
Duration: Gato Island works as a half-day or full-day excursion from Malapascua. Most 2-tank Gato packages depart around 7–8 AM and return by 1–2 PM, leaving afternoons for Malapascua local dives such as the Lighthouse mandarin fish dive or the Dona Marilyn wreck.
Certification: Advanced Open Water is effectively required to dive the best sites. Open Water divers are limited to the Guardhouse and must be accompanied by an instructor.
Dive Insurance: Purchase before you travel. The nearest recompression chamber is in Cebu City, and an emergency evacuation from Malapascua involves boat transfer, road transit, and potential airlift costs. Cover yourself through DAN, Diveassure, or SafetyWing.
Accommodation: Browse dive resorts and accommodations on Malapascua or compare rates through Agoda. Most Malapascua resorts offer dive packages that bundle accommodation with Gato trips.
Liveaboards: For divers combining Gato with broader Visayas coverage, compare multi-day itineraries through liveaboard operators in our directory.
Yes, for the Tunnel, Cave, Cathedral, Nudibranch City, and Whitetip Alley sites. The Guardhouse site is accessible to Open Water divers with an instructor. Most Gato packages are marketed toward Advanced divers — confirm your certification level when booking.
Yes. The island is uninhabited with no facilities. All divers base themselves on Malapascua Island and make the 45–60 minute crossing each way.
Banded sea kraits (Laticauda colubrina) are venomous but are not considered aggressive toward divers. They are hunting reptiles that surface to breathe — do not block their path to the surface or attempt to handle them. Incidents involving sea kraits are extremely rare.
No. Thresher sharks are encountered at Monad Shoal and Kimud Shoal, not at Gato. Gato’s shark species are whitetip reef sharks, bamboo sharks, and cat sharks. Many Malapascua operators offer combined packages (threshers at Monad/Kimud + sharks at Gato) on the same day.
Early morning light penetrates the tunnel more dramatically, but the dive itself is not light-dependent given torch use. Go early to avoid boat congestion at the tunnel entrance — it is a popular site and multiple operator boats arriving simultaneously creates crowding in a confined overhead environment.
Basic rental gear is available at all major Malapascua dive centers. Dedicated dive gear shops for purchases or specialist equipment are limited — bring spare O-rings, torch batteries, and any specialized macro gear from Cebu City before traveling north.
