Tres Reyes Islands & the Best Beaches Near Gasan, Marinduque: Your Complete Island-Hopping Guide
If you’ve ever stood on the beach in Gasan at sunset, you’ve seen them — three small dark shapes rising out of the water about 30 minutes by boat from shore. Those are the Tres Reyes Islands, named after the Three Kings of the nativity story: Gaspar, Melchor, and Baltazar. Today the islands are protected as a marine sanctuary, and they are the headline island-hopping experience anywhere in Marinduque.
This is your complete guide to the Tres Reyes — what to expect on each island, how to plan a trip, what to bring, when to go, and where the other great beaches in the area are. If you only do one boat trip during your visit to Marinduque, do this one.
The Three Kings: Gaspar, Melchor, and Baltazar
The Tres Reyes Islands sit roughly five kilometers off the coast of Barangay Pinggan in Gasan. Tradition holds that they were named in the Spanish colonial era after the three biblical Magi. They have been a designated marine sanctuary since 1999, which means a small number of fishing boats are still permitted but commercial fishing is banned — and the reefs have rebounded accordingly.
From the beach in Gasan, you’ll see them most clearly in the late afternoon. From the air on the way into Marinduque Airport, they look like green commas in a turquoise sea. Up close, each island has a distinct character.
Gaspar Island
Gaspar is the largest of the three and the only one with a small permanent population. It has a short stretch of crushed-coral beach, clear blue-green water shallow enough to wade in, and gentle reefs that begin within a few meters of shore. Most island-hopping itineraries spend the longest stop here — typically two to three hours for swimming, snorkeling, and lunch. There is a single small store and basic toilet facilities, but bring everything else you need.
Melchor Island
Melchor is smaller and steeper, with precipitous coral cliffs that drop straight into the water. It is the favorite of divers because of its underwater caves and bigger pelagic fish. There is no proper landing beach, so most trips circle Melchor for photos rather than stopping to swim — though you can absolutely snorkel directly off the boat in calm weather.
Baltazar Island
Baltazar is the smallest and most rugged. Like Melchor, its coastline is largely cliff, with a few hidden underwater caverns and very dramatic rock formations. The Baltazar Island Lighthouse is a notable historic landmark visible from passing boats. Together with Melchor, it provides the deeper-water dive sites for the area. Strong swimmers and certified divers will get the most out of these two.
Why Gasan is the Perfect Base
Most visitors organize their Tres Reyes trip from Gasan for a simple reason: it’s the closest jumping-off point. The boats leave directly from the Gasan shoreline, the trip out is the shortest of any port in Marinduque, and the same coast offers the best sunset views in the province for when you return.
Gasan is also a 10-minute tricycle ride from Marinduque Airport (MRQ) and a comfortable hour and a half from Boac, making it an easy base for the whole island. The town itself is quiet — a fish market, a few sari-sari stores, a couple of resorts — but the beachfront stretch along the national highway has a few standout properties, including Luxor Resort and Restaurant, whose private shoreline looks straight out at the Tres Reyes.
How to Plan Your Tres Reyes Trip
Booking the boat is straightforward. There are two main ways:
- Direct from the beach: Walk down to the Gasan shoreline in the morning and ask any of the registered banca operators. Rates are fixed by the local tourism office and posted on a board: roughly ₱600–₱800 for Gaspar Island only, or ₱1,500–₱2,000 for the full circuit of all three. The boat fits 6–8 people, so per-person costs drop quickly with a group.
- Through your resort: Most resorts in Gasan, including Luxor, can arrange the boat for you the night before, including the snorkel gear, a guide, and packed lunches. This is the easier option if you’d rather skip the negotiation.
Plan for a full half-day at minimum. A standard itinerary leaves Gasan around 8 AM, reaches Gaspar by 8:30, spends the morning swimming, circles Melchor and Baltazar around midday, and returns to Gasan in the early afternoon. Marinduque Guide’s island-loop itinerary maps out a full-day version with pacing notes.
What to Bring
- Reef-safe sunscreen (chemical sunscreens are discouraged in marine sanctuaries).
- Snorkel mask, fins, and a snorkel — most resorts can lend these, but bringing your own is more comfortable.
- A dry bag for your phone, wallet, and any electronics.
- Drinking water — at least 1 liter per person, more on hot days.
- Packed lunch or trail snacks — Gaspar has only one small store.
- A rash guard or light long sleeves; the equatorial sun reflects fiercely off the water.
- Pesos in small denominations for tips and any optional fees.
Other Beaches Worth a Day Trip from Gasan
The Tres Reyes are the headline experience, but they are far from the only good beach day available from Gasan. A few favorites within an hour or two by tricycle or hired van:
Poctoy White Beach (Torrijos)
On the eastern coast about 90 minutes from Gasan by van, Poctoy is the longest stretch of public white-sand beach in Marinduque — almost a kilometer of powdery sand with Mt. Malindig framing the horizon. It’s a popular weekend picnic spot for local families.
Maniwaya Island (Santa Cruz)
In the north of the province, Maniwaya is the white-sand island most often compared to Boracay and Palawan. The water is glassy turquoise, the sand is exceptionally fine, and at low tide a long sandbar called Palad emerges from the sea. Plan for a full day — Maniwaya is a 90-minute drive plus a 30-minute boat ride from Gasan.
Gasan’s own beachfront
If a half-day Tres Reyes trip is enough adventure for one day, the Gasan shoreline itself is a perfectly good place to spend the afternoon. The water is calm, swimmable, and uncrowded. Several resorts including Luxor offer day-use access to lounge chairs and showers if you’re not staying overnight.
The Best Time to Go
March through May are the prime months. Visibility around the reefs is excellent, the water is calm, and the weather is reliably sunny. June through October brings the southwest monsoon and unpredictable swells — boats often won’t run on rough days. November and December are typically calm again with cooler air, though the water gets a little murkier from runoff.
If you’re combining your Tres Reyes trip with the Moriones Festival in Holy Week (late March or early April most years), the timing is ideal: the festival runs in the daytime, and the boats run in the morning, so a half-day on the islands before joining the afternoon procession is a perfect Marinduque day.
Where to Stay: Beachfront in Gasan
There is no better location to base a Tres Reyes trip than Luxor Resort and Restaurant. The resort sits directly on the Gasan beachfront — the same shoreline the bancas leave from — meaning you can wake up, walk twenty meters, and step onto the boat. The chalets are air-conditioned, with hot and cold showers, cable TV, and Wi-Fi. The on-site restaurant serves authentic Italian pizza and pasta as well as Filipino classics, and the lush garden grounds make the whole place feel like a private retreat.
It’s family-run, well reviewed, and just three kilometers from the airport. Booking ahead during peak season (March–May and Holy Week) is essential.

Final Thoughts
The Tres Reyes Islands are the kind of destination that quietly out-performs places ten times more famous. They are protected, uncrowded, and easy to reach. The water is clear, the reefs are alive, and the boat ride is short enough that even reluctant snorkelers come back asking when the next trip is. Pair a morning on the islands with a sunset on the Gasan beachfront, a wood-fired pizza for dinner at Luxor, and you have one of the most rewarding 24 hours anywhere in the central Philippines.
Just go. And bring a friend who you know will fall in love with the place — that way you’ll have someone to come back with.
