Dinagat Islands

Province Overview

The Newest Province in Caraga

The Dinagat Islands form Caraga's youngest and smallest province, officially established in 2013 after a prolonged effort to separate from Surigao del Norte. The province is composed of the main Dinagat Island and several surrounding smaller islands scattered across the Dinagat Sound — the channel separating Mindanao from the open Pacific.

Despite its modest size, the province harbours extraordinary natural attractions. The Sohoton Cove system at Bucas Grande features towering limestone cathedral arches, hidden lagoons, sea caves, and a stingless jellyfish sanctuary unlike almost anywhere else on earth. The island's coastline offers pristine beaches, dramatic rock formations, and bioluminescent plankton displays at night in certain bays.

San Jose serves as the provincial capital. The province is rich in nickel and chromite deposits, though natural attractions and sustainable eco-tourism are increasingly recognised as the islands' most enduring economic assets. The Dinagat Islands remain one of the least-visited island destinations in the Philippines — a frontier for travellers who prefer discovery over crowds.

Tourist Spots in the Dinagat Islands

Cathedral caves, bioluminescent lagoons, stingless jellyfish, and wild Pacific coastlines — Dinagat Islands is Caraga's hidden gem waiting to be discovered.

Cathedral Caves Map

Sohoton Cove — Cathedral Rock System

The Sohoton Cove system is the crown jewel of the Dinagat Islands — a series of towering limestone arches, sea caves, and hidden lagoons accessible only by navigating narrow tidal passages by boat. The Cathedral formation consists of vast cathedral-like chambers open to the sky, their walls draped in moss and stalactites, their floors filled with clear turquoise water. The passages through the rock can only be entered at low to mid tide, making every visit feel like a privileged secret. Ancient cave paintings found on the walls suggest the site has been sacred to human communities for thousands of years.

Jellyfish Sanctuary Map

Stingless Jellyfish Lagoon

Tucked within the Sohoton Cove limestone formation lies one of the Philippines' most extraordinary natural experiences — a sheltered lagoon filled with thousands of stingless jellyfish that can be touched and handled without harm. Isolated from the open sea by rock barriers over millennia, these jellyfish have evolved to lose their stinging cells entirely. Swimming or snorkelling among them — the golden globes drifting silently through clear water — is surreal and unforgettable. The lagoon is accessible only at specific tidal windows and requires a guided boat to navigate the cave passages that lead to it.

Bioluminescence Map

Basilisa Bioluminescent Bay

The bays around Basilisa municipality are among the few places in the Philippines where bioluminescent plankton can be reliably observed on calm, moonless nights. When disturbed by movement — a paddle stroke, a swimming hand, a fish breaking the surface — the water ignites with ghostly blue-green light, each ripple trailing fire. Night kayaking tours operated by local boatmen are the best way to experience this phenomenon. The effect is most dramatic from February through April and is invisible during periods of bright moonlight. No artificial lighting should be brought onto the water.

White Sand Beach Map

Bitaug Beach — Loreto

A pristine white-sand beach on the eastern shore of Dinagat Island in the municipality of Loreto — calm, undeveloped, and lined with coconut palms and indigenous trees reaching to the sand's edge. The water is clear and warm for swimming, and the offshore reef provides snorkelling over relatively intact coral gardens. Bitaug Beach is best reached by habal-habal motorcycle from the Loreto town centre. Overnight stays can be arranged through local homestays, making it an ideal base for exploring the quieter eastern coast of the main island away from the provincial capital.

Rock Formation Map

Hagakhak Rock Formation

A dramatic coastal rock formation on Dinagat Island's shoreline — a series of wave-sculpted limestone pinnacles and arches rising directly from the sea, their bases pounded by Pacific swells. The Hagakhak name is said to derive from a local word for the sound of laughter, referencing the unusual sounds the wind makes passing through the carved rock passages. At low tide, it is possible to walk among the formations and enter several shallow sea caves. The surrounding waters offer excellent snorkelling with diverse reef fish and hard coral formations close to the cliff base.

Crater Lake Map

Lake Bababu

A small, forest-rimmed crater lake in the interior of Dinagat Island — calm, reflective, and surrounded by dense secondary forest alive with birdlife. Lake Bababu is rarely visited and requires a forest trek of roughly two hours from the nearest road, making it an experience for committed nature travellers. The lake's still surface mirrors the surrounding canopy and sky, and endemic birds including the Dinagat bushy-tailed cloud rat's associated habitat makes the forest around the lake of ecological interest. Community guides from nearby barangays lead treks to the lake and maintain the trails.

San Jose and Dinagat Heritage

The provincial capital San Jose is a compact waterfront town with a pleasant baywalk, the provincial capitol building, and a modest heritage district. The town's proximity to the Dinagat Sound offers views across to Surigao City on clear days. The island's history of nickel and chromite mining from the mid-20th century onward is documented in local heritage displays, and the tension between extraction and conservation is central to the province's current identity. The San Jose port is the main arrival point from Surigao City ferries, and the baywalk is the social heart of the capital.

Travel Guide

How to Get to the Dinagat Islands

Fly to Surigao City

The primary access point is Surigao City, served by Cebu Pacific and Philippine Airlines from Manila and Cebu. The Surigao Airport (SUG) is 10 minutes from the Surigao City ferry terminal. No direct flights to Dinagat Islands exist.

Ferry to San Jose

Regular passenger ferries and motorized bangkas depart from Surigao City's San Roque Wharf to San Jose, Dinagat Islands. Journey time is 1 to 1.5 hours depending on vessel and sea conditions. Ferries run several times daily. Sea conditions can be rough during the habagat season (June–October).

Getting Around the Island

Habal-habal motorcycles are the main transport within Dinagat Island. Roads connect the main municipalities but are not always paved. For Sohoton Cove and Basilisa bay, bangka boats are essential — local operators in San Jose and Basilisa arrange tours. The island is small enough to circumnavigate by boat in a single day.

Planning Advice

Sohoton Cove can only be entered at specific tidal windows — plan around tide tables. Coordinate Sohoton and jellyfish lagoon tours through the Dinagat Islands Tourism Office or accredited local guides. Bring cash; ATM availability on the island is limited. Best weather is March through May.
