Sohoton Cove Samar: Swimming with Jellyfish in a Hidden Lagoon

There is a lagoon in the Philippine islands where jellyfish drift through emerald-green water like luminous ghosts, and where the ceiling above you is a karst cave draped in stalactites and ferns. You swim among the jellyfish, millions of them, none of them capable of stinging you, in water so clear and still that you can see your own shadow on the white sand floor six meters below. Above the caves, the limestone cliffs are so densely forested that the light comes through filtered green, cathedral-like.

This is Sohoton Cove, in the Bucas Grande Islands off the coast of Surigao del Norte, accessible as a day trip from Siargao Island or as part of a longer Mindanao and Eastern Visayas itinerary. It is consistently rated one of the most extraordinary natural experiences in the Philippines, and among all the places on this list, it may be the one that most reliably exceeds expectations.

Where Is Sohoton Cove?

Sohoton Cove is located within the Bucas Grande island group in Surigao del Norte, approximately 2.5 hours by boat from General Luna on Siargao Island. The cove is part of the Siargao Island Protected Landscape and Seascape. Access requires booking a licensed tour boat from Siargao. A Sohoton Cove and jellyfish sanctuary tour from Siargao is the standard format, departing early morning and returning late afternoon, often combined with stops at Naked Island, Daku Island, and Guyam Island in the Siargao island hopping circuit.

The Jellyfish Sanctuary

The jellyfish that have made Sohoton famous are Mastigias papua, a species of lagoon jellyfish found throughout the tropical Pacific. What makes Sohoton's population special is not the species but the environment. Trapped in a lagoon system with no significant tidal flushing and no natural predators, the jellyfish have evolved over thousands of years to lose most of their stinging capacity. The result: millions of jellyfish that pulse and drift around swimmers with complete indifference, occasionally making gentle contact that feels like a soft brush on your skin. Nothing more alarming than a leaf touching your arm.

The jellyfish range from thumbnail-sized juveniles to adults the size of a dinner plate. They move with the languid pulsing characteristic of their class, neither fast nor directed, simply existing in their improbable millions in this isolated lagoon. The water they inhabit is bright green from algae and completely calm, with a temperature warmer than the open sea outside. Entering it feels like entering another world.

The Caves

The jellyfish lagoon is accessed through a cave passage, low enough that boats cannot pass in many tidal conditions, requiring visitors to swim or wade through approximately 30 meters of tunnel before emerging into the sunlit lagoon. The passage is lit at times by filtered light coming through the ceiling, creating effects of extraordinary beauty. On the walls, freshwater drips have built small stalactite formations alongside tropical ferns and mosses. Beyond the jellyfish lagoon, the Sohoton complex includes several larger caves with dramatic geological formations. One cave opens to a hidden lagoon accessible only by diving under a limestone wall.

What to Expect on the Tour

A standard Sohoton Cove tour from Siargao runs approximately 10-12 hours and typically includes: 7:00 a.m. departure from General Luna by speedboat, 8:30 a.m. arrive Bucas Grande and transfer to smaller pumpboats for cave access, 9:00-11:00 a.m. cave exploration and jellyfish sanctuary swim, lunch, then 12:00-3:00 p.m. return journey with island hopping stops, and 4:00-5:00 p.m. return to General Luna. The tour price typically runs PHP 1,500-2,500 per person for a shared boat. The government-mandated entrance fee is PHP 250-300 per person.

Important Practical Information

Tide timing is critical. Access to the jellyfish lagoon depends entirely on tidal conditions. The cave entrance is impassable at high tide. Tours are timed to hit the sanctuary during the 2-3 hour window around low tide. Always ask your tour operator what tidal timing they are planning and whether jellyfish sanctuary access is guaranteed on that day.

Seasonal jellyfish availability. Jellyfish populations at Sohoton vary seasonally. Numbers are typically highest from March to October. Between November and February, populations can be significantly reduced and some visits find the sanctuary largely empty of jellyfish. The caves and overall scenery remain extraordinary regardless.

No sunscreen in the water. This is non-negotiable. Chemical sunscreen kills jellyfish and disrupts the sanctuary ecosystem. The no-sunscreen rule is strictly enforced. Use reef-safe mineral sunscreen on your face and apply it before boarding the boat. Wear a rash guard for UV protection in the lagoon.

Why Sohoton Stays With You

The Philippines has no shortage of extraordinary natural experiences. What makes Sohoton different is the combination of elements: the cave passage, the luminous lagoon, the jellyfish that bump softly against your hands, the green light filtering from above, the silence that exists in a karst cave with jellyfish in the water and stalactites overhead. It is the kind of place that you describe to people and watch their face carefully to see if they believe you. They mostly do not, until they go themselves. Go yourself. Bring reef-safe sunscreen.
