A 30–45 minute bangka ride through the Philippines' largest mangrove forest ends at a jade-green lagoon walled in by jungle-covered limestone hills. The floating pontoon has a wooden diving board, and paddling a SUP or transparent kayak across the glassy water is the signature Siargao postcard moment.
A full-day expedition (about two hours by boat from Siargao) into a labyrinth of limestone lagoons, glowing caves and hidden lakes on Bucas Grande Island. Small paddle boats thread through Hagukan and Magkukuob caves, and in season you can swim among thousands of harmless stingless jellyfish in the sanctuary lake.
A long-established tour office on Tourism Road running private and joiner island-hopping trips to Naked, Daku and Guyam plus land tours across the island. Their signature private tri-island day (10am–4pm) includes snorkeling stops and a generous grilled seafood lunch on the beach.
The classic motorbike-or-van loop up Siargao's east coast: swim in the gin-clear natural infinity pools at Magpupungko in Pilar, swing over the palm-lined Maasin River, and stop at the Coconut View deck where thousands of palms roll to the horizon. Most tours finish with Secret Beach or Pacifico's empty sand.
A turquoise lagoon ringed by jungle-covered limestone hills, reached by a gorgeous 30–45 minute bangka ride through the largest contiguous mangrove forest in the Philippines. A two-storey pavilion floats in the middle with a jumping platform, kayaks and paddleboards for hire. The water shifts between blue and green depending on the light and is calm enough for even hesitant swimmers.
