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 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.
A 1.8-kilometre raised wooden walkway zigzagging through the heart of the Del Carmen Mangrove Reserve — the largest contiguous mangrove forest in the Philippines and a Ramsar-listed wetland. Herons, kingfishers, monitor lizards and armies of crabs go about their business below the planks, and the light at golden hour is extraordinary. It's Siargao's most peaceful major attraction, and one of its least visited.
