Glide into Puerto Princesa’s UNESCO-listed Underground River by paddleboat and watch limestone caverns unfold like a page of geological history. This half-day excursion pairs mangrove approaches and karst geology with practical tips for planning permits, timing, and what to pack.
More ways to explore the area's outdoor wonders
You step off the jeepney onto humid earth and a strip of concrete that leads to Sabang’s wharf where the jungle leans close to the shoreline. The sound of the sea is a steady exhale; beyond the mangroves a line of banca boats rocks in the blue-green water, each with a guide who knows the rhythm of the river and the cave. Tickets and permits are checked, life vests fitted, and the group pushes off in a wooden paddleboat that will carry you into one of the Philippines’ most elemental landscapes.
