Subterranean River National Park

Hooray for heritage sites - Underground river

Subterranean River National Park. If you’re not scared of dark, tight spaces, then book a trip to Puerto Princesa, Palawan to see the Subterranean River National Park. It is the longest subterranean river in the world, running about 8.2 kilometers—and it’s also one of the rare rivers that flow out into the sea from an inland source.
