Did you know the Philippines has a navigable river running underground for over 5 miles or 8 kilometers? The Puerto Princesa Subterranean River on Palawan winds through a cathedral-like cave system before emptying straight into the sea. It's a UNESCO World Heritage site and was voted one of the New 7 Wonders of Nature.
