One of the longest navigable underground rivers in the world, with a stretch that flows straight out to sea inside a cave

Declared in 1999 and one of the New7Wonders of Nature chosen by international public vote in 2012, the Puerto Princesa Subterranean River is one of the longest navigable underground rivers in the world, with a stretch of over 8 km flowing straight out into the South China Sea within a limestone cave system — a direct underground river-to-sea connection extremely rare at this scale.
