Rivers have attracted travelers for their beauty, their bountiful supply for fishing, their fun and engaging rapids for water rafting, their leisure flow which makes for fun days of tubing—the list goes on and on. However, for most, a river experience is usually above ground. And that’s a shame because the world is filled with beautiful underground river systems that you can explore. We’ve put together a list of subterranean rivers from all over the world that provide incredible travel experiences through a dark world that’s both stunning and mysterious.
1. Rio Secreto, Mexico
There’s nothing quite like Rio Secreto in the world. This underground river, located just a 13-minute drive outside of Playa del Carmen, features turquoise waters and stunning stalactites and stalagmites.
