Across the globe are many hidden underground adventures. Some can be accessed by boat, while others can be accessed by walking or even swimming. These lost worlds underground can be found in various locations, including the United States and other countries such as France. Let’s take a look at some interesting spots.
Discover Underground Worlds in America
Starting with Lost River Cave in Bowling Green, KY, this cave features a large subterranean river with boat access. Boat tours wind through cool limestone passages, and a feeling of historical nostalgia is amidst the serenity.
The Seattle Underground in Pioneer Square, WA, might be one of the most well-known underground spots in the country. You can take part in an underground tour to explore passageways that used to be on street level. Guided walking tours are available, showcasing the former Seattle streets in a hidden world beneath the city.
In Williston, FL, lies the Devil’s Den. It’s a unique sinkhole cavern that’s open to scuba diving and snorkeling. You can’t access it by boat yet, but there are glass-bottom tours available above the spring. It’s like a watery portal to another world.
Hidden Rivers and Caves in France
France is also richly endowed with many hidden caves and rivers. The Padirac Chasm in Occitanie, France, is a massive underground pit with a hidden river. If you visit, you’ll descend into the chasm and then get on a boat to tour the river, drifting past stalactites. It’s one of Europe’s most incredible cave-river locations.
The Labouiche River in Ariege, France, is a subterranean river that winds through prehistoric caverns with scenic views of Magdalenian rock art and other finds hiding in candlelit galleries.
Visit the Gournier Cave in Vercors Massif, France, and you’ll start with a boat launch at the entrance lake, then go into an active underground stream that passes through carved chambers dating back many centuries.
Meanwhile, in Paris, the Canal Saint-Martin features an electric boat cruise through Bastille vaults with an underground view that gives you incredible hidden scenes of the city. The main difference between this one and the others is that it’s man-made.
What Connects These Hidden Worlds?
Hidden worlds come in many forms. They might be underground waterways, caves, or subterranean cities. But they all have in common the feeling of entering a lost world that reveals secret layers of old architecture, ancient geology, or historic finds that have been lost to the ages. Some are natural caves with rivers, and others might be largely man-made.
Along with the hidden worlds mentioned above, there are many more across the globe, including Hidden River Cave in Horse Cave, Kentucky, Mammoth Cave National Park, Rio Secreto in Mexico, and Son Doong Cave in Vietnam. Some are easier to navigate than others. For example, the Hidden River Cave is a pretty wild ride if you choose the expert caving adventure instead of the walking tour. All four include underground rivers or lakes.
It just shows that these hidden worlds exist in every corner of the globe.
