Most People Don’t Realize An Underground River Flows Right Through Oregon

Did you know that one of Oregon’s most beautiful treasures is actually hiding underground?

Located within the Oregon Caves National Monument, the River Styx is an otherworldly subterranean stream flowing under our state. It breached the surface of the earth thousands of years ago, and in the process caused the caves to form as they did. Not only is this river eerily beautiful, it is also an incredibly special natural wonder. The River Styx is the nation’s first — and only — underground river to be protected by Congress under the National Wild and Scenic Rivers System. Take a look:

During these uncertain times, please keep safety in mind and consider adding destinations to your bucket list to visit at a later date.

The river is named after a mythical Greek location. In Greek mythology, the River Styx formed the border between earth and the underworld.
Due to changes in climate, the water level inside the cave has changed many times over the centuries. It was was once much deeper than it currently is.

The water flows for approximately 0.4 miles underground.
Here, you can see the point where the river flows aboveground. Once the water reaches the surface, it is referred to as Cave Creek.

This water drains into the Illinois River before joining the Rogue River, and eventually reaching the Pacific Ocean.
Visitors to the caves can actually walk over the River Styx by taking a guided tour.
