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

Nature is full of strange and wonderful oddities, and underground rivers are definitely up there amongst the most remarkable. How can a river flow underground? Usually, this unique phenomenon occurs when the riverbed isn’t actually the surface of the earth, but the waters of the river flow into a cave system or are otherwise directed through an underground passage.

It’s a little-known fact that one of Massachusetts’ most scenic rivers actually flows underground!

Bass River Beach (also known as Smugglers Beach) is an amazing place to enjoy an idyllic Cape Cod afternoon. The sand is soft and clean, there are showers and restrooms that are open to the public, and even a beautiful boardwalk area with snacks available for purchase. During the summer months, stop by for their famed sand-sculpting competition or to watch hang gliders float over the glittering waves.

Massachusetts is full of surprises, and this beautiful underground river is just one of many. For more incredible natural sites across the state, check out these 10 spots that will bring out the explorer in you.
