RV rental Sinks Canyon State Park, WY: Motorhome rentals, camper van rentals and more

For years, a deep mystery hid in the waters of the park, as the lake would dissolve into low levels underneath the canyons at the area in the park known as “the Sinks” without leaving a clue as to where they'd gone. And although all suspicions pointed towards a section of the lake known as “The Rise,” there was no way to know for sure. This mystery was solved in an unusual way when the United States Geologic Service conducted a bright red dye test. Pouring fluorescent dye into the rushing waters, they eagerly waited with scientific instruments at the Rise. A full two hours later it was confirmed — the water was undergoing an exciting quarter of a mile journey underneath the caverns just to reappear at the Rise. This uniquely bizarre phenomenon is just one of the reasons camping at Sinks Canyon State Park is so popular. While at the park, don one of the provided headlamps and your favorite pair of hiking shoes for the breathtaking guided tour into Boulder Choke Cave. You'll have the opportunity to view the Popo Agie River (which roughly translates to mean "gurgling river") while inside the cave. Have fun exploring geological treasures, numerous chambers, and more on this one-of-a-kind experience. Over seven diverse hiking trails are begging to be explored by Sinks Canyon State Park campers, from the one-mile-long Popo Agie Nature Trail surrounded by aspen groves and sagebrush meadows, to the four-mile pine-infused Canyon Trail.
