Entrance to Big Brush Creek Cave

Located high in the Uintah Mountains, Big Brush Creek Cave is a popular destination for cavers. One can drive to the trail anytime there is not snow. The entire Big Brush Creek, along with thousands of acres of snowmelt, flows into the cave during spring runoff. It is the second longest cave in Utah at 4.92 miles and 858 feet deep. Best time to visit would be in summer through fall. If you have snowmobiles winter is a good time to visit. Avoiding visiting during spring dew to high unexpected, deadly runoff.

Ice Structures within BBCC

The cave is part of a larger caving system, and is similar to its brother, Little Brush Creek Cave. Ice crystal formation up to a foot long, and ice structures over 20' long, make this cave an amazing winter wonderland. Inside the cave, passage ways are narrow and cold. Many tunnels are plugged with logs and debris forced into it in past floods. Much of the cave is spent crawling and winding over very tight passages.

Head north on 191 out of Vernal, UT. Go past all switchbacks and past the end of the mine property. Continue to the Red Cloud Loop turnoff. Follow Red Cloud Loop for a few miles. Look for a small turnout with a trail leading from it.
