Scramble around on red rock with no established trail. This place is fun for the whole family and has amazing scenery. It's also easily accessible and has nearby restrooms and picnic areas to hang out after the adventure.
Snow Canyon is only 15 minutes from St. George, Utah and has so many neat areas to explore. A favorite of mine is to climb around on the petrified dunes. These are located in the middle of the park right off of the road. There is a trail leading from the parking lot for about 1,000 feet to the dunes. Once you reach the petrified dunes, there is no established trail; which leaves you free to wander wherever you want to go.
The Snow Canyon Petrified Sand Dunes is perfect for those who like to scramble across red rock. There is not much exposure, and therefore this area is excellent for the entire family. It rarely snows here (despite the name), so it is accessible year round.
