Named not for winter weather but after a pair of pioneering Utahans named Snow, this overlooked gem of a state park is filled with natural wonders. Hiking trails lead to lava cones, sand dunes, cactus gardens, and high-contrast vistas. From the campground you can scramble up huge sandstone mounds and overlook the entire valley. Park staff lead occasional guided hikes. The park is about 10 miles northwest of St. George, and about an hour from Zion.
