Red Navajo sandstone, capped by an overlay of black lava rock, makes photography, hiking, biking and camping in Snow Canyon a double treat. Early spring and fall use of the park is especially appealing due to southern Utah's moderate winter climate. Two recent volcanic cones were found near the head of the canyon, and the area is popular with rock climbers.

This strikingly colorful canyon is 11 miles northwest of St. George. Facilities include a 35-unit campground, modern rest rooms, hot showers, electric hookups, sewage disposal station, a covered group-use pavilion and overflow campground.

• Hike through interesting geologic features such as lava caves.
