Surrounded by 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 Utahs moderate winter climate. Two recent volcanic cones are found near the head of the canyon. This strikingly colorful canyon is 11 miles northwest of St. George.
Take exit 6 and go west on St. George Blvd. until Bluff Street. Travel north on Bluff (which is also SR18) about one mile to Snow Canyon Parkway, turn left, go six miles to Snow Canyon Drive, turn right.
