Redrock Mountain Natural Area Preserve is a 640-acre (260 ha) Natural Area Preserve located in Smyth County, Virginia. The preserve is named for the 4,413-foot (1,345 m) Redrock Mountain, which itself is named for its red siltstone cliffs. It supports a number of rare natural features, and two natural community types, including examples of "mountain/piedmont basic woodlands" upon the mountain's slopes, and "rich cove/slope forests" in the preserve's lowlands. Five rare plant species are found on the property, including spring blue-eyed Mary (Collinsia verna), fringed scorpion-weed (Phacelia fimbriata), and Carey saxifrage .
