Just five miles southwest of Zion National Park, Rockville (no services) seems like an extension of Springdale. There are a few old buildings, but otherwise it's mostly housing. The bicycle scene in Butch Cassidy & the Sundance Kid was filmed in the nearby Grafton ghost town. You can wander freely around the restored 1886 brick meeting house and general store, and a nearby pioneer cemetery. A few pioneer log homes stand on private property.
Fourteen miles west of Springdale, the next little community is Virgin, with the turnoff to Kolob Terrace Rd and a couple of trading posts. Be sure to mind your manners – in 2000, the Virgin council passed a law requiring every resident to own a gun (fine $500).
West of town, a 1.5-mile gravel-and-dirt road leads south to La Verkin Overlook. Stop for a fantastic, 360-degree view from Zion to the Pine Valley Mountains.
