Grafton Mesa is the bench above the Virgin River at Rockville, with a network of dirt and slickrock trails that climb onto the mesa, traverse its top, and drop back into the river corridor near the Grafton ghost town site. Like JEM and Wire Mesa, it's primarily a mountain bike destination. Hikers can walk it, but the full trail network is more bike-friendly than foot-friendly in scale, and most hiking parties focus on shorter sections or on the Grafton ghost town approach rather than the full mesa loop.
The ghost town
Grafton is a 19th-century Mormon settlement on the Virgin River that was abandoned by 1944 due to repeated flooding. The townsite is preserved as a ghost town — a few wooden buildings, a cemetery, and the remains of the irrigation system that once supported the community. The site was used as the location for *Butch Cassidy and the Sundance Kid* (1969), where Newman and Redford rode bicycles around the buildings in one of the film's set-pieces. The road to Grafton from Rockville is dirt but passable in any vehicle in dry conditions.
What the trail does
From the Rockville trailhead, the trail climbs onto Grafton Mesa via a series of switchbacks, traverses the top of the mesa, and descends to a viewpoint above the Virgin River and the ghost town. Some routes loop back to the trailhead; others continue to the Grafton ghost town area. Total mileage for the standard loop is around 6 miles with cumulative elevation change of 600 to 800 feet depending on which variations you take.
What you see from the top
Looking south from the mesa, the Virgin River corridor with Rockville and Springdale to the east. The Watchman peak in Zion is visible to the east on a clear day, with Bridge Mountain and the lower Zion canyon walls in the foreground. Looking west, the open desert running toward Hurricane and the Hurricane Cliffs. The mesa sits at a useful vantage for understanding how the Virgin River cuts through the country between Springdale and the lower towns.
Sharing with bikes
The trail is open to both hikers and bikers. Bike traffic is moderate compared to JEM or Bear Claw Poppy; peak season weekends will have steady riders, but weekdays and shoulder seasons can be quiet. Standard mixed-use etiquette applies.
The film history
Grafton's role in *Butch Cassidy and the Sundance Kid* is a real cultural draw for the town and the trail network. The bicycle scene that introduced the song "Raindrops Keep Fallin' on My Head" was filmed at the ghost town. Visitors interested in film history sometimes do the trail specifically to combine the hike with a stop at the ghost town, where interpretive signs note the production history.
Heat and seasonality
The trail is mostly exposed with limited shade. Summer afternoons are hot; the mesa retains heat. October through April is the comfortable window. Spring is the wildflower season at the lower elevations. Fall has the most reliable weather and the cottonwoods along the Virgin River corridor turn yellow in October.
What's around
Rockville has minimal services — the Rockville Inn for lodging, a small market, and not much else. Springdale is ten minutes east for full services. The ghost town can be reached by road in any vehicle. The trail network is the recreation layer above the ghost town and the river.
Where it fits
Grafton Mesa is the trail you do for the views and the historical context — the combination of mountain biking infrastructure, a real ghost town, and the film history makes the area more interesting than a typical Hurricane Cliffs bike trail. For hikers, the shorter approach to the ghost town from the road is more common than the full mesa loop. Pair with a Zion-corridor day or with a Springdale dinner for a complete west-of-Zion experience.
