East of Hurricane and southwest of Rockville, the 7.4 mile Wire Mesa Loop offers mountain bikers flowing, technical singletrack along with exceptional views. It is similar to nearby Gooseberry Mesa, but easier and has only 430 feet of elevation change. It can be ridden in either direction, which are both good.
To reach the Wire Mesa trailhead from Hurricane, head east on SR59 for 14 miles passing Apple Valley (watch for the Gooseberry Mesa sign). Turn left heading northwest on the signed Main Street (aka Smithsonian Butte Backcountry Byway) for 7 miles. Turn left heading north on unsigned road access road to the trailhead parking lot.
In the past, it had been popular to stay in Springdale and use the Rockville entrance up to Wire Mesa. It’s not very popular any more (keep reading). To reach the Wire Mesa mountain biking trailhead from Springdale, head west to Rockville. In Rockville, turn left heading south on Bridge Road (small sign on small road) for 0.25 crossing the bridge over the Virgin River. Turn right heading west on Grafton Road for 1.5 miles. Turn left on Smithsonian Butte Road, which heads up the mesa. While this road was quite passable a decade ago, the rains have been pretty harsh on the road quality and it is now quite hazardous. Pretty quickly, the dirt road degrades into extreme 4WD with steep, off-camber rocky sections requiring advanced offroading skills for a mile to the mesa top. After a total of 1.8 miles on the Smithsonian Butte Road, turn right heading north on unsigned trailhead access road to parking lot.
Overall, Wire Mesa Loop is the 73rd most popular mountain bike trail of all 73 mountain biking rides in Utah.
