J.E.M. Trail

The J.E.M. Trail is found just west of the town of Virgin near Zion National Park. Named for trailblazers John, Ellen, and Mike, this trail offers high-speed desert cruising and a cliff-side ride along the Virgin River.  Except for one dangerous switchback (which you can walk), it's an easy technical ride.

Most riders do this trail as an out-and-back or as a shuttled ride top-to-bottom. Others do the JEM as the middle portion of the 21-mile loop using Goulds and Hurricane Rim

Then there's the old classic JEM Loop, which is 12.9 miles in length with 800 feet of altitude gain. The first half of the classic JEM loop is uphill doubletrack; the last 6.2 miles is downhill singletrack.

View up the wash, about 2.5 miles into the classic loop ride. The wash here has a hard bottom, and is fairly easy to ride.

Aerobically, this trail is fairly easy. The first 300 feet of altitude gain is imperceptible as you ride the double-track towards the mesa. Once you reach the base of Gooseberry Mesa, there's a bit of up-and-down, but all doable in the middle chainring.

The trail is a fun ride, and definitely worth doing. The views into the chasm of the Virgin River are awesome, and the high-speed singletrack descent is a blast.

The "badlands" and the alternating bands of red and white of Gooseberry Mesa are mudstone of the Moenkopi Formation, laid down during the early Triassic (about 240 million years ago). As the ocean receded, gravel and shoreline deposits formed the hard Shinarump conglomerate, which begins the cap of the mesa.

Near the top of the ride, the trail passes by a fruiting yucca.

There are trailheads and parking at each end of the trail. The bottom end is just off Highway 9 on the way to Zion National Park. The top end is on Highway 59 just before Gooseberry Mesa.

For out-and-back or one-way riding, the trail is so well-marked that I don't think you need a riding guide. Just follow the signs.

Near the top of the trail, looking north. We'll drop into the valley.

Classic JEM Loop clockwise:
From the lower trailhead off Highway 9 (see below GPS N 37 12.029' W 113 13.089', altitude 3320 ft.), backtrack 0.2 miles and turn right on the main gravel road. 

At 2.1 miles, you'll drop through a big wash. Just a bit further, at 2.3 miles, you turn left off the main road into a shallow wash, or the doubletrack 0.1 mile further on (GPS N 37 10.726' W 113 14.326'). The wash and road will cross a number of times, so it doesn't matter which one you take.

Jackie grabs a little bit of shade as I stop to take a trail photo.

A singletrack branches off the wash at 2.9 miles, dumping back onto an intersection of the road and the wash at 3.0 miles. You'll see an old corral and a gate just up the road. From here, I suggest you take the road, because the wash gets soft (hard to ride), with some confusing branches.

At 4.1 miles, the trail crests at the top of the big wash. (There are a few stock watering tanks here.) Drop down into the wash and head uphill. Follow the road as it dips into and out of the wash. At 4.4 miles, the road forks. Go RIGHT (west). At 5.25 miles, you'll encounter a gate as the road passes around a sandstone canyon on your right.

High-speed cruising on JEM's middle section, heading northeast.

At 6.7 miles, the singletrack branches off on your right (GPS N 37 08.637' W 113 14.511', altitude 4160 ft). A rockpile marks the trail. Kowabunga! It's cruising time. Except for a couple of short technical sections, from here you can fly through the desert at motorcycle speeds.

At 7.1 miles, the trail walks down the cliff with a steep technical switchback. There's some injury potential here. But it's just a short walk. At 8.4 miles, the singletrack crosses the main road.

At mile 11.4, the Hurricane Rim trail forks off on the left, N 37 11.261' W 113 13.862'. Keep right. (Option: take Hurricane Rim to China Wash, then turn south to connect again to JEM about 1.5 miles uphill from where you forked onto the Rim, then retrace back to the fork. Adds about 5 miles to the ride. See GPX or MPS file.)

Jackie investigates the edge of the wash as it deepens to a 30-foot chasm. July 7, 2001.

At mile 11.5, the trail drops into the wash. Ride across the rock, and spot the continuing trail on the far side of a second wash. (If you're afraid of heights, you can bail out on the doubletrack road here to avoid riding along the Virgin River Gorge.) You'll ride a mile along the edge of the Virgin River, as it cuts a deep canyon. Then the trail takes you back to the parking area.

View into the Virgin River from the trail. The river is swollen with last night's rains.

Getting there: From I-15 north, take the La Verkin exit on UT-17. From the south, take the Hurricane exit on US-9 and go through Hurricane towards Zion National Park. At the junction of US-9 with UT-17, turn east towards Zion. 4.8 miles after the turnoff, turn right (south) on a gravel road signed "Sheep Bridge Rd." 0.5 miles later, you'll cross over the Virgin River. Just uphill is a cattleguard, then a doubletrack on your right 0.1 miles after the bridge. Take the doubletrack 0.2 miles to a turn-around overlooking the Virgin River. The singletrack is at the end of the turn-around. For the classic (old) JEM loop ride, head back on the dirt road. For the Hurricane Loop, ride up JEM to the Hurricane Rim trail.
Upper JEM trailhead: In Hurricane, turn south on US-59 (towards the Grand Canyon). Drive exactly 5 miles uphill. Turn left on cindered doubletrack right as you approach the base of Gooseberry Mesa. Drive another 0.3 miles to the parking area. N 37 08.329' W 113 14.527'
