Mordor DH Trail

Mordor is an expert-level descent from the top of Lonely Mountain to Lower Riverview. At the time of this review, it's reached by climbing up Lonely Mountain, but that will likely change as new trails are finished. It crosses (and sometimes briefly joins) Upper Riverview, Middle Earth, and the Riverview doubletrack. Mordor includes some double-black optional lines.

Mordor is 1.7 miles long, descending 700 vertical feet. It originates on Lonely Mountain just above the Smaug Loop at 6550 feet elevation. Mordor ends on Lower Potatoes just above the Lower Riverview singletrack trail. The expected riding season will be early May through October.

To reach Mordor via Chop'd Coyote and the top of Lonely Mountain, you'll need to climb to 6900 feet elevation. This is the hard way to get to Mordor.

Nice views from the top. Review by Bruce on June 3, 2022.

UVU Trailhead
Most riders get to the Riverview area west-side trails from the UVU Wasatch Campus trailhead. This is found on the far north end of Heber on Highway 40, one mile south of the Highway 32 junction. At the UVU campus entry, turn east (toward the mountain). Go to the uppermost level of parking behind the UVU buildings. Look for the duck-under and kiosk.
The UVU Connector trail climbs uphill from the trailhead to the Upper Riverview (Rivendell) trail after 1.5 miles. On the way, it crosses the easy rides on Lower Riverview, the Riverview Doubletrack, and Middle Earth. (This trailhead is also closest to Frodo's Playground and the beginner skills area trails at Lower Potatoes and Isengard.)

Riverview Trailhead
On US-40 north of Heber, turn east on Highway 32 and climb 1.1 miles. When you see the second entry into Riverview on your left, note the gravel parking area on your right. That's your spot. 

Climb 0.3 miles up the connector, then turn south on Riverview for 1.5 miles to Lonely Mountain and climb up past the Smaug Loop.

South Coyote Trailhead (Construction closure!)
You can get to Mordor from the Coyote Trailhead in the south or the UVU Trailhead in the middle. Connect to Middle Earth for the northbound trip and continue to the Upper Potatoes/Lower Potatoes trail fork. Climb Upper Potatoes to Upper Riverview and turn right. Pedal 0.3 miles to Lonely Mountain and climb one mile to the Smaug Loop. Continue uphill to Mordor, on your right.

UVU Connector and Riverview to Middle Mordor and Lonely Mountain

Climb 1.5 miles on the UVU/Riverview Connector trail, crossing Lower Riverview and Middle Earth. When you reach Upper Riverview, fork left to head north.

After pedaling north and uphill for 1.1 miles, Mordor crosses to start the Middle Mordor trail section. If you don't want to do the short version, keep straight on Riverview and go to mile 1.5 from the UVU Connector -- mile 3 from the trailhead.
Skidder 1 will cross just before the Lonely Mountain trail fork. Continue another 50 feet along Riverview and turn right uphill on Lonely Mountain. Pedal uphill just over one mile, passing both connections to the Smaug Loop. As you reach the top of a small rise, Mordor forks away to your right.

Mordor is an expert-level one-way downhill trail with some double-black optional lines. It consists of three segments: Upper Mordor from the ridgeline down to Upper Riverview, Middle Mordor from Upper Riverview to Middle Earth, and Lower Mordor from Middle Earth to Lower Riverview.
Mordor is 1.7 miles long, dropping 700 vertical feet. That's a respectable rate of descent. Add the many engineered and natural challenges, and it makes Mordor a legit DH.

Upper Mordor is 0.6 miles from the top of Lonely Mountain to Upper Riverview. You'll drop 250 vertical. After the attention-getting drop-in, there are some optional rock stunts and table jumps.
The final bit of Upper Mordor is an insane plunge through tight wiggles in a ravine. Veer left at the bottom to find Middle Mordor on the other side of Riverview.

Middle Mordor has some "cruiser" sections mixed with challenges. There are several A/B splits. Usually you can see the easier route as you approach, but not always. A slower "scouting" run really helps. It's not that hard to climb back up and hit it again.

The ride alternates between open sage with views and maple-oak forest. Some additional stunts and optional lines are still under construction.
When the trail hits Middle Earth, keep left, and after about 30 feet you'll see the entry to Lower Mordor dropping downhill to the right. During this uppermost segment of Lower Mordor (between Middle Earth and the doubletrack), the trail swoops around with few challenges.

Once you cross the Riverview Doubletrack, the trail's character changes. Now you're on hand-built track in the bottom of a wash. There are plenty of alternate lines, and some of them are spooky. Rock challenges are constant, and decisions about where to put your tires come quickly.
At the bottom of Mordor, you'll join Lower Potatoes. Watch for beginners and keep straight as the trail turns south and joins Lower Riverview. You're done!
Almost there. Not quite so steep now, but still pretty tricky.

Getting there!

UVU Wasatch Campus trailhead:  One mile south of the junction of Highway 40 and 32, turn east (toward the mountain) at the UVU campus. Northbound from Utah County, the UVU campus is a couple of miles north of Heber's business area. Go to the uppermost level of parking behind the UVU buildings and look for the step-over and kiosk. The singletrack UVU Connector trail climbs to Lower Riverview at mile 0.2 and Middle Earth at mile 0.7, then continues to the Riverview Trail at mile 1.6.

Coyote Lane trailhead: On US-40 just north of Heber, turn east on Coyote Lane. Just after the road crosses a canal, turn left into the parking lot. The singletrack starts at the northeast corner at the step-over, where you'll also find a repair stand and a kiosk with a trail map. The Coyote singletrack takes you uphill, where you can connect to Riverview after climbing 2.1 miles. You can also connect northbound via the Riverview Doubletrack and Lower Riverview trail or the Sheep Pen and Middle Earth trails. (NOTE:  There is subdivision construction in the Coyote Lane area in 2022, which may affect your access plans. The trails below the Riverview Doubletrack are closed at this time.)

Upper Riverview Trailhead:
From Salt Lake, take I-80 eastbound to Silver Creek Junction (just past Park City). Go south on US-40, past the Jordanelle reservoir and descend past the dam. At the traffic light at mile 14.2 from I-80, turn left on 32 and climb 1.1 miles. When you see the second entry into the Riverview subdivision on your left, note the gravel parking area on your right. That's your spot.
From Utah County, drive up Provo Canyon to Heber. At the traffic light on US-189/US-40, turn left and drive north through Heber. 4.7 miles from the intersection, turn right on Highway 32 and climb 1.1 miles to the parking area as above.

Canal DT trailhead:
Just uphill from the light on highway 32, watch for the canal crossing. Park along the road. Start riding south on the doubletrack just uphill from the canal.

Cutthroat (Highway 32) Trailhead:
Drive up Highway 32 four miles. Look for a gravel road on the right side N40 35.430 W111 23.389. You can park along the road and clamber over the fence near the (locked) gate. Ride uphill on doubletrack and find the singletrack on your left about 100 yards uphill. You'll reach the fork that starts the Coyote Loop 1/2 mile from the highway.
