Lonely Mountain and Smaug Loop

Lonely Mountain is a popular trail on the front (western) side of the Coyote system. On the northern end, it climbs from Upper Riverview. On the south end, it ends on Chop'd Coyote. In the center, Lonely Mountain is joined by An Unexpected Journey. There are several excellent loop ride possibilities.

Lonely Mountain is 2.5 miles long, with an elevation gain of 650 feet when done from north to south. The top elevation is just under 6900 feet, for an expected riding season of early May through October.

Lonely Mountain is also your route to the Smaug Loop (discussed on this page), and is your connection to the top of the expert-level downhill Mordor and the double-black DH Skidder 1.

Two air opportunities on Mordor. Hit one or both. There's a big rock drop on the right and a launching lip on the left a bit further downhill.

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.

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. Take the 0.3-mile connector to Upper Riverview.

UVU Connector and Riverview to Middle Mordor, Lonely Mountain, or Upper Potatoes

Climb 1.6 miles on the UVU/Riverview Connector trail. When you reach Upper Riverview, fork left to head north. After 1.1 miles, Mordor crosses to start the Middle Mordor trail section.

After another 1/3 mile, you'll reach the bottom of Lonely Mountain. Fork right to head uphill to Mordor, or keep left and pedal another quarter mile to reach the top of Upper Potatoes for a descent. The top of Upper Potatoes is 1.7 miles north from the junction of the UVU Connector with Riverview.

Upper Riverview Trailhead to Lonely Mountain

From the Riverview trailhead on Highway 32, pedal uphill on the Riverview trail until you reach the Coyote Loop at mile 0.3 then turn to the right.

At mile 0.4, Sheep Bones forks to the right downhill. If you're headed for the easier trails, descend Sheep Bones for one mile, then continue south on the doubletrack until Lower Potatoes crosses.

At mile 1.6 on Riverview, Upper Potatoes forks to your right on a ridge as the Riverview trail makes a left turn.

Lonely Mountain will be on your left at mile 1.9 from the trailhead. If you're headed for Middle Mordor, it's 1/2 mile further south on the trail at mile 2.4 from the Highway 32 trailhead.

Lonely Mountain joins Upper Riverview to Chop'd Coyote. It is also the access route to ride Mordor, Smaug, or Skidder 1. The trail is two-way.

The bottom of Lonely Mountain begins on the Upper Riverview trail. It's 1.9 miles from the Upper Riverview (Highway 32) trailhead southbound, or 1.4 miles north from the junction of the UVU Connector with Upper Riverview.

The top of Lonely Mountain forks away from Chop'd Coyote at 2.2 miles from Upper Riverview if you're using Chop'd Coyote as your uphill. When descending Chop'd Coyote from the Coyote Loop at the top of the mountain, it's 2.7 miles from Coyote to the Lonely Mountain fork.

There will be frequent views, as very little of the trail is shaded. Here we're looking west at Timpanogos. The climbing is fairly steady but gentle, until you hit a turn. The turns feel very much as though they're intended for DH.

The Lonely Mountain trail is 2.5 miles long with 650 feet of elevation change. The top at Chop'd Coyote is around 6900 feet elevation, which means the trail should be ready to ride around mid-May in most years.
The trail is suitable for strong intermediates. As mentioned, the trail seems to be cut as a downhill flow trail. Most experienced riders will be able to power up and around the turns without much difficulty, but beginners and less-strong intermediates won't find this ride fun.

Around mile 1.1 of Lonely Mountain, you'll reach a flatter saddle area. The entry and exit from the Smaug Loop will be on your right. Not too far past Smaug's connections, you'll reach another trail fork. The trail to the left called Sting angles downhill. (It will return to the West Riverview trail at the Riverview trailhead connector.) Keep right to stay on Lonely Mountain.

Typical turn on Lonely Mountain, as seen in the downhill direction. Everything about this trail screams "downhill."

At mile 1.2 from the bottom of Lonely Mountain -- or 1.3 miles from the upper end on Chop'd Coyote, Mordor has two entries on your right. The choices -- a steep series of spooky drops on the right versus one monster hip-high drop for the left path -- should tell you that intermediates have no business on Mordor.
The Smaug Loop forks away from Lonely Mountain at 1.4 miles from the uphill end, 1.1 miles from the bottom. Smaug is a very easy ride. It's worth a quick trip around the loop, with Smaug rejoining Lonely Mountain just 100 feet from where you entered.
There's a series of turns above the Mordor trail fork, and a long traverse over to Chop'd Coyote. We're looking south as the trail heads to Chop'd Coyote.

The Lonely Mountain trail opens up several loop ride opportunities, both short and long. For intermediate riders, I'd suggest you get to Upper Riverview then climb Chop'd Coyote half-way, then descend Lonely Mountain and Upper/Lower Potatoes.
Smaug
The trail forks to the Smaug Loop are on a flat ridge area around the middle of the Lonely Mountain trail, just downhill from the fork to Mordor.

Smaug is a short loop ride located around the middle of the upper Lonely Mountain trail, just downhill from the top of Mordor. The beginning and end of the loop are only about 100 feet apart. The trail is very easy and quick to ride.

At the far end of the loop, the high-expert Skidder 1 trail forks away.

Smaug is 0.4 miles in length. It can be done either direction and is gently uphill as you ride away from Lonely Mountain. A counterclockwise ride puts the banked turns of the southern side of the loop on the downhill.

The trail is a dirt bench-cut in an area of sage and oak brush. There's only about 50 feet of elevation gain as you pedal away from Lonely Mountain.

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.)

Trailhead options!

UVU Wasatch Campus Trailhead: One mile south of the junction of Highway 40 and 32 (a couple of miles north of Heber), turn east (toward the mountain) at the UVU campus. Go to the uppermost level of parking behind the UVU buildings. Look for the duck-under and kiosk. A singletrack trail climbs 1.5 miles to the Riverview Trail.

Wile E Canyon trailhead: The Wile E Canyon trailhead is located on the southern side of Highway 32, just over 4 miles from US-40. It's 1/10th mile east of the old Cutthroat trailhead (see below). There's room for about 8 cars here. From the parking lot, a connector trail takes you 120 yards uphill to the Wile E Canyon loop. To get to Beep Beep (or the Coyote Switchbacks or East Riverview), turn right at the trail fork, keep right at the next fork, then turn left onto the Coyote Riverview Connector trail as you approach the gravel road.

Coyote Riverview Connector trail (old Cutthroat): You can still connect through the old Cutthroat trailhead, although there's no longer a parking area here. For example, if the crowds have forced you to park where construction workers leave their vehicles along Highway 32, you can pedal to the gravel road to the new golf course leaves the highway, four miles east of US-40 and just east of the big rock-wall road-cut.

Puddy Tat parking: On Highway 3 around three miles from US-40, watch for a dirt road turning to the right in a huge sage meadow. There are a couple of buildings across Highway 32 at this spot. The parking spot is just through the fence, with a connection to Puddy Tat on the eastern side of parking. (This spot was still being worked on at the time of my review.)

Riverview trailhead: From US-40 just south of the Jordanelle reservoir, turn east at the traffic light onto Highwat 32 (at mile 14.2 from I-80 if you're coming from the north). On Highway 32, climb 1.1 miles. When you see the second entry into Riverview on your left and a road under construction to your right, the Riverview Connector trail starts on the uphill side of that road just after it leaves Highway 32. (In 2025, there's no longer protected parking here. It's unclear whether the trailhead will be restored when construction is complete.)

Coyote Trailhead: The southern Coyote trailhead has been lost to subdivision construction. Access to the southern side the trail system is in limbo, but some riders find their way through the construction zone by pedaling up the gravel Coyote Canyon road.

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.
