|Lookout Peak to Big Mountain Loop|
This loop ride is for advanced and adventuresome riders. The ride
climbs Big Mountain Pass, then up Big Mountain itself. It includes a
brutal climb, a section of rough root-strewn tech riding, and a
ball-bearing-slippery steep descent.

|The trail rolls around the ridge that connects Big Mountain to Lookout Peak, skirts the top of Emigration Canyon, then drops down to Affeck Park from the top of Killyon Canyon. The route described here is 15.4 miles, with altitude change of 2500 feet, reaching a peak altitude of 8600. Up-and-down riding on the ridge brings the total vertical to around 3500.|
|Update: The climb from Big Mountain is reported to be loose and washed out, so you can expect to hike your bike a bit. The section from the GWT over to Lookout Peak is seriously overgrown with trailside brush and small trees. Until some serious trailwork is done, this route should be considered only by those who are looking for new trail and a real challenge.|
Once you've climbed above 8000 feet, you'll spend 7 miles riding along ridgeline at high altitude as you loop around the border of a huge deep valley -- Mountain Dell Canyon. You'll be able to see into Parley's Canyon, the Park City area, Morgan Canyon, and Emigration Canyon. Most of the ridgeline ride has fabulous open views. This is a very pretty ride, but is only for those with good skills, strength, and altitude acclimatization.
|Riding around the loop counterclockwise, the tech factor
gets progressively tougher. The first 3.5 miles is the Mormon
Pioneer Trail, and it's relatively easy. The climb isn't too tough and
the trail is broad and smooth. You'll be riding in forest of box elder,
maple, and oak, with occasional groves of aspen. Elderberry, chokecherry,
and fern are found in the understory.
The Mormon Pioneer Trail is the uphill route to Big Mountain Pass. Near the top, giant ferms grow among maples and aspen.
|The Great Western (GWT) up Big Mountain is narrow and steep
with tight switchbacks -- you'll gain 800 feet in 1 mile. Only the best
can ride this without an occasional dab or brief push-a-bike. At the top,
look over the valley below you.
Looking towards Emigration Canyon, we see bushes of serviceberry (hawberry). These provided a tasty treat for a hungry biker!
|You're going to ride around the rim of this valley. Any fork that takes you away from the rim is the wrong way. The trail turns north and rolls along the ridge for 2 miles on easy but narrow singletrack, then 2 miles of occasionally rocky doubletrack. You're riding on open wind-swept ridge with occasional groves of aspen. The views in this area are fabulous!|
Panoramic 120-degree view as the trails circles the ridgeline from Big Mountain (L)
to where we're standing, then on to Lookout Peak (R). Below us is Mountain Dell Valley.
|The GWT singletrack around the north end of the valley is upper-intermediate technical, with occasional short tough sections. Be sure you don't miss the critical turn that takes you up the ridgeline, then over the saddle to the east side of Lookout Peak. Here you'll encounter a mile of very narrow up-and-down technical trail with roots and tree trunks to hop over, while small trees and brush drag at your handlebars. Much fun!|
|Photo above: While most of the ride is on exposed ridgeline, you'll slip through groves of trees. On the side of Lookout Peak, there's a long stretch of trees that's pretty rad.|
|Descending from Lookout Peak requires good rock-surfing
skills, as this steep trail is littered with skittery round boulders. Roll
over conglomerate outcrops, keep your butt back, and work your brakes
carefully. Despite the 1000 ft per mile rate of descent, the trail is very
rideable. Intersecting a trail at the top of Killyon Canyon, you turn left
to drop down to Affleck Park to complete the loop.
The wind can get pretty intense on the ridgeline. Note the scoured upwind (west) face, with lush downwind side.
|Getting there, Pioneer Trail parking area: On I-80 in Parley's Canyon, take
the Little Dell Recreation Area exit. From the exit, drive uphill 4.1
miles, then park on the right side of the road near the outhouse at GPS N
40° 47.996' W 111° 40.750'. The trail begins on the opposite side of the
road, just downhill.
Affleck Park trailhead: Drive another 0.8 miles uphill, then turn left and descend to Affleck Park. Keep right and proceed uphill to the north end of the park, and find the sign indicating the Mormon Pioneer Trail. (The return trail is across the creek.) Subtract 1 mile from the mileage below when riding the trail.

Little Dell trailhead: At mile 2 after exiting the freeway, turn right into the Little Dell recreation area (fee required). Roll down to the trail parking lot near the water. Trail begins paved at GPS N 40° 46.622' W 111° 41.317', then turns to cinder as you pass close by a picnic table. Add 1.9 to the mileage below. See the Pioneer Trail page for additional details.
