(Aspen Grove Summit Trail)
The Lame Horse Trail -- also known as the Aspen Grove Summit Trail -- joins the Aspen Grove recreation area (in the North Fork of Provo Canyon) to the Alpine Loop Summit of American Fork Canyon. The trail is narrow singletrack: mostly smooth aspen cruising, but with a good spattering of rocky rooty technical stuff. Elevation gain is 1200 feet over the lower 2 miles, for an average 12% grade.
You can begin the ride either at the Alpine Loop Summit parking lot (GPS N 40° 25.837' W 111° 36.837'), or at the Aspen Grove trail parking area at GPS N 40° 24.350' W 111° 36.307'.
The Stewart Falls Trail and Aspen Grove nature trail also begin at the Aspen Grove lot. These are hiker-only trails. But bring your walking shoes and check out these nice hikes while you're in the neighborhood.
At the top, the trail starts on the east
side of the Alpine Loop summit trailhead. After 1/10th mile, the
Deer Creek South Fork
trail splits off to the left. Keep straight for Lame Horse.
For the bottom end, drive up the North Fork of Provo Canyon. Go to the Aspen Grove trail-parking area. Find the trail on the west side of the parking lot, and follow the "Lame Horse Trail 055" sign. After 0.35 miles, you'll cross a footbridge. Here the trails split. Turn right off the main trail, and begin climbing.
Squirrels, grouse, and deer are common along the trail.
From I-15, take the Alpine-Highland (Timpanogos Highway) exit just south of Point-of-the-Mountain. Go east towards the mountains on UT-92 and continue up American Fork Canyon. There's a $6 fee per car (as of 2018). About 6 miles up the canyon, turn right at the North Fork junction. Drive up to the summit of the Alpine Loop. To reach Aspen Grove, continue 3 miles down into the North Fork of Provo Canyon.From Provo/Orem, drive up Provo Canyon and turn left at the North Fork road (toward Sundance Resort). Drive past Sundance and continue uphill to Aspen Grove.
