Forbidden Trail
Includes More Effort

The Forbidden Trail is part of a popular route from Alpine to Draper. It can be part of a long loop ride in the mountains north of Alpine when combined with Three Falls Fort Canyon plus either Vista Ridge and Stoney Way or Bodily Harm . It's intermediate in tech requirement, with around 700 vertical feet of climbing from Alpine to Fort Canyon. See the area overview page for links to other area trail pages .

Trailhead info
On Alpine's Grove Drive, head north to the second T intersection (where a right turn would take you across the bridge into Lambert Park). Instead, turn left on Alpine Cove Drive. At the 4-way intersection, turn left. As Alpine Cove Drive turns downhill, turn uphill on Aspen Drive. It will turn to the Three Falls Lane road. As the larger road veers left, keep straight onto a smaller dirt road and quickly find the trail on your left. (Alternatively, continue uphill to the Schoolhouse Springs trailhead and take the connecting trail downhill to Forbidden. See the map.)

At the first T intersection when northbound on Alpine's Grove Drive, turn left. After 1/10th mile, turn left again. Go 1/10th mile and turn right on Savannah Circle, then right into The Ridge trailhead. Take Stoney Way northeast 1/2 mile. Keep right as you reach Bodily Harm and traverse another 0.2 miles. Hike-a-bike up to the road and cross to find Forbidden on the other side.
From the Fort Canyon Ranch Trailhead in Alpine's Fort Canyon, you can reach Forbidden by taking the Three Falls Fort Canyon trail. Keep left as Vista Ridge , Last Chance , and Bodily Harm fork away on your right. Descend into upper Fort Canyon, cross the paved road, and climb uphill about 1/10th mile. At mile 2.4 from the Fort Canyon Ranch trailhead, fork to the right on Forbidden.

On Alpine's main street, continue north until the road turns right at Fort Canyon, then watch for a small paved Heritage Hills (North Point) trailhead on your left in about 1/4 mile. Climb up through Heritage Hills until you reach Stoney Way and turn right. Traverse the hillside northbound for 1.5 miles to reach Forbidden across the Fort Canyon Lane road.

Heading uphill toward Lone Peak on the lower segment of the trail, near Schoolhouse Springs in Dry Creek Canyon.

The Forbidden trail, finished in late summer 2018, lies to the northeast of the Bodily Harm (historic Neph's Lake) route. It's 2.6 miles long, running from Alpine Cove to the Three Falls trail in Fort Canyon. The trail begins on the Schoolhouse Springs (Hammagog) road just after it leaves the Three Falls subdivision road.

A connector from the small Lone Peak (Schoolhouse Springs) trailhead joins Forbidden one switchback uphill from the creek. There is currently very scant parking at the bottom of Forbidden, so you'll likely need to use the Schoolhouse Springs trailhead or find roadside parking away from the construction area if you're driving into the area.

View across upper Fort Canyon at the highest point of the Forbidden trail at around 5900 feet elevation, looking south.

Across from lower Forbidden on the Three Falls Lane road is the combined Stoney Way and Bodily Harm trails heading southwest.

The upper end of Forbidden is on the Three Falls trail to Draper, just east of the bridge over the big ravine and above the Three Falls Lane road. A left turn downhill takes you to Three Falls Fort Canyon , while a right turn takes you toward Draper.

At mile 0.9 of Forbidden, the More Effort trail (see below) joins on the left as Forbidden turns hard to the right.
The trail hits crosses a road at mile 1.7 from the bottom. The continuing trail is at the break in the fence just across the road. This is the highest elevation of the Forbidden trail. The trail now begins dropping into Fort Canyon. It will join the Three Falls trail in another 0.7 miles. Here a left turn takes you down and across the road, and a right turn takes you across the bridge on the Three Falls trail toward Draper.

Typical stretch of trail above Alpine Cove. Exposed trail winding back and forth across the mountain between tight turns.
In the downhill direction, around mile 1.6 from the Three Falls trail fork the Forbidden trail settles into a series of long traverses between switchback turns as it slowly sheds elevation.
At mile 1.7, keep left on a turn as More Effort joins the middle of that turn from your right.
As you get close to the bottom, at mile 2.5, a trail joins from the left. This is the connector to the Lone Peak trailhead uphill. If you continue straight, it will take you down another couple of turns, through the creek, and you'll join the trailhead road at mile 2.6.

I really like the Forbidden trail as a climber. It's less steep than Bodily Harm . From Alpine Cove to Three Falls, you'll do much of the elevation gain on the traverses. They work a lot better uphill than downhill, I think. The trail has 600 feet of elevation gain. The surface is smooth and turns have a generous radius. It's a fairly easy trail to pedal.

A loop ride from Alpine Cove using Forbidden, Three Falls Fort Canyon and Bodily Harm will be 5.5 miles with 1000 vertical feet of climbing.

The new origin of More Effort. Seen as if climbing Bodily Harm. Bodily Harm is a 180 degree turn to the left; More Effort is straight ahead.
More Effort is a connecting trail between Bodily Harm and Forbidden, 0.6 miles in length. Starting from Bodily Harm, it will cross the Three Falls Lane road and climb 150 vertical feet to join the Forbidden trail.
The trail can be used as the bottom of a long loop from above, joining Bodily Harm and Forbidden. Or for beginners, it can be the top of a short loop starting from Alpine.
When climbing Bodily Harm, the fork for More Effort comes at mile 0.5, on the right. (180 degrees right continues uphill on Bodily Harm.) After leaving Bodily Harm, the trail will reach the Three Falls Lane road in 1/10th mile. Go uphill slightly to turn into the continuing trail.

Getting there, Fort Canyon Ranch Trailhead: As you drive into Alpine on Main Street, keep straight at all intersections until you reach 800 North. Then, just as Main Street turns to the right and becomes Heritage Hills Drive, fork left on Fort Canyon Road to continue north. 0.9 miles later, turn right just before the Three Falls gate. Quickly turn left into the parking lot for the Three Falls Farm trailhead. Pedal up Three Falls, crossing upper Fort Canyon, to reach the upper end of Forbidden.
Heritage Hills (North Point):  Shortly after you veer to the northeast from Main onto Heritage Hills Drive as above, spot the small parking lot on your left and turn in. Pedal up through the subdivision and find Vista Ridge/Heritage Hills heading uphill. If you're heading for the top of Forbidden, keep left. For the bottom of Forbidden, go right for 1.5 miles.
The Ridge TH (Stoney Way and Big Hollow):  At the T intersection of Grove Drive, turn left and follow the road to another T intersection. Turn left, then right on Savannah Circle. As it approaches the mountain the trailhead is on your right. Take Stoney Way 0.7 miles northeast to find Forbidden on the opposite side of the Fort Canyon Lane road.

Facilities: bathroom at Fort Canyon trailhead, bathrooms at Lambert Park trailheads. (No services at Schoolhouse Springs, The Ridge (Big Hollow), or Heritage Hills trailheads.)

Getting there, Alpine Cove - Schoolhouse Springs:  Instead of turning left on Fort Canyon Road, stay on Heritage Hills Drive. Turn left uphill on Grove Drive. At the T intersection (where a right turn would take you across the bridge into Lambert Park), turn left on Alpine Cove Drive. At the 4-way intersection, turn left. As Alpine Cove Drive turns downhill, turn uphill on Aspen Drive. It will turn to the Three Falls Lane road. As the larger road veers left, keep straight onto a smaller dirt road. There's a spot to your left just after you leave the main road. That's the beginning of the trail.

To start from the formal trailhead, go 1/4 mile uphill and park at the Lone Peak trailhead. Go all the way up to the "Lehi" gate and turn left to get on the singletrack that dips through the creek. Keep left and descend on the trailhead connector. You'll find a connection to Forbidden on the right. To reach Bodily Harm, you'll need to coast all the way down to the raised Three Falls Lane road, then crawl up and over it to find Bodily Harm on the opposite side.
