Mercer Hollow

The Mercer Hollow trail lies on the southern slope of Traverse Mountain in a shallow valley called Mercer Hollow. It's just across Traverse Ridge from the Corner Canyon trails. This intermediate-level trail was cut in 2016 with the best trailbuilding techniques to maximize fun and sustainability. Combined with a reworking of Eagle Crest and South Maple Hollow, this begins Draper City's development of their southern trail system.

On these south-facing slopes at foothill altitude, the riding season is mid April through November. But if you're planning an extended ride in early spring, the trails on the north side of Traverse Mountain (such as Rush, Ann's, and Canyon Hollow) may still be muddy when this trail is dry. The sample ride listed below uses only trails on the southern slope.

View over my Rocky Mountain's handlebars as the trail drops off Suncrest Drive.

The trail is 2.0 miles long, about half singletrack and half doubletrack with 500 feet of elevation change. Both ends are on the east side of Suncrest Drive. The upper end is where the sort-of-flat terrain of Traverse Ridge gives way to the slope of Mercer Hollow. There's no formal parking at the top, but riders can find a spot nearby where they can wedge their vehicle between the road and the oak brush.

The downhill end is just east of the Mercer Hollow subdivision. There's a wide spot off the road with enough room to leave a car or two if you're using the trail's bottom as your starting point. Or if you're doing shuttled laps.

Looking east. The notch in the mountains is American Fork Canyon.

At the top, the Mercer Hollow trail begins on the east side of Suncrest Drive at 5950 feet elevation, 1/2 mile downhill from the 4-way stop at the summit. (See the directions near the page bottom.) Look for the fire hydrant just below the new eastbound road (under construction in 2016) on Traverse Ridge. This is about 100 yards uphill -- and across the road -- from the eastern end of the Eagle Crest trail. 

Note the swoops on the steep side-slope ahead. Yes, these are great fun. But they also keep water from channeling on the trail and washing it out.

The first 1.1 miles is swooping twisting singletrack that drops 300 vertical feet as it descends southbound. but it won't be 100% descending. Most of the uphill bits are very short grade reversals to help the trail shed water, and you'll just roll right over them. But there are a couple of spots where you'll need to pedal.

The terrain is small stands of gambel oak in grassy meadows with occasional sage brush. We're looking south. Down near Mapleton, a foothill fire is smoking up the valley.

The trail's riding platform is broad and smooth, with no significant bang-over rocks. Turns are highly banked for speed. While most riders will love descending this trail, it's also an easy climb. I passed a couple of uphill-bound warriors in full battle armor riding DH bikes, and they weren't working too hard.

Little Rocky rests on the berm of a turn. Nice thinking, trailbuilders, placing the rocks so dipwads don't cut across the turn.

The trail will cross over to the east side of Mercer Hollow, then back to the west side. At mile 1.1, the singletrack ends on a narrow cindered road. At this spot, you can turn right (uphill) to head for the paved neighborhood street, or go across to the doubletrack to resume descending.

The doubletrack is 0.9 miles long, dropping another 200 feet. It will hit Suncrest Drive at a chain-link fence gate (with a couple of heavy-construction tires alongside in 2016).

Heading northeast toward the far side of Mercer Hollow, with Lone Peak on the skyline. The rock appears to be partially-mineralized limestone (affected by the igneous intrusion that brought gold and silver deposits as it built the granite of Lone Peak).

For the south-side loop ride:

For the loop ride using South Maple Hollow and Eagle Crest, turn uphill and crank west up Suncrest Drive in the bike lane. At the first side-street on the left, cross over to Brooklings Drive.

Follow Brooklings to the first street on the right. Jog right-left to Brookside Drive and continue uphill to the end of the road to catch the new singletrack on the left. At the trail fork about 1/2 mile uphill, keep to the right and uphill to continue climbing. (The left fork takes you down to the flood-control dam. Cross it and go around the pond if you want to take the OLD singletrack uphill.)

Descending the eastern side of Mercer Hollow.

If you're taking the doubletrack uphill, stay on Brooklings until you hit a T intersection, then jog right-left to continue west to the end of Chimney Stone Road. Crank 1/2 mile up the doubletrack from the pavement circle at road's end. This doubletrack has some loose cinder, and I hate gravel/cindered roads, but it's not awful. As you reach the dam, fork right for the new Maple Hollow South, or go around the pond for the old trail. See the South Maple Hollow page for route-finding information on your way uphill to the Maple Hollow trailhead.

On the doubletrack southbound.

Bottom Line:
This is a superb trail, well-built and fun to ride. Great as a downhill or out-and-back all by itself, but also good for extended rides using nearby trails. I recommend the clockwise direction for the loop ride below, as Mercer Hollow is oodles more fun as a DH than Maple Hollow South.

Getting there: From I-15 in Salt Lake City, take the Bluffdale exit and head east on Highland Drive toward the mountains. As you reach the traffic light at the top of the hill, about 3/4 mile after leaving the freeway, turn right on Traverse Ridge Road. Drive about two miles up to the top of the mountain to the stop sign.
From Utah County, get on the Timpanogos Highway. At the Lehi-Highland border, go north on Highland Blvd at the big stop light east of Smiths. This will become Suncrest Drive as it enters Draper. Climb to the stop sign at the top of the hill.
Deer Ridge (Maple Hollow) trailhead:  At the stop sign in Suncrest, get on Deer Ridge Drive (right turn from SLC, straight from Utah Co). Go 0.9 miles. Just before the road crosses a bridge, turn right onto Elk Glen Drive and immediately turn left to park at the small picnic area.

Eagle Crest trailhead:  From the hill-top stop sign above, go south on Traverse Ridge Road (straight from SLC, left turn from Utah Co). To to the end of the road and park.
Top of Mercer Hollow: 
There is some roadside parking off Suncrest Drive near the top of the trail, on the east side of the road 1/2 mile downhill from the four-way stop in Suncrest. But there are some cautions. In 2016 this is an active construction area, so be sure you're not in an access-point or work zone!
Bottom of Mercer Hollow:  There's room for 3 or 4 cars at the bottom of the doubletrack portion of Mercer Hollow on Suncrest Drive.
Brookside Drive:  Brookside Drive turns to the west off Suncrest Drive, just uphill from the Maple Hollow subdivision. Drive past the homes and uphill to the end of the road. The South Maple Hollow trail is on the west side of the road. It will take you uphill, where you can connect to the Eagle Crest trail (or cross over the ridge to Ann's Connector).
