Yellow Fork

Yellow Fork is a surprisingly nice trail in the Oquirrh Mountain foothills at Rose Canyon. Among the many options are two main choices: there's a nice 7-mile singletrack loop ride with 1300 vertical feet of climbing, and there's a smooth 2-mile doubletrack ride in Yellow Fork Park that goes to a lovely picnic area. Choose your ride based on the abilities of your riding companions.

The singletrack ride is mostly intermediate technical, easier at the lower altitudes, with a smattering of advanced tech at the top. The climbing is easy, except for the last mile before the summit, which involves 700 vertical but is very rideable for those with good legs and lungs.

Much of the trail is on a north slope, so it stays snowy and through early spring. The trail's riding season is late April through early November

At the top of the singletrack you break out onto a windswept ridge, where you'll have this view of the copper mine tailings to the north. May 10, 2002.


You'll spend much of your time riding alongside small creeks in "riparian" habitat. I've seen deer, wild turkey, rabbits, and squirrel every time I've been on this trail. Overhead, maples and oaks (and a few quakies near the top) provide shade. Dwarf waterleaf, yellow fawn lily, and grasses grow under the trees. It's a surprisingly pretty ride.

Yellow Fork is a popular horse-riding area. Even weekdays, there are usually a few horse trailers in the parking area. Please be courteous when approaching riders on the trail.

The loop can be ridden either direction. I prefer clockwise. It's also easier to navigate that way -- fewer trail choice decisions. But come prepared with a map, trail description, and odometer. If you're the type that is easily lost, take the GPS too.

Trail note 7/06:  We've been informed that the property owner wishes to assert control over access to the area at the bottom of the doubletrack (referred to as "fire road") at the west end of the Yellow Fork Loop (see map). As with many foothill-area trails, the Yellow Fork Loop trail crosses private property. Although the trails are long-established routes, we ride them only at the pleasure of the land owners. Please respect any posted signs.
     When riding the north-end singletrack (as described in the counter-clockwise loop), consider an out-and-back option with a turn-around at mile 2.9. For the clockwise loop, you can complete a loop without entering this area by turning right downhill on the small ridgeline singletrack at mile 3.2 (from "view" to a left turn at "ridge"), then right downhill to the picnic area.
As always, if you have important new information regarding any trail, please post it to the "Trail Conditions" section of the UtahMountainBiking forum.

The Family Ride:

From the parking area, go right (west) up the cindered road. Just continue straight, as the singletrack branches and crosses over. At mile 0.5, you'll see a few picnic tables on the left. This is where the loop ride forks. Continue on to mile 1.9. The doubletrack ends here among multiple picnic tables, in a shady glen along the creek. From here, the bigger kids can try their hand at a bit of the singletrack, while the little ones play in the creek.

Yellow fawn lily blooms in the spring along the damper parts of the trail. This pretty flower is also called trout lily and glacier lily.

Getting there: From I-15, take the Bangerter Highway and head west. After the highway curves north, turn left on 126th south (traffic light and big pedestrian overpass) at mile 6.0. 126th becomes 131st. In Herriman, turn left on Rose Canyon Road. Set odometer. 0.9 mile later, turn right at stop sign, then keep left at 2.3 to continue on Rose Canyon Road. At mile 4.4, pavement ends at the creek. Find a parking spot. The trail begins right along the creek, going uphill. GPS N 40 27.917' W 112 05.075'
