Robs Trail

Robs Trail is an important entry point to northern Park City riding. It's a beautiful and popular trail that sees plenty of riders. While only 2.6 miles long with 800 feet of climbing, it's the starting point for many loop rides via connections to Ambush, Hunter, and Mid Mountain -- and via Mid Mountain to Crest Connector, Holly's and trails of The Canyons Resort. Note that the portion of Robs between the Rosebud and Ambush trails is one-way uphill-only for bikes.

Some popular riding options from Robs trailhead are:
Robs to Mid Mountain out-and-back: 5.2 miles, 800 vertical.
Robs up, Ambush down, Rosebud back: 6.3 miles, 1200 vertical.
Robs up, Hollys down, Rosebud return: 12 miles,1600 vertical.
Robs-Hollys, pavement, Collins up: 13.8 miles, 2200 vertical.

Just getting started. We're about a half mile  up Robs Trail, looking northeast over Bear Hollow.

The featured ride below is the big loop that includes a mile of pavement. (If you hate pavement, take Rosebud back from The Canyons' base.) I include track files for all three loop rides above.

Starting at Robs trailhead puts 600 vertical into two miles of climbing right at the end. I like one last grunt to finish off a ride, but many don't. So if you want to finish on a downhill, start at The Canyons and put the pavement first.

 View uphill on Robs as we near the fork with the return singletrack.

From Robs trailhead, climb a couple of switchbacks, then pass Collin's Trail, which is the return route for the big loop. About 1/3 mile later, turn right to continue on Robs westbound. (To the left is Rosebud's Heaven, your return route for the not-touching-pavement loops.) From this point to the Ambush trail fork, Robs is now one-way uphill for bikes.

At mile 2, the forest will open up on a ridge, with views to the south as you head west. At 2.2, you'll reach the junction with Ambush. (For the shortest loop, fork left here.) To continue on to Mid Mountain and Holly's, keep left and climb uphill.

View to the south as we approach the junction with the Ambush Trail.

For the shorter Ambush loop option, turn left. Keep left at the next trail fork as the trail joins Holly's. Not too far down the trail, make a hard left to take lower Ambush to Rosebuds. Cross the doubletrack and head east along the south-facing slope. Fork left (uphill) when you hit Rosebud's. Go over the hill back to Robs.

On to Holly's. From the Ambush junction, it's about 1/2 mile to the Mid Mountain Trail. Fork left. (The Hunter Trail, on your right, can be ridden as an out-and-back. The trail goes to Pinebrook, but there's no public easement, so don't use this as a return from Mid Mountain unless you're riding with a Pinebrook resident.)

View through the fall colors between the Ambush junction and the Midmountain Trail.

The Mid Mountain Trail will give you a couple of switchbacks worth of climbing at first. After a short traverse in gambel oak and maple, you'll be in deep fir and aspen forest, breaking out onto an occasional ski slope.

At mile 3.7 of your ride, pass the Crest Connector. If you want, it's 1.3 miles (and 450 vertical) from here to the junction at upper Mill Creek.

We'll be climbing through the dense fir forest in mid-right of this photo.

The Mid Mountain Trail is pretty smooth here. The climbing is sustained, but not hard. You'll spend three miles and gain 500 feet on the Mid Mountain.

Typical view on the Midmountain Trail.

At mile 4.4, the Mid Mountain trail breaks onto a gravel road on a ridgeline. Instead of crossing, go left -- eastbound -- on the gravel road. After 100 yards, go left on a broad bench-cut that turns into singletrack. This is Holly's Trail.

It you want to add some miles, you can keep going south on Mid Mountain, then return later. It will be mildly uphill coming back. Red Pine Lodge is about a mile south.

A short distance down Holly's, you'll hit the alternate downhill (one-way) trails. If you're up for some more-technical riding, take Double Down, Insurgent, or Ricochet. My mileage assumes you continued down Holly's.

Early on Holly's Trail.

As Holly's drops off the ski slope to a doubletrack nears The Canyons' base, find your return route:  (1) downhill right, to pavement to Collins for the bigger loop, or (2) uphill left if you're returning via Rosebud. 

For the ST loop option, go left uphill on the broad trail about 1/3 mile. Find Rosebud's Heaven on your right (northbound). Climb Rosebud across the hill to Robs, then descend.

View on Holly's as the afternoon shadows deepen.

For the big loop, take the paved path past the gondola and then between the buildings. Coast out to a road and turn left, then left again at the bigger road. Coast east and downhill on Summit Drive to the traffic circle. Take Cooper Lane, then Sunpeak Drive. (Consider a cell with a Google map, or my GPS track.)

Find the Sunpeak (Collins) trail on the left about 50 yards before the end of Sunpeak Drive. (2010: no trailhead parking, not even a sign!) Alternate: The DuBois trail starts at the north end of the parking for the recreation center on Bear Hollow Drive 1/3 mile away. For either trail, just keep heading uphill. When you hit Robs, head R downhill 0.6 miles to parking.

View through the Aspens as we climb Collins back toward Robs Trail.

Getting there, Robs trailhead:  Take I-80 eastbound out of Salt Lake City and cross Parley's Summit. Take the Park City exit and turn right. For Robs Trailhead, drive 2 miles on 224 toward Park City. Turn right on Bear Hollow Drive. Head uphill 1.2 miles. The trailhead parking is on the left, just before a hairpin turn in the road.

Bathroom:  At The Canyons. None at Robs trailhead.
Water: The Canyons, plus convenience stores 1/2 mile away from trailheads.
Camping: None in immediate area. Nearby at Rockport, Echo, or Jordanelle Reservoirs.
Bike Services: Multiple shops in Park City.

Canyons trailhead:  Exit I-80 onto 224 as above. Pass Bear Hollow drive, then turn R into The Canyons at mile 2.8 from the freeway. Follow the main resort drive uphill. Go straight at the roundabout. As the road splits in front of the big hotel, veer left (south). Now turn R uphill just past the big buildings. Look for a gravel parking area on your right, just before the road turns north again. Park here. Exit the far end of the parking lot to a paved path that goes north between commercial buildings. Keep going until you pass the gondola. Ignore the smaller trails crossing the lawn (those are downhill routes). Drop slightly to the left onto a broad path in the canyon bottom and begin going uphill to reach Holly's and Rosebud's Heaven.
