Shadow Lake Loop
Park City Mountain Resort

The Park City area has excellent high-altitude alpine biking. The snow clears about mid-June to early July. The trails on the west side of town are shaded and cool, and clear of snow relatively late compared to the east-side trails. This page describes an old classic ride, Shadow Lake, which offers a lot of different (and confusing) riding options.

On August 10, 1998, Dehn, Rob, and Mike arrive at Shadow Lake with Jasmine, Mike's energetic Jack Russell terrier.

You can ride the loop either direction: it depends on whether you want to hit John's audacious quakie ride uphill or down. Or if you hate John's, there are ways to climb (and descend) via straight smooth trail.

Fair warning: every time I do this ride with locals, they take a different route. I'm supplying six different "official" versions of this ride (see the GPX course files)..

A humid August morning in 1998 after a light rain. Four ER docs and two techs climb up Sweeney's and struggle over the muddy slippery roots of John's Trail. We take a break, and somebody snaps a photo of Bruce's helmet hair, wife-beater shirt, and not-racing-shape body.

The shortest route (via Spiro) will be about 12 miles. The easier CMG route is 15.

You'll gain 1500 feet of elevation, starting at 6900 from PCMR parking.

The Silver King mine at the top of Johns. This photo was in my pile of old 1998 pictures, but it doesn't look like it was taken the same day.

Take a current Park City trail map. They're free (a donation is suggested) at Park City bike shops. The multiple interconnecting trails can be a bit confusing. New trails appear every year. The upper Sweeney's to lower John's area is a jumbled mess of cheater routes and interconnections.

No problem -- just ride. Ask for directions. And if you're totally lost, aim your bike downhill and keep pedaling until you find pavement.

We haven't even made it up Steps yet, and it's time for another break. 

My original ride (back in the previous century) was up Sweeney's, then John's, then Steps, then Thaynes Road to the lake. The return was by Keystone to Meadow Road to Steps to Johns again, then off on 4:20 (which had another name back then) to Gravedigger to Daly Canyon.

There are dozens of permutations on this ride. I'm not going to spend a lot of wordage describing specific routes. The CMG/Apex route will be our featured ride (see mileage chart below). 

View from Steps down toward the ski lifts near the top of John's Trail. 

Easiest climbing route: Crescent Mine Grade, then Thaynes to Apex, Keystone.

Easy but BORING: King Road to Thaynes Road

Hardest climbing routes (tie): Sweeney's then Johns, Steps, Thaynes. Or Spiro to Powerline, Thaynes

Most-fun descending route: Keystone to Apex, Thaynes to Steps, Johns, 4:20, Gravedigger, Ontario Ridge

Dehn looks over the valley above Park City on Thaynes Road. August 10, 1998.

Getting there: Crescent Mine Grade. On Park City's main drag, turn towards Park City Mountain Resort (PCMR). Turn right on Empire then veer right again at Silver King Drive. Pull into the big parking lot. Pedal southwest across the parking lot, toward the Payday lift and the Alpine Slide. Find the gravel road on the edge of the parking lot, heading southwest between the First Time ski slope and the buildings.Continue uphill.

Mike, an emergency physician living in Park City, cranks past the ruins of the Jupiter mine. August 10, 1998.

Getting there: Spiro Trail.  On Park City's main drag, turn towards Park City Mountain Resort (PCMR). Turn right on Empire then veer right again at Silver King Drive. Pull into the big parking lot. Start pedaling. Go north out of the parking lot onto Silver King Drive and turn left toward the mountains. Turn right onto Three Kings. The next left will be Crescent Drive. Pedal about 1/4 mile uphill on Crescent. The trail is the singletrack at a blocked-off paved area on your right where Crescent Drive turns left. N 40 39.390' W 111 30.895'

Getting there: Sweeney Switchbacks. On Park City's main drag, turn towards Park City Mountain Resort. Turn right on Empire then veer right again at Silver King Drive. Turn left on Lowell, then pull right into the parking area. Park. Pedal back out of the parking lot onto Lowell and turn right, uphill. Keep straight past the resort. When you reach the spot where the road turns around in a loop, the doubletrack straight ahead is the trail. (Do NOT park in the neighborhood!) N 40 38.785' W 111 30.076'
