The 8 best mountain bike rides in Park City.

Round Valley is the network everybody rides in June while the good stuff is still under snow. It sits low, on rolling open ground near Quinn's Junction on the east side of town, and it dries out weeks before anything up high.

The trails are flowing and mostly gentle, with enough interconnection that you can build a ride of almost any length out of them. It is where beginners get their confidence and where everybody else does an easy recovery lap, which means it is busier than its difficulty suggests.

There is almost no shade and very little water. It is a morning ride in July, not a midday one.

Glenwild is the first ride on this list that feels like real Park City singletrack. An eight-mile loop out in the basin north of town, built with long, well-cut switchbacks that work whether you are grinding up them or letting go down them, and technically easier than the elevation profile suggests.

It is the ride to do when you want a proper hour and a half without committing to a mountain. The climbing is steady rather than punishing, and the descent is the kind of sustained flowing singletrack that people move here for.

It also connects outward into the wider basin network, so it scales up if you are feeling better than you expected.

This is the classic. Climb Armstrong or the Crescent Mine Grade up from the Park City side, traverse a stretch of the Mid-Mountain Trail, and descend Spiro back to where you started. Roughly nine miles with about 1,800 feet of elevation change, and it is the loop locals name when a visitor asks for one ride.

Armstrong is uphill only for bikes, which removes the usual anxiety of a climb on a shared trail. It rises through aspen groves and past mining relics from the silver era, then into pine shade and out onto open ski-run meadows, which is a lot of landscape change for one ascent.

Spiro on the way down is fast without being frightening. If you only have time for one ride in Park City and you can handle a sustained climb, do this one.

The trail that earned this town its reputation. Designated an IMBA Epic, the Mid-Mountain runs roughly 20 miles from the Deer Valley side across to the Summit Park neighborhood, holding close to 8,000 feet the entire way instead of climbing and dropping.

That contouring is the whole character of it. The difficulty is duration and altitude rather than gradient, and the reward is twenty miles of pristine singletrack through aspen and pine with the valley opening and closing beside you. Almost every other trail on the mountain touches it somewhere, so you can join and leave it at a dozen points.

Doing the whole thing end to end is a serious day and needs a shuttle or a very long return. Most people ride pieces of it, which is the sensible way to treat a trail this long.

Deer Valley runs one of the longest-established lift-served bike operations in the country, opening for summer around the middle of June and using the Silver Lake Express and Homestake Express chairlifts to put riders on the mountain without the climb.

The reason to pay for a lift here is not laziness. It changes what you can ride in a day: you get descent after descent without spending the morning earning the first one, which is how downhill skills actually develop.

The resort has been building out new trails alongside its larger terrain expansion, so what is open changes year to year. Check current status before you drive up.

Woodward Park City sits out at the north end and runs a lift, called Hot Laps, specifically for its bike park, opening in the second half of June. It is built around progression rather than mileage, with features sized so you can move up gradually rather than committing to something you cannot ride.

Park City Mountain also runs lift-served riding in summer, which means there are several genuinely different paid options in one town alongside 400 free miles.

If you are learning to ride features rather than distance, a day here is worth more than a week of exploring trails you are not ready for.

The Crest is the ride people plan trips around. From high on Guardsman Road it follows the ridgeline that separates the Wasatch Back from the Salt Lake side, and the classic version is a shuttled point-to-point of roughly 13 miles out to the Big Water trailhead in Millcreek Canyon, with a longer variation that runs back out toward Park City instead.

It sits high enough that the season is genuinely short, roughly July through September, and it is exposed enough that an afternoon thunderstorm up there is a serious situation rather than an inconvenience. Start early.

There is also an access rule to sort out. Millcreek Canyon lets bikes descend that side only on even-numbered calendar days, and its canyon road closes for construction from time to time, so check current access and confirm your shuttle before you plan the day around it.
