Winter Trails Overview
80KM OF GROOMED WINTER TRAIL
While Park City has long been known as an alpine skiing destination, Summit County’s Nordic Trail System has blossomed to nearly 80 kilometers of superbly groomed trail. As fat-tire bikes, snowshoeing and winter trail running grow in popularity, the winter single-track trails are expanding likewise.

Follow our social media pages for the latest news and trail updates. We try to report weekly in the summer and daily in the winter.
*Trail Impact Alert* Mountain area (Marsac to Armstrong) trails are closed for fire suppression operations. This includes everything accessed from the first-time trailhead, Armstrong, and Mid Mountain. Even trails not directly adjacent to the fire will be impacted by crews accessing the site. Please stay off these trails so crews can extinguish this fire ASAP.#BREAKING: According to Utah Fire Info, the Thaynes Canyon Fire was 0.5 acres in size as of 7 a.m. on the eastern aspect of Pinecone Ridge. It was uphill and west of the lower terminal of the Motherlode Express lift.
Briley said crews were responding to the scene at 7 a.m. Park City Fire District had dispatched two fire trucks and a side-by-side, each staffed with three firefighters.
Summit County alerted residents not to report the lightning-caused fire around 7:30 a.m. since the fire district was already responding.
"At this time, there's no danger to structures or the community," the Park City and Summit County governments wrote in a social media post.

🤘More brown pow in the forecast! ☔️
‼️Please remember, if the trail is too wet, please turn back, find an alternative and/ or wait to get out on them‼️
🎸Maintenance on Cyn City is finished, and she is ready to rock, roll and rip!
🤿Phase two of Silver Queen to Loose Moose is moving along swimmingly.
🍑 The crew busted their peaches and hand dug about a half mile of new tread on 9K to Mid Mountain.
🏹Back slope was carved, vegetation was trimmed, and tread was raked on the currently known as Huntsman hiking trail. The grand opening is coming soon.
🦦The Weber River trail system’s corridor was also cut back.
🏃♀️Saturday is the Mid Mountain 50K, so expect extra traffic.
Sunday is our Volunteer Dig Day from 9 a.m. to Noon. Come help the crew continue to hand cut in the new hiking trail from 9K to Mid Mountain.
PCMC Fuel Reduction crews have Iron Mountain Hiking trail closed through Saturday and will shift over to Thaynes Canyon starting Monday, which will lead to closures on Armstrong.
Have a wonderful weekend everyone!
MTF Crew
