Mountain Trails Foundation

Mountain Trails Foundation Building, maintaining and protecting non-motorized trails in Park City, Utah since 1992. A member-supported nonprofit organization.

BUILD, MAINTAIN, PROTECT
Mountain Trails Foundation is a member-supported, non-profit organization dedicated to building, maintaining and protecting trails for non-motorized recreation in the Park City area. Creating and maintaining a seamless, year-round trail system is a monumental undertaking. Mountain Trails works closely with Park City Municipal (the City), Snyderville Basin Special Recreatio

n District (Basin Rec), Deer Valley and Park City Resort, local land trusts and private land owners. FUNDING TRAILS
Funding for both winter and summer operations comes, in large part, from membership, donations, corporate support, grants and revenue from our 4 trail races: Round Valley Rambler, Jupiter Peak Steeplechase, Mid Mountain Marathon and Tour des Suds. ADVOCACY
Trail advocacy is part and parcel to protecting access to trails. Mountain Trails helps keep trail users up to speed on etiquette and safety issues by providing on-trail signage, messaging in social media, and a monthly newsletter. By keeping trail users in the know, we help mitigate conflict between user groups and make the trail system a safer, happier place to play.

🤘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!
