Things to know before you go

Bells on trails keep everyone safe. Use and listen for them while you are on the trails. Pick up a freebie at a local shop or pick up a membership gift from Mountain Trails.

Consider using the marked winter singletrack when biking, snowshoeing or hiking. Winter singletrack is a lot more fun and using it will help preserve the groomed trails for other users.

Dark spots accelerate melting. Help reduce melting by removing debris from trails and avoid tracking mud onto the snow.

Please do not ride (fat bikes and mountain bikes) if you are leaving a rut. If snow or dirt is too wet or soft to ride a straight line, then turn around. Tires can leave ruts that ruin groomed trails for other users. Ruts lead to erosion and costly trail repairs.

If you are breaking through the trail surface leaving a rut, losing traction and are unable to ride in a straight line, please reduce your air pressure.

2-5 PSI is a good range for SOFT GROOMED SURACE AND BASE.

4-8 PSI is a good range for HARD-PACKED SURFACE AND BASE.

Where to Fat Bike

Round Valley

by

Park City’s crown jewel of open space, Round Valley, comprises 2,100 acres of rolling terrain. Free to the public and open for multi-use, Round Valley offers the most extensive groomed Nordic and single-track trails throughout the winter. With options for all abilities and select areas dedicated to Nordic only, there’s something for everyone. The 6-mile-long Big Easy Loop is groomed for fat bikes, as are the directional PorcUclimb Down Dog trails.

Well-behaved, off-leash dogs are welcomed (although not permitted in Nordic-only areas). Classic tracks are set as conditions allow. The grooming report and interactive map are updated daily throughout the winter.

Willow Creek

by

The Willow Creek system of trails connects Park City to Kimball Junction with over 15k kilometers of groomed trails. The area includes Nordic-only ski options in the Green Heart 5k (the largest working farm in the area) as well as dog and beginner-friendly trails throughout Willow Creek Park.

The 66 acres of undeveloped open space that adjoins the popular Willow Creek Park is a splendid example of the native wet meadows and high mountain grasslands that once dominated the landscape in this area. This undeveloped area provides a sense of scenery and balance among neighboring homes. The property is under a conservation easement held by Utah Open Lands.
