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.
Good Morning all! Here is your Sunday March 15th trail report.
A nice chilly morning in Bonanza kept things nice and firm for the nordic trails. But make sure to get out there early before things turn soft.
Round Valley is looking mostly dry throughout with some muddy and wet spot on the single track.
We have a machine out on Big Easy in the inner valley cleaning up some turns so heads up and pass kindly.

Good Saturday Park City!
Here is the daily grooming report for Mar. 14th 2026.
Round valley is drying up quick. Much of the wide track is fully dry and there are only a few areas tucked into the oaks on the single track that are holding on to some mud.
Bonanza got a fresh groom this morning, though we didn’t get a full freeze last night. Classic lanes have been set where possible. The snow is super sugary. The single track was looking in decent shape with few visible post hole areas which was mostly due to the foliage under and around the packed track. This morning it is solid but could soften quickly with the warmer temps later this afternoon.

Good morning folks!
Friday the 13th's grooming updating coming at ya:
Warm tempts this morning both down low and up high, Quinns and Empire Pass around 38 degrees early this morning. Empire Pass has been a bit windy, and a bit breezy down in Bonanza Flats at times. Despite the warm temps, the snow was still a bit frozen in Bonanza, which led to the single track feeling nice and firm early this morning and allowed Roy Boi to lay down some nice cord on the Nordic track as well. Today is supposed to get quite warm, and snow conditions can change very quickly when the sun is out like it is this morning. Get out early and be mindful of your impact on the single track as conditions inevitably change throughout the day.
Round Valley is still in the drying process, still best to get out early down low as well, as muddy spots throughout the single track system still exist. Next week's temps are looking crazy though! Should massively help dry things out. Time to get that bike summer ready if you haven't done so already!
Whatever you get into today, we hope you have a great day!

Happy March 11th! Here is your daily trail report..
Not much new to report. We're stuck in high pressure with nothing but sunshine and warmer temps.
The double track in Round Valley is pretty much completely dry while the single track is still holding mud and moisture in zones.
The snow is doing its best to hold on up in Bonanza Flat. The nordic was groomed this morning with classic lanes set. The single track was groomed a couple days ago and is staying firm.
The earlier the better. Things soften up in the afternoon so be mindful if you're leaving post holes and ruts.
