On December 28, 2025, a Basin Recreation groomer made its first pass of the season on the fields at Ecker Hill. The crew's own trail log described the result as "only about an inch of compaction over the grass" and warned skiers about spotty ground. The Woods got groomed the next day. The Basin 5k and the Green Heart 5k, the two loops built only for Nordic skiing, were still too thin for equipment almost two weeks later.
That gap is how winter works here. In the Snyderville Basin a storm doesn't reopen everything at once. The trails come back in an order, and the order is predictable once you know what the district plows first and which routes need deeper snow.
The Plow Goes Out Before the Groomer
Basin Recreation's trails FAQ, updated in October 2026, is plain about this. After a storm, crews clear snow from every commuter pathway and trailhead before they groom any trail, so the district keeps no set grooming schedule. The asphalt path you use to walk to Kimball Junction or Bear Hollow will be clear well before a groomer reaches a Nordic loop.
The district posts grooming as it happens on its interactive Winter Map. The map also shows whether classic tracks were set, plus the status of Willow Creek Pond and the turf at Matt Knoop Memorial Park. Classic tracks come last of all. Setting them takes more snow than a regular groom, so the FAQ says they may not appear early in the season.
Last Winter, in the Order It Happened
The 2025–26 season was thin, and that makes it a clear record of the sequence. Basin's Winter 2026 Trail Updates log tracked it week by week:
| Date | What the crew groomed or reported | What was still too thin |
|---|---|---|
| Dec. 28–29, 2025 | Ecker Hill groomed, then The Woods | Singletrack was usable only early in the day, while frozen |
| Jan. 2, 2026 | Rain undid the early base; the crew advised staying off Basin trails for a few days | Trails saturated and prone to damage; asphalt commuter paths suggested instead |
| Jan. 9, 2026 | All branches of Willow Creek, Ecker Hill and The Woods | Ancient Forest at Silver Creek Village, Crooked Mile, Green Heart, Basin 5k |
| Jan. 16, 2026 | Surface scratch on Willow Creek, Matt Knoop and McLeod Creek; light groom on the Ecker Hill fields | Grooming paused after that day |
"It ain't much but it's something."
The crew opened its December 29 update with that line, written after the first Ecker Hill groom. By January 16 the same log called Ecker Hill "your best option for Nordic," and by then it was close to the only option.
Why the Nordic-Only Loops Wait Longest
Basin's Winter in the Basin guide lists 45 kilometers of groomed trail. Ten kilometers are Nordic-only and the other 35 are multi-use. That guide was published in February 2025, so it is the district's most recent full route list rather than a promise for 2026–27.
The two Nordic-only loops are the Basin 5k, which starts from the Overland and RTS trailheads, and the Green Heart 5k at Willow Creek Park. Both are groomed for skate and classic skiing when conditions permit. Dogs, bikes, hiking and snowshoes are not allowed on them. Last January both were on the too-thin list while the multi-use routes around them were already groomed.
The multi-use routes are the ones that come back early. They include the Ecker Hill Loop, Woody's Lane and Parley's Lane in The Woods, the Willow Creek Loop, McLeod Creek, Miss Billy's, Crooked Mile in North Round Valley, the Ancient Forest Loop at Silver Creek Village, and the Millennium Trail from Newpark to Bear Hollow. Leashed dogs, fat bikes, walkers and skiers can all use them. Basin also packs a few steeper, narrower routes for winter use as conditions allow. Those include Up Track and Pale Green Dot from the Discovery Ridge Trailhead, plus Saved by the Bell and the Trailside Loop near Trailside Park.
So early in the season, a dog walker in Jeremy Ranch or Pinebrook may have more groomed trail than a skate skier does. The skier's best early bet is the Ecker Hill fields. The Nordic-only loops come later.
One local caveat applies this year. Basin is rebuilding the Trailside Wheels Park in the same park and lists construction as a project phase. Basin's project FAQ says nearby amenities should stay open apart from intermittent work-zone closures, that parking may be limited, and that Trailside East Park has extra parking. If you head to the Trailside packed loops this winter, watch for posted work zones. Our summer post on Trailside's rebuild covers how the project got here.
Run-A-Muk and the Pond Run on Their Own Triggers
Two of the Basin's most-used winter spots don't follow the grooming order at all.
Run-A-Muk. The off-leash area sits below Utah Olympic Park and covers 43 acres with 2.8 miles of hiking-only trail. Basin's Run-A-Muk rules page requires dogs to stay in sight and respond to voice commands, and owners must carry a leash and use it within 150 feet of a public trailhead. It goes into this winter freshly resurfaced. TownLift reported that it reopened September 24 after repair work on earlier weather damage. Volunteer cleanups were set for October 8, 16 and 30 to get it ready for snow.
Mud decides Run-A-Muk's hours, not snow. Last winter Basin closed it daily at 11 a.m. starting January 26 to protect soft trails. KPCW reported that it reopened dawn to dusk on February 18 after winter weather arrived. The midday closures were back by late February. After the separate annual spring closure, the area reopened April 20. The 11 a.m. cutoff was a response to conditions, not a standing rule. A freeze-thaw week in December could bring it back.
Willow Creek Pond. The pond becomes a free natural rink only when the ice allows. Crews clear the snow and mop the surface, skaters bring their own skates, and dogs are not allowed on the ice. Opening dates have varied widely. In the 2024–25 season the pond opened December 11 and closed January 1. Basin explained then that wet snow can insulate the ice and melt it. Last season crews started clearing on January 1, found weak spots and holes, and didn't open the pond until January 21, 2026, according to TownLift. Skating season depends on cold, not on how much snow has fallen.
Where the Groomers Belong to Someone Else
Round Valley is not on Basin Recreation's grooming route. Mountain Trails Foundation maintains its winter system and describes about 25 kilometers of Nordic trail groomed daily or as conditions warrant. In a November 2025 TownLift piece, executive director Lora Anthony explained the fall prep that comes before that grooming. Crews mow the corridors that become Nordic track, install winter wayfinding and set snow fencing and stakes to guide groomers in the dark or in storms.
Last winter showed why it helps to have two crews and more than one elevation. When rain wiped out the Basin's early base in January, Basin's own log sent skiers to Bonanza Flat, where Mountain Trails Foundation was "keeping the Nordic game alive." TownLift later reported that Bonanza Flat became Park City's most reliable cross-country option. KPCW reported that White Pine Touring had 38 skiing days, compared with 130 in a normal winter. Nordic center director Richard Hodges described the season to The Park Record this way: "Everybody ended up chasing snow all over the place."
Your First Week of Real Snow
Put together, these sources give a practical order for the first storm that sticks:
- Check the Winter Map before you load the car. It shows grooming, classic track, pond and Matt Knoop turf status in one place.
- Expect Ecker Hill and The Woods first, then the Willow Creek branches. That was the order last season.
- Use singletrack early, while it's frozen. Basin's crew repeated this through last winter, as trails turned to mud by mid-morning.
- Look at the trailhead cameras before driving to Summit Park. Basin calls winter parking at Parkview and Short Stack "extremely limited" because of snow removal.
- Leash your dog and give the groomer room if you meet one on a multi-use trail, as the district asks.
- Leave the Basin 5k and Green Heart 5k to skiers. Dogs, bikes, hiking and snowshoes are not allowed on either loop.
Last year's trail update log began on December 29, after the first Ecker Hill groom.
Knowing which Basin trails open first is also useful when you're choosing a place to live here. Last winter, homes near Willow Creek Park, Ecker Hill and The Woods were close to the first groomed trail in the district.
