Wyoming Snowmobile Trails: Map, Dates, Permits

Q: What permit do I need to ride a snowmobile in Wyoming?

Wyoming follows the the permit is the registration model. The snowmobile user decal is the instrument checked on the trail. Wyoming State Parks publishes the current price on its permits and fees page. Wyoming State Parks, State Trails Program publishes the current amounts and is linked on this page.

Q: Where does the Wyoming trail map on this page come from?

From U.S. Forest Service, loaded live in your browser each time the page opens. 555 trail lines were counted in it when this page was built. The published lines cover the whole state. A federal publisher, and the only one in this vertical. Federal government works are generally not subject to domestic copyright, which is a materially stronger position than any state source here.

Q: How do I find out whether a Wyoming trail has been groomed?

Grooming reports come from the club or county that runs the groomer, usually through Wyoming State Parks grooming reports or the local club's own page or social media. Michigan is the one state that publishes a per segment open or closed status; everywhere else the club report is the source, and one Idaho county publishes per segment grooming dates.

Q: Can I navigate from the map on this page?

Use it to see where the Wyoming system runs and which county you are in. The lines are drawn at a precision chosen to keep the page fast rather than to place a trail on the ground this week. For riding, carry the club or agency trail map: reroutes, closures, unbridged crossings and changes in landowner permission are not in the mapped lines.

Trail maps, season dates and permit rules, sourced to each state agency. Current trail conditions are published by the club, county or state authority that maintains each system, and every state page links that authority.

Conditions

Wyoming trail conditions

Current Wyoming trail conditions are published by Wyoming State Parks grooming reports. Trails close for a bridge out, a landowner withdrawing permission, a timber sale, thin base or open water, and those decisions are made locally by the club, county or district that maintains each trail, often day to day.

A yellow tracked grooming tractor parked in falling snow with a wide steel drag hitched behind it and a second drag stacked at the edge of the clearing — The machine that makes the difference between a trail and a field. The tractor packs, and the steel drag behind it cuts the moguls down and lays a flat surface that then sets hard overnight. Grooming is why trail systems have opening dates at all: the base has to be deep enough to carry this before anybody can run it. “Grooming unit and drag” — Magnum x, via English Wikipedia — Public domain

Season

Wyoming snowmobile season dates

No statewide dates

Wyoming publishes a typical window of mid December through April 1 and labels it typical rather than fixed, so there is no statutory date to quote. The reason is structural: the State Trails Program says federal land hosts 98 percent of Wyoming trails, and federal land opens on snow and on the managing forest, not on a state calendar.

Season dates are the legal window. Whether a trail is groomed or rideable on a given day depends on snow and on the club or county that maintains it.

Permits

One instrument does both jobs, and it is what gets checked on the trail. Visitors are generally not exempt from it.

Current Wyoming fees are set by Wyoming State Parks, State Trails Program.

Three snowmobiles parked in fog beside a metal hut and a solar array on a rime covered summit, surrounded by stunted spruce buried in snow — The top of a trail on a bad visibility day, with the machines parked at a summit hut. Trail systems climb, and the weather at the top of one is routinely a different weather from the weather at the bottom, which is why riders check the summit forecast as well as the trailhead. “Rangeley Lakes Scenic Byway, Trails End Atop a Snow-capped Mountain” — U.S. Department of Transportation, National Scenic Byways collection, held by the National Archives — Public domain
