Wyoming’s 8,000 Enrolled Forest Miles
Wyoming’s enrolled forest routes can make an ATV or UTV trip feel wonderfully open—but “enrolled” does not mean every road is open to every machine, in every season. The challenge is matching your route, vehicle width, permit, and current land-manager rules before you unload. This guide explains how the state’s roughly 8,000 enrolled forest miles fit together and how to plan a ride responsibly.
What Wyoming’s Enrolled Forest Miles Mean
Enrollment is a program, not a promise of unrestricted access
Wyoming’s enrolled forest miles are routes on National Forest System lands included in the state’s trails program. The program supports designated motorized access, but enrollment alone does not establish that a route is open to every vehicle or rider. A road or trail may have restrictions based on season, vehicle width, maintenance, wildlife concerns, or other land-management decisions.
That distinction matters when you’re planning a weekend ride. A route shown in a broad overview of the state’s enrolled miles could be closed for part of the year, restricted to narrower machines, or subject to a temporary closure. Treat enrollment as a starting point for research—not as a substitute for checking the route’s current status and rules. [Wyoming's Enrolled Roads and Trails]
The scale can be appealing, especially if you’re used to riding in a small local area. But thousands of miles across different forests do not form one continuous trail system with identical rules. A route near Buffalo may have different conditions and seasonal access from a road near Laramie or Pinedale. Plan around the specific forest, district, and route you intend to ride.
Enrolled does not mean open to every kind of machine
A National Forest road may be suitable for a wider side-by-side while nearby trails are limited to narrower vehicles. Some routes are roads rather than trails, and their surface, traffic, and operating conditions can feel very different. A wide UTV might fit physically but still be prohibited on a route with a narrower vehicle limit. Conversely, an ATV may be allowed on a road that feels rougher or more exposed than a dedicated trail.
Pay attention to signs at the trailhead and at route junctions. A map can show where a route runs, but the posted restriction may determine what you can ride there. This is especially important around networks with both roads and narrow trails, such as parts of the Medicine Bow and Bighorn National Forests. [Which Wyoming Trails Are Held to 50 Inches]
Before leaving home, identify the route type, any width rule, and the vehicle categories allowed. If a route description is vague, call the relevant forest office rather than assuming the most permissive interpretation. The few minutes spent confirming access can prevent a long detour—or a citation—once you’re on the ground.
How to Find Routes You Can Actually Ride
Start with the forest’s travel management information
A useful route search begins with the National Forest or ranger district that manages the area. Look for its motor vehicle use map, often called an MVUM, and any companion travel-management information. These resources help show which roads and trails are designated for motorized use, what vehicle types are allowed, and when seasonal restrictions apply.
The key is to match the map to the exact area you’ll visit. If your plan is to ride near Buffalo, focus on the relevant Bighorn National Forest information, not a general Wyoming map. For a trip near Laramie, check the applicable Medicine Bow routes. A boundary line on a map may separate areas with different rules, and a familiar road can change status where it crosses into another management unit. [Wyoming Trail Maps and MVUMs]
Digital mapping tools can help you visualize a route and keep track of junctions. Apps such as onX Offroad may be useful for trip planning, but don’t treat any app as the final authority on legal access. Compare its route information with the land manager’s official map and current notices. Save the information you need before traveling; cell service can disappear quickly once you leave town.
Read both the route designation and the closure information
A map may show a route as designated for motorized use while another notice specifies that it is closed during a particular season. These details are not contradictory: one describes the route’s permitted use under certain conditions, while the other describes when those conditions allow riding. Seasonal closures may protect wildlife, reduce damage from wet ground, or reflect snow and maintenance conditions.
If a route is marked open on a general map but a current sign at the trailhead says closed, do not ride past the sign. A posted closure can reflect a recent change that a printed or downloaded map does not show. On the other hand, if a digital map seems to show a closure but the official information is unclear, pause and confirm with the managing office instead of guessing. [When a Map and a Sign Disagree]
Build a little flexibility into your plan. Pick a primary route and one or two legal alternatives in the same general area. That way, a closed road or muddy trail does not force you into an unauthorized shortcut.

| What to check | Why it matters | Where to confirm |
|---|---|---|
| Route designation | Shows whether motorized use is allowed | Forest travel map or MVUM |
| Vehicle width or type | A route may exclude wider machines or certain classes | Map legend, posted signs, land manager |
| Seasonal dates | Access can change with wildlife, weather, or ground conditions | Current forest notices and route signs |
| Temporary closures | Fire, damage, or maintenance can alter access | Trailhead notices and forest office |
| Permit requirements | A state permit may be required even when a route is open | Wyoming permit information and land manager guidance |
Choosing a Forest and Planning a Ride
Match the area to your machine and experience
The right riding area depends on more than the number of miles available. Think about your machine’s width, ground clearance, tires, fuel range, and how comfortable you are with steep grades or remote terrain. A beginner on a small quad may prefer a clearly designated road or a wider, easier route close to a staging area. A group on side-by-sides needs to verify that the trails they choose allow their vehicle width.
The Bighorn National Forest offers a very different feel from routes in the Medicine Bow National Forest. Conditions can vary by elevation and exposure even within one forest. A route that seems straightforward on a screen might involve rough surfaces, sharp turns, creek crossings, or long distances without services. Check the route length and access points, then be honest about the slowest rider and least capable machine in your group.
Use local trail information to narrow your options, then verify each candidate route against official maps. For a wider view of route planning across federal lands, [Wyoming Rules on National Forest Ground] and [Wyoming Rules on BLM Ground] are useful related reads. Remember that a route network can cross land-management boundaries; the rules can change along with the boundary.
Plan around weather, elevation, and distance
Wyoming weather can change quickly, and forest roads may behave very differently after rain or snowmelt. A dry-looking route on a map can become slick, rutted, or muddy after a storm. At higher elevations, snow can linger after lower routes have become comfortable to ride, and a warm day in town does not guarantee good conditions in the mountains.
Distance also deserves more attention than a simple mileage estimate. A slow, rocky route can take far longer than a maintained road of the same length. Add time for stops, navigation, lunch, mechanical checks, and the possibility of turning around. If your group is traveling far from a trailhead, agree in advance on a turnaround time rather than letting the day stretch until you’re racing fading light.
Prepare for limited services. Carry water, food, basic tools, a tire repair option suited to your machine, and a way to navigate when your phone has no signal. Tell someone where you intend to ride and when you expect to be back. For trips at elevation, think about how the altitude, cool temperatures, and exposed afternoon weather may affect the riders as well as the machines.
Seasonal Access and Trail Conditions
Why forest routes may close or open at different times
Seasonal access is a routine part of forest riding, not an unusual exception. Spring closures can protect wet roads and trails from damage or allow wildlife habitat to recover from winter impacts. Snow and lingering drifts can also make some routes inaccessible, even when nearby roads are clear. In autumn, weather and wildlife management may again affect where and when motorized travel is allowed.
These changes can happen at different times across Wyoming. A low-elevation route may be usable while higher roads remain snowbound. A route may open later than you expect because of muddy conditions, maintenance needs, or a local management decision. If you’re traveling from out of town, check conditions close to your departure date and again before unloading. [Why Bighorn Trails Close in Spring]
Do not assume that a route’s usual seasonal pattern guarantees access on your planned date. Fire activity, storm damage, maintenance, or other temporary events can change access. If you see a barrier, closure sign, or fresh notice at the entrance, follow it. Riding around a barrier can damage sensitive ground and make a bad day much more expensive.
Keep a backup plan for closures and changing conditions
A practical forest trip includes a legal alternative, not just a single route. Before you go, find another route or riding area that suits your group and machine. Check whether it requires a different permit, has a width restriction, or is managed by another agency. A backup plan is only useful if you confirm it is actually available to you.
Suppose your group arrives near the Snowy Range and discovers the route you wanted is still closed. The tempting option may be to follow visible tracks around a gate. Don’t. Instead, check current forest information, contact the local office if needed, and choose a route that is designated and open. If no suitable route is available, changing plans is frustrating, but it is better than creating damage or risking a citation.
Weather can require a backup plan while you’re already riding. Set a turnaround point before you leave, and make sure everyone understands that the group will turn around if conditions worsen. A creek that was easy to cross earlier may rise, a storm may move in over an exposed ridge, or a route may become too slick for the least experienced rider. [Wyoming Trails Closed by Snow] offers additional context for planning around winter and shoulder-season access.
Permits, Responsible Riding, and Final Checks
Confirm permit rules before you unload
An open route and a valid state permit are separate questions. Wyoming’s off-road permit rules apply to qualifying machines using designated public routes, and a permit from another state should not be assumed to replace Wyoming’s requirement. Confirm what applies to your vehicle and trip before you arrive at a trailhead. [Wyoming ORV Permits Explained]
This is easy to overlook when you’re focused on the route, especially if you’re visiting for a short trip and your machine already carries a home-state sticker. Check the state’s permit guidance and make sure the decal is properly displayed if one is required. Keep any relevant purchase confirmation accessible, but don’t assume that a receipt alone substitutes for a required decal or other compliance step. [Riding Wyoming With an Out-of-State Sticker]
Permit rules are only one part of preparation. Check whether your machine meets equipment requirements for the area, including spark-arrester and sound rules where applicable. If you’re riding with children, passengers, or a rental machine, confirm the relevant age, passenger, and rental requirements as well. A bit of advance checking is much easier than trying to solve a paperwork problem at the trailhead.
Ride in a way that protects the route for everyone
Stay on the designated route, even when a side track looks like an easier way around mud or a fallen branch. Leaving the route can widen damage, disturb vegetation, and create new tracks that other riders may mistakenly follow. If an obstruction makes the route impassable, turn around or contact the responsible office for advice rather than making your own bypass.
Be considerate of other forest users. Slow down near hikers, horseback riders, campsites, and trailheads, and give people space to move safely. Close gates behind you if they were closed when you arrived. Keep noise under control, pack out your rubbish, and avoid spinning tires or accelerating hard on fragile surfaces. Good trail behavior is not just etiquette; it helps protect continued access.
Before leaving, do a simple final check: route status, route width, seasonal dates, permit, fuel, weather, maps, and a realistic return time. For more route-planning context, [Carrying a Travel Management Map in Wyoming] can help you think through what to have on hand when cell service is limited. And if you’re not sure whether a particular road is enrolled or open, ask the responsible forest office rather than relying on a guess.
