Bighorn Roads Closed Until June
Spring can make the Bighorn Mountains look ride-ready before the roads actually are. Snow, muddy ground, lingering drifts and seasonal restrictions can keep some routes closed well into early summer, while lower roads may open sooner. This guide explains why Bighorn roads may remain closed until June, how to check a route before you leave, and what to do when maps and signs seem to disagree.
Why Bighorn roads can stay closed into June
Snowmelt and saturated roads
The Bighorn Mountains cover a wide range of elevations, and spring arrives at different times across the forest. A road that is mostly clear near a lower trailhead can still have deep snow or icy patches higher up. Even after the snow melts, the ground beneath it may be too soft to support vehicle traffic without damage.
That distinction matters on an ATV or UTV. A route may look passable from the first few hundred yards, but thawing soil can quickly turn into slick mud, deep ruts or standing water. Driving through those conditions can damage the road and surrounding ground, and a route that looks open on a digital map may still be subject to a seasonal closure or temporary restriction.
The opening of a road is therefore not determined by the calendar alone. Weather, elevation, road condition and land-management decisions all affect access. A June trip may be reasonable for one area and too early for another, especially after a heavy snow year or a prolonged cold spring.
Closures protect roads, wildlife and other visitors
Seasonal closures help prevent vehicles from cutting into soft roads and trails. Ruts can channel water, worsen erosion and make the route harder to maintain. In the Bighorns, spring conditions can change quickly, so a closure may remain in place even when a nearby road appears dry.
Managers may also restrict access to protect wildlife or respond to local conditions. A route can be closed for a particular stretch of time, for a specific activity, or until conditions improve. That is why it is risky to assume that one general “opening day” applies to every road in the forest.
For a broader look at how timing affects access across the state, see [Bighorn Forest Roads and Wyoming's Season] and [Why Bighorn Trails Close in Spring]. The key practical point is simple: treat the closure information for the exact route as more important than a general expectation that “the Bighorns open in June.”
Not every road opens at once
“Closed until June” is useful shorthand, but it should not be read as a promise that every Bighorn road opens on the first day of June. Some routes may become accessible earlier, while higher-elevation roads can remain blocked by snow or muddy conditions after lower areas have dried out. Temporary closures can also be added or extended.
This can be frustrating when you have already booked a campsite, arranged time off or hauled your machine across Wyoming. It helps to plan around a general area rather than build the entire trip around one road. If the intended route is still closed, a lower-elevation alternative may be possible—but only if that alternative is also open to the type of vehicle you are bringing.
Before setting a date, check the seasonal and temporary restrictions for the specific routes you hope to ride. [Wyoming Trails Closed by Snow] and [Wyoming Trail Closures to Check First] are useful starting points for thinking through spring access, but always confirm the details for the route and travel date.
How to check a Bighorn road before riding
Start with official route information
Check the current Forest Service travel information for the area you plan to visit. Look for the motor vehicle use map, seasonal designations, closure orders and any road or trail notices. A motor vehicle use map, often called an MVUM, can show which routes are designated for motorized use and when seasonal restrictions apply.
Pay attention to the legend and date range rather than scanning only for a road name. Some designations apply to a particular vehicle class or season, and a road being visible on a general map does not automatically mean it is open to an ATV or UTV. If a closure order covers the route, follow the order even if another map displays the road.
Digital mapping tools can help you plan and understand how routes connect. For example, onX Offroad can be useful for viewing route options and organizing a ride, but use it as a planning aid—not as a substitute for official access information. Check the applicable agency map and current notices before you unload your machine.
Check again close to departure
Conditions can change between the time you plan a trip and the day you ride. Check route information again shortly before leaving, especially in spring. If you are traveling from Buffalo, Sheridan or another town outside the forest, a quick check before you tow can prevent a long drive to a closed gate.
Keep more than one possible route in mind. A primary road may still have snow, while another route at a different elevation could be open. Do not assume, though, that a nearby road is an acceptable backup until you verify its designation and restrictions. A route that looks like a convenient connector may cross land where motorized travel is not allowed.
A useful pre-trip checklist is:
- Identify the exact road or trail names you want to ride.
- Check the official MVUM and any relevant seasonal dates.
- Look for current closure orders, alerts or local notices.
- Confirm that the route allows your machine and intended use.
- Recheck conditions close to departure.
- Carry an up-to-date map or save reliable route information for offline use.
For help interpreting route maps, read [Reading a Wyoming Travel Management Map]. If you use onX Offroad to plan, compare the route with official information before treating it as rideable.
Treat signs and gates as important information
A sign on the ground can alert you to a closure or restriction that is not obvious from a map. If a road is marked closed, do not ride around a gate, move a barrier or continue because the track appears dry. Restrictions can apply to a specific segment, and passing the sign may put you beyond the legal route.
If a map appears to show a route as open but a posted sign says it is closed, do not treat the map as permission to proceed. Stop and verify the current restriction with the responsible land manager. Signs may reflect a temporary closure, a recent change or a route-specific condition that a general map does not show. See [When a Sign on the Ground Says Closed] for more on handling that situation.
When you are uncertain, ask the local Forest Service office for clarification before riding. Be ready to give the road name, nearby junction or trailhead, and the date you plan to travel. “Are the Bighorns open?” is difficult to answer accurately; “Is this named road open to an ATV this weekend?” is much more useful.
Planning a spring ride around closures
Choose a lower-elevation backup
Spring planning is easier when you build in flexibility. If the route you want is at higher elevation, consider a backup in a lower area, but confirm its status independently. Lower elevation does not guarantee open access: a road may still be muddy, seasonally closed or restricted for another reason.
Keep your backup realistic. Check how far it is from your starting point, whether the access road is suitable for your trailer and tow vehicle, and whether the riding area offers routes that match your group’s experience. A quick alternative on a map may turn into a long detour once you are on the ground.
The best backup is one you have checked before the trip, not one you invent at a closed gate. Mark a few legitimate options in advance and note where each begins. A planning app such as onX Offroad can help you keep possible routes organized, while official maps and notices help confirm whether those routes are designated and open.
Match the ride to spring conditions
Even when a road is open, early-season conditions may make it a poor choice for your group. Mud can reduce traction, and snowmelt may leave water across a road or create soft shoulders. A road that was straightforward in late summer can feel much more demanding during a wet spring.
Think about the least experienced rider in your group and the limits of your machine. A narrow, muddy section or a steep, rutted climb can become stressful quickly. If you encounter a stretch that looks unsafe or is causing damage, turn around rather than pushing farther. The ability to reverse course is part of a good spring plan.
Pack for changing mountain weather, too. A sunny start does not guarantee a warm day at higher elevation. Bring layers, water, food, basic repair items and a way to navigate if cell coverage is unreliable. Tell someone where you intend to ride and when you expect to return.
Plan your access from Buffalo or Sheridan
Buffalo and Sheridan are practical starting points for trips into the Bighorn area, but the roads you use to reach a riding area may have different conditions from the trails you intend to ride. Check both the approach and the riding routes. A clear highway does not mean a forest road is open, and an open trail does not help if the access road is blocked or unsuitable for your trailer.
Give yourself enough time to adjust the plan after arriving. If conditions are poor or a closure is posted, do not let the effort of getting there pressure you into riding somewhere unauthorized. A short, safe ride on an open route is better than risking a citation, damaging a muddy road or getting a vehicle stuck far from help.
These local guides can help you think through access and trip planning: [Riding the Bighorns From Buffalo] and [Riding the Bighorns From Sheridan]. Use them alongside current route information, since seasonal access can vary by road and conditions.
| What to check | Why it matters | What to do |
|---|---|---|
| MVUM and route designation | Confirms whether a route is designated for motorized use and may show seasonal limits | Check the correct map and legend for your area |
| Closure orders and notices | A temporary restriction may not be obvious on a general map | Review current agency notices before leaving |
| Signs, gates and barriers | On-the-ground restrictions may apply to a specific road segment | Stop and follow the posted closure |
| Snow and road conditions | A route can be difficult or damaging even when nearby areas are clear | Be prepared to turn around or use a verified alternative |
| Vehicle and route fit | Some routes may have limits or conditions that do not suit every machine | Confirm the route is appropriate for your ATV or UTV |
Common mistakes to avoid
Assuming June means every road is open
A date can help with general planning, but it does not replace checking a specific route. Roads at different elevations can thaw at different times, and an agency may keep a road closed after the snow has receded if the ground is still vulnerable. Avoid treating the first week of June as a universal opening date.
Instead, build a flexible itinerary and confirm each route close to departure. If a particular road is the main reason for the trip, make sure you have a second option that is open and suitable. This small step can save a vacation day from turning into a frustrating search for somewhere else to ride.
Trusting a map layer without checking its limits
A route displayed in a navigation app may be useful for orientation, but the map alone may not tell the whole story about seasonal dates, temporary restrictions or vehicle-specific access. onX Offroad and other planning tools are most helpful when you use them alongside official route information, not in place of it.
Before relying on a route, confirm its designation, seasonal status and any current closure. Keep the map’s limitations in mind while riding, too: a digital route line is not permission to cross a gate, leave a designated road or continue past a closure sign.
Riding through mud because the road looks passable
A road can appear firm at the entrance and become soft farther in. Driving through muddy ground may deepen ruts, damage the road and make it harder for other users to pass. It can also leave you stuck, especially if you are towing a machine or traveling without another vehicle nearby.
If the road is visibly soft, waterlogged or blocked by lingering snow, do not assume that more throttle will solve the problem. Turn around where it is safe to do so. Spring access requires patience, and waiting for better conditions is often the most responsible choice.
Treating a closed gate as a suggestion
A closed gate or posted sign is not a challenge to work around. Do not bypass it by riding beside it, taking an unmarked side track or crossing private ground. Closures can protect the road, wildlife, nearby property or other visitors, and ignoring them can affect future access.
If the reason for a closure is unclear, ask the land manager rather than guessing. This is especially important when maps and signs seem inconsistent. The safest approach is to pause, verify the route status and choose an open alternative if you cannot confirm access.
