Montana Trails That Suit a 50-Inch Machine
A 50-inch side-by-side can open up more riding options than a full-size UTV, but “50-inch” does not mean every Montana trail is suitable or open. The hard part is matching your machine to the exact route, then checking its width designation, seasonal status, and access rules before you unload. This guide explains how to do that and where to begin looking.
What “50-inch trail” means for Montana riders
A machine’s width is only one part of the fit
A trail marked or described as suitable for machines up to 50 inches wide has a width constraint, but that label is not a universal pass to ride every route in the area. Trails can have different designations, and access may change at a junction or where a route enters land managed by another agency. A nearby wide road does not automatically make a narrower trail legal for your machine.
Check your UTV’s actual width, not just the model name or a brochure description. Tires, wheel spacers, fender extensions, mirrors, and other modifications can affect the widest point. If the machine is close to the limit, measure it from the outside edge of the widest components. A tight fit on paper can turn into a stressful squeeze between trees, rocks, or trail markers.
Also distinguish trail-width restrictions from a trail’s physical character. A route can be wide enough for your machine and still be steep, rocky, muddy, exposed, or difficult to turn around on. A narrow trail does not necessarily mean an easy trail, and a machine that fits may still be a poor match for a rider’s experience or the day’s conditions.
Confirm the route, not just the riding area
Montana riding areas often contain a mix of trail types, forest roads, and routes with different restrictions. A map label for a trail system is useful for planning, but it does not settle whether a particular route is open to a 50-inch vehicle. Follow the route-specific information on the applicable Motor Vehicle Use Map, commonly called an MVUM, and check any posted closure notices or local land-manager updates.
Pay close attention to route numbers and junctions. It is easy to assume that a loop remains suitable because its first section is marked for a narrow machine. At a fork, the route may continue onto a road or trail with a different designation. Keep a paper map or downloaded map available so you can check where the route actually goes, especially where cell coverage is unreliable.
A navigation app such as onX Offroad can help you study route connections and keep track of your location, but use it as a planning aid rather than a replacement for official travel rules. Compare the route on the app with the current MVUM and signs at the trailhead. For more on route maps, see [Reading a Montana Motor Vehicle Use Map] and [Finding a Forest's Motor Vehicle Use Map].
Montana riding areas to research for a 50-inch machine
Flathead National Forest and the Flathead Valley
Riders near Kalispell, Columbia Falls, and Hungry Horse may start by researching the Flathead National Forest and nearby riding opportunities. The region’s varied terrain makes it particularly important to check individual routes. A route that looks like a gentle forest track on a map may have a narrower segment, a steep grade, or a seasonal restriction that matters to your group.
Use the forest’s official maps to identify routes that allow your vehicle type and width. Then look closely at access points, connectors, and the route’s full length. Do not assume a trailhead name or a broad description of an area tells you which specific trails are appropriate for a 50-inch machine. For background on the area, [Riding Montana's Flathead National Forest] and [Flathead Forest Trails Open to ATVs] are useful related topics to explore.
The best plan is to choose a primary route and a shorter alternative before leaving town. If weather turns wet or a trail is more technical than expected, a nearby forest road or approved route may give you a practical way to shorten the day. Avoid treating an unmarked spur as an escape route unless maps and signs show that it is open to your machine.
Missoula, Bozeman, and Helena area options
Around Missoula, Blue Mountain Recreation Area is a recognizable place to research. It can be tempting to plan around a well-known trailhead and assume the whole network suits a 50-inch vehicle, but the ride should be built around individual route designations. Verify the route you intend to use, including any connectors needed to reach a loop. The related guide [Blue Mountain Recreation Area Near Missoula] can help you continue researching that area.
Near Bozeman, look into the Custer Gallatin National Forest and its riding opportunities, while checking the current map for the particular trail or road. The area’s elevation and changing conditions can affect ride difficulty as well as access. Near Helena, the Helena-Lewis and Clark National Forest is another place to investigate, but do not treat a forest name as a blanket indication that 50-inch machines are allowed across its routes.
The following table is a starting point for research, not a list of guaranteed open trails. Use the managing agency’s route information to confirm whether your machine is allowed on the specific segment you plan to ride.
| Area to research | Useful planning question | What to verify before unloading |
|---|---|---|
| Flathead National Forest | Which mapped routes are open to a machine of your width? | Route designation, junctions, seasonal status, and current closures |
| Blue Mountain near Missoula | Does the planned loop remain on routes open to your vehicle? | Trail connections, signs, and the applicable map |
| Custer Gallatin area near Bozeman | Is the intended route open at the elevation and time of your trip? | Route number, seasonal restrictions, snow or mud conditions |
| Helena-Lewis and Clark area | Does the route match your width and experience level? | Vehicle allowance, route surface, and access conditions |
| A local trailhead or staging area | Is parking and staging available for your trailer and machine? | Posted rules, road access, and designated parking |
How to plan a ride that fits your machine and your group
Build a route around width, ability, and turnaround options
Start with the machine, then choose the ride. Confirm its width and passenger capacity, and consider the experience of everyone in the group. A route that seems manageable for an experienced driver may feel very different to someone on their first mountain ride. If you are riding with children or less experienced drivers, choose a route with room to stop, regroup, and turn around safely.
Look at the route’s length and elevation as well as its width. A long trail with no convenient exit can be a poor choice for a group with limited fuel, a late start, or uncertain weather. Review the route on a map before the trip and identify junctions where you can shorten the day without leaving an authorized route. This is especially helpful in Montana, where a minor change in weather can make a comfortable two-track much more demanding.
Do not force a narrow machine through a route that looks barely passable. If the trail pinches between trees or has an obstacle that would require scraping, lifting, or driving off the marked route, turn around if it is safe to do so. The temptation to “just get through” can cause vehicle damage, trail damage, or an unsafe situation for the rest of the group.
Check access, weather, and trail conditions
Route legality and trail conditions are separate questions. A route can be open to a 50-inch vehicle but still be a poor choice after heavy rain, spring runoff, or a late-season snowstorm. Muddy ground is particularly vulnerable to deep ruts. If a trail is wet enough that your tires are cutting into the surface, consider a different route rather than turning one ride into lasting damage.
Before driving to a trailhead, check for closure notices and seasonal restrictions from the relevant land manager. Review signs at the staging area too; they may reflect restrictions or local conditions that you did not see during trip planning. For more detail on timing and conditions, explore [When Montana High-Country Trails Open], [Trail Conditions After Snowmelt], and [Checking Montana Trail Status Before You Drive].
Plan for limited communication. Cell coverage can disappear once you leave a town or paved highway, so share your intended route and return time with someone who is not riding. Carry enough water, food, warm layers, and basic repair or recovery equipment for a longer day than planned. A map or downloaded navigation route is useful, but keep a backup option in case a phone battery runs low or a route is blocked.

Before you leave home
A little preparation can prevent the familiar trailhead scramble: one person looking for the map, another wondering whether the route is open, and everyone waiting while a trailer blocks the staging area. Confirm your destination, route, trailhead access, and parking plan before departure. Make sure the trailer and tow vehicle can reach the staging area without relying on a road that may be rough, narrow, or restricted.
Check the machine itself. Look over tires, brakes, steering, lights, belts, fluids, and tie-down points. Carry a tire repair kit and tools suited to the machine, along with a first-aid kit and a way to communicate if your phone has no service. The right equipment depends on the trip, but the point is to be prepared for a delay rather than assuming every small problem can be fixed quickly.
Keep a paper map or a reliable offline map available. If you use onX Offroad to plan or navigate, download the area before leaving service and confirm the planned route against official route information. Let the group know the plan and agree that riders will stay together or regroup at clearly identified junctions.
At the trailhead and on the route
Read posted signs before unloading or starting the ride. Confirm that the intended route is open to your machine and note any restrictions. If signs differ from what you expected, follow the posted direction and reconsider the plan. A map saved on your phone is not a reason to ride past a closure or onto a route that does not allow your vehicle.
Keep a pace that leaves room to react to blind corners, loose rock, livestock, other trail users, and changing surfaces. On narrow sections, leave enough distance between machines to avoid dust and give the lead rider room to stop. At junctions, regroup and verify the next segment rather than letting the group scatter onto different routes.
Respect the route edges. Do not widen a trail to pass an obstacle, drive around a closure, or use an unmarked shortcut. If the trail is too narrow or difficult for your machine, turning back is a valid decision—not a failure. For more on choosing routes suited to machine size, see [Montana Trails Rated for Full-Size Rigs] for a useful contrast and [Montana Trails Suited to Beginners] if your group wants a less demanding outing.
Common mistakes to avoid when choosing 50-inch trails
Assuming a machine’s advertised width guarantees access
“50-inch machine” is a helpful starting point, but riders can overlook accessories, tires, and modifications that add width. Measure the actual vehicle and compare it with the applicable route restriction. If you have a vehicle close to a stated limit, do not rely on an informal description from a social post or an old ride report.
Another common mistake is treating an area as a single continuous trail network with one set of rules. Forests, land boundaries, route designations, and closures can all change the conditions of a ride. Check every route segment that matters to your plan, including the road or trail used to reach the main riding area.
Old information can also be misleading. A route someone rode last summer may be closed now, have a seasonal restriction, or have changed after damage or maintenance. Use trip reports for context about terrain, not as proof of current access. Confirm route status and restrictions with the responsible agency before setting out.
Treating a map line as a promise of an easy ride
A thin line on a screen says little about how a route feels behind the wheel. It may climb sharply, cross loose rock, or become rutted after rain. Give yourself room to adjust the plan and avoid scheduling the day so tightly that turning around feels like a problem.
Likewise, a narrow-machine trail can still challenge an experienced rider. A 50-inch width designation does not promise a smooth surface, easy grades, or frequent places to pass. Be realistic about your group’s experience, vehicle condition, daylight, and the possibility of delays.
Finally, do not ride beyond a signed boundary or onto a route simply because it appears to connect with your planned loop. Keep the group on routes that are clearly open and appropriate for the machine. If a junction is unclear, stop and check the map rather than guessing. A thoughtful change of plan is far better than having to explain an avoidable access problem—or recover a stuck machine—at the end of a long day.
