Narrow Trails and a 64-Inch Machine
A 64-inch side-by-side can feel perfectly manageable in the driveway, then become a headache when a trail pinches between trees or a route is posted for narrower machines. In Idaho, the key is matching your machine’s actual width to the route—not guessing from a trail name or map line. This guide explains how to check fit, plan alternatives, and ride narrow trails more comfortably.
What a 64-inch machine means on Idaho trails
Compare your machine’s real width with the route limit
The “64-inch” label is a useful starting point, but it may not tell you the machine’s exact width as you ride it. Tires, wheels, suspension setup, and aftermarket accessories can change the widest point. Measure your machine at its widest fixed point, including anything that sticks out, and compare that measurement with the posted trail restriction or official route information.
A trail marked for machines 50 inches wide or less is not a tight squeeze for a 64-inch UTV; it is a route your machine is too wide to use. Do not treat a posted limit as a target that you can exceed by riding carefully. The limit exists to keep machines compatible with a route’s physical dimensions and use rules.
Also separate a trail’s width restriction from a machine’s advertised width. A vehicle marketed as 64 inches wide may measure differently after modifications, but that does not make it suitable for a 50-inch route. If you are unsure how a restriction applies, check the route’s official information before unloading.
Narrow does not always mean formally width-restricted
A trail can feel narrow without having a specific vehicle-width designation. Trees, brush, rock walls, steep banks, and sharp turns may leave little room to maneuver, even where the route is not officially limited to narrower machines. The reverse can happen too: a route that looks broad on a map may include a short, tight section that becomes difficult for a wide UTV.
For example, a wooded track in the Idaho Panhandle may have branches crowding the route, while an open road in the Boise National Forest may have plenty of visual space but a tight switchback. The important question is not just whether the machine can physically enter. Ask whether it can make the turns, pass other users safely, and avoid leaving the established route when the terrain narrows.
Before choosing a route, review Idaho Trails Rated for Full-Size Rigs and Idaho Trails That Suit a 50-Inch Machine. Those topics can help you distinguish trails intended for larger vehicles from routes where a 64-inch machine is likely to be a poor fit.
Know the difference between a tight trail and a closed route
When a route feels too narrow, it can be tempting to ride around a tree, cut a corner, or widen the track to get through. That can damage vegetation and soil, and it may take you outside the designated route. If your machine cannot pass without leaving the trail or taking an unsafe line, turn around where it is safe to do so.
A tight section is also not a reason to ignore posted signs. Follow route markers and closures, and don’t assume that a route is open to your machine simply because another rider has used it.

How to check whether a route fits before you go
Use official maps and route information
Start with the land manager’s official maps and route information. Depending on where you plan to ride, that may mean checking a Motor Vehicle Use Map, local route information, or posted signs at the trailhead. Look for vehicle-width restrictions, seasonal closures, and routes that are limited to particular kinds of machines. A line on a general recreation map may not include the detail you need to decide whether a 64-inch UTV is allowed.
Apps such as onX Offroad can help you review route options and plan a ride, but use them as a planning aid—not as a substitute for current land-manager information and signs on the ground. Check that the map layer and route details match the area you intend to ride, and compare them with official information before setting out.
This step matters especially when a ride crosses different land jurisdictions or connects several routes. A track that begins on one road may lead to a narrower trail with different restrictions. Look at the route as a whole rather than judging only the first mile.
Plan the full ride, including the return
A route may appear suitable at the starting point but become unsuitable farther in. Check the entire planned route and identify places where a width restriction, narrow segment, or closure could force a change. Also consider whether your group can turn around safely if the trail becomes too tight.
A practical plan includes a primary route, a wider alternative, and a clear turnaround point. If you are riding with friends on smaller machines, agree ahead of time that the group will stay together only where all vehicles are allowed. Don’t let the smaller machines continue onto a restricted trail while the 64-inch UTV follows because “it’s only a short section.”
For navigation, download or save useful map information before you reach areas with weak cell service. onX Offroad may help you keep track of planned routes, but downloaded maps do not replace checking closures or reading trail signs. Learn more about preparation in Reading an Idaho Motor Vehicle Use Map and Checking Idaho Trail Status Before You Drive.
Ask the right questions at the trailhead
At the staging area, check signs and look for updates that could affect your plan. If a posted restriction is unclear, ask the land manager or another official contact rather than relying on another rider’s interpretation. A popular route or a visible set of tire tracks does not prove that a 64-inch machine is permitted.
Be specific when asking for help: give the route name, the machine’s width, and the direction you intend to travel. “Is this trail okay for a UTV?” is less useful than “Is this route open to a machine that measures 64 inches wide, and are there any narrow sections or closures beyond the first junction?”
Carry a backup plan on paper or saved offline. That can prevent a frustrating situation where you arrive at a junction, discover the route is not suitable, and have no safe alternative in mind.
What to expect when riding a wide machine on narrow routes
Turning room can be the bigger challenge
Even if a section is wide enough to pass straight through, bends can be difficult. A long wheelbase and wide stance require room to turn, and a tight switchback may leave little space to maneuver without backing up. Loose gravel, a steep edge, or a drop-off can make that maneuver more stressful.
Approach unfamiliar corners slowly, stay on the established route, and look for a safe place to stop before committing to a turn you cannot complete. If you meet another rider on a narrow section, communicate clearly and use a suitable passing area rather than trying to squeeze past at the edge. On a one-lane route, the safest option may be for one group to carefully back up to a wider spot.
On tight routes in places such as the Boise National Forest or around the Sawtooth region, conditions can vary with vegetation, erosion, and maintenance. A route that felt comfortable on a previous trip may be tighter after brush grows in or a section changes. Treat your memory as helpful context, not a guarantee.
Keep the machine on the trail
A wide UTV can make trail damage more likely if the driver tries to create extra room. Avoid pushing branches aside with the vehicle, driving over vegetation, cutting switchbacks, or widening the trail around obstacles. If the marked route is too tight to use responsibly, turn around and choose another route.
This is not just about appearance. Riding off the established track can damage plants and soil, worsen erosion, and create new paths that other riders may follow. Staying on the route also makes it easier for land managers to maintain and clearly mark the trail.
A useful rule for a group is to stop before a difficult pinch point and decide together. If the driver cannot see a clean line through the section, a passenger can get out in a safe place and help assess it. That does not mean a spotter can make an unsuitable or restricted route acceptable; it simply helps the driver judge an allowed section more carefully.
Choose routes that suit the whole group
A ride is more enjoyable when the route matches the widest vehicle in the group. If one person brings a 64-inch UTV and the rest bring smaller machines, plan around routes that the widest machine can legally and safely use. Avoid building the day around a narrow trail and hoping the larger vehicle will somehow fit.
This may mean choosing a wider forest road or a trail intended for full-size rigs instead of a narrow single-track-style route. Check Idaho Trails for a Full-Size Truck for related planning ideas, and use Finding the Right Motor Vehicle Use Map when you need to verify route designations.
Before leaving, agree on simple group expectations: who leads, where you regroup, and what everyone will do if the route narrows or a closure blocks the planned path. A little coordination can prevent the smaller machines from disappearing ahead while the 64-inch UTV is left searching for a safe way through.
A practical route-planning checklist
Compare the restriction with your measured width
Use this quick comparison as a planning aid. It does not replace posted signs or official route information.
| What you find | What it means for a 64-inch machine | Best next step |
|---|---|---|
| Route is restricted to 50-inch machines | Your machine is too wide for that route | Choose a route that permits your machine |
| Route has a different posted width limit | Compare the limit with your measured width | Confirm the designation with official information |
| No width limit is listed, but the trail looks tight | Physical fit may still be difficult | Review route details and plan a safe alternative |
| Map information and trail signs disagree | Treat the conflict as unresolved | Stop and check with the land manager |
| A route becomes too narrow to ride without leaving the trail | Continuing could be unsafe or damaging | Turn around at a safe location |
Make a simple plan before loading up
- Measure your UTV at its widest point, including relevant accessories.
- Select the intended route and review its width restrictions and access rules.
- Check official maps and land-manager information for closures or seasonal limits.
- Use onX Offroad or another mapping tool to help organize the route, then compare it with official information.
- Choose a wider backup route and identify a safe turnaround option.
- Check trailhead signs before riding, and adjust your plan if the posted information differs.
- Keep the machine on the established route; never widen a trail to make it fit.
It is worth doing this homework before a long tow to a trailhead. Discovering a restriction after unloading is frustrating, particularly when the group has already planned a full day around one route. Checking width and access in advance gives you time to pick a better fit.
For a 64-inch machine, the safest planning assumption is simple: do not use routes designated for narrower vehicles, and do not treat a physically tight trail as suitable just because no width number is immediately visible. Confirm the route, watch for signs, and be willing to change plans. That approach helps protect the trail and makes the ride less stressful for everyone in your group.
