Helena-Lewis and Clark Forest Riding
Planning an ATV or UTV ride in the Helena-Lewis and Clark National Forest can get confusing fast: a road shown on one map may not be open to your machine, and seasonal gates can change a trip plan. This guide explains how to choose a riding area, check legal routes, match your machine to the terrain, and prepare for a remote day out.
Understand the Forest and Its Riding Areas
Think in regions, not one connected trail system
The Helena-Lewis and Clark National Forest covers a wide stretch of central Montana, with riding opportunities spread across separate mountain ranges and communities. Helena, Great Falls, Lincoln, White Sulphur Springs, and other towns can all serve as starting points for different parts of the forest. That does not mean routes connect between them, or that a ride near one community gives you access to the entire forest.
Before choosing a place to unload, identify the specific forest unit or general area you want to explore. A ride in the Little Belt Mountains, for example, is a different outing from one planned near Helena or Lincoln. Distance between trailheads, road conditions, fuel availability, and the kind of terrain can all vary. If you are unfamiliar with the region, begin with a broad overview such as [Montana's National Forest Trail Systems], then narrow your plan to the forest area you can realistically reach.
It also helps to separate “near a town” from “easy to access.” A trailhead may be a substantial drive from town, and the last miles could be on a rough gravel road. Check where the legal route actually begins, whether there is a staging area, and whether your tow vehicle and trailer can handle the approach. A destination name on a map is not, by itself, confirmation that there is a suitable place to park and unload.
Use local communities as planning anchors
Local towns are useful for planning fuel, lodging, food, and the drive to a riding area, but they are not a substitute for checking route rules. Around Helena, start by researching [Helena Area OHV Trails] and the applicable maps for the particular area you have in mind. In the Great Falls region, [Riding Near Great Falls] can help orient your search, while plans focused on the Little Belts can begin with [Riding the Little Belt Mountains].
Use those topics as starting points rather than promises of an open route. A town may be close to several public-land areas, but trail access and permitted vehicle types can differ from one road or trail to the next. For example, a route that works for a narrow ATV may not be open to a wider side-by-side, even if the two routes appear to run through the same general area.
If your group is meeting from different directions, choose a clear rendezvous point before leaving home. A roadside pullout on a public road is not necessarily an authorized staging area, and parking a trailer where it obstructs traffic or a gate can cause problems for other visitors. Confirm the staging location on a current map or with the responsible land office, and share the location with everyone in the group.
Confirm Which Routes Are Open to Your Machine
Read the Motor Vehicle Use Map carefully
The most important planning task is checking the official Motor Vehicle Use Map, commonly called the MVUM, for the area you intend to ride. It shows which designated roads and trails are open to motor vehicles and may include vehicle-width limits, seasonal dates, and other restrictions. Do not assume that a line on a general recreation map, a phone app, or an old GPS track means the route is currently open to your machine.
Learn how to interpret the map before the trip, not at a confusing junction with dust in your eyes and your group waiting. [Reading a Montana Motor Vehicle Use Map] is a useful companion topic, and the relevant forest map should be matched to the specific part of the forest you plan to visit. Pay attention to the route number, the type of route, the permitted vehicle width, and any seasonal language. A route may be open to highway-legal vehicles but not to an ATV, or open to some OHVs but not a full-size UTV.
OnX Offroad can help you organize route research, view mapped routes, and save information for offline use, but treat it as a planning aid rather than the final word on access. Compare what you see in the app with the official MVUM and any current closure notices. If the map and a posted sign appear to conflict, do not ride through and hope the map is right. Stop, follow the restriction on the ground, and confirm the route status with the responsible agency.
Check vehicle width, road status, and seasonal limits
Width is one of the details riders most often miss when planning a UTV ride. “OHV route” does not always mean every OHV can use it. A route may have a width restriction, and machine dimensions can vary with tires, aftermarket accessories, mirrors, or other modifications. Measure your machine as it is actually set up and compare it with the route designation. If your machine is near a stated limit, do not rely on a rough estimate.
Also distinguish a road from a trail. Roads may serve administrative, timber, or local access purposes, while designated motorized trails can have different rules and vehicle limits. Some routes may be open only during certain dates; others may be closed by a seasonal restriction, a temporary order, fire conditions, or maintenance work. A familiar route from last summer is not automatically open this summer.
| Planning detail | What to check | Why it matters |
|---|---|---|
| Route designation | Whether the route is open to motorized use | A visible road or trail is not automatically legal to ride |
| Vehicle width | The posted or mapped width limit and your machine’s actual width | A UTV may not fit the route’s permitted class |
| Seasonal dates | Opening and closing dates shown on the MVUM | Snow, wildlife, or resource protection can affect access |
| Temporary closures | Current forest notices and signs at the route | Conditions or work can change access after a map is printed |
| Staging access | Parking, trailer space, and the legal approach road | A ride can be legal while the planned unloading spot is not suitable |
When you are comparing options for a wider side-by-side, [Montana Trails Rated for Full-Size Rigs] offers useful context, but confirm every route on the relevant forest map. Check [When Montana High-Country Trails Open] as part of seasonal planning, too. Conditions in the mountains can change quickly, and a route that is technically open may still be a poor choice when snow, mud, or runoff makes travel difficult.
Choose a Ride That Fits Your Group
Match the route to machine size and rider experience
A good ride is not necessarily the longest or most rugged one. It is the route your whole group can manage safely, in the machine they brought, with enough time to return before dark. A narrow trail with tight turns may be a poor fit for a wide side-by-side, even if the driver is experienced. An exposed, rocky climb may be stressful for a new rider who expected a relaxed family outing.
Look at route width, surface, grades, turning room, and possible passing areas. A trail that feels comfortable on a compact ATV may be awkward in a larger UTV, especially where trees, rocks, or steep side slopes leave little room to maneuver. Wider machines should not be forced onto narrow routes by riding around obstacles or cutting new lines. If the mapped route does not fit the machine, choose another permitted route.
Be equally honest about the riders. A group with children, first-time operators, or mixed experience should plan conservatively and agree on a turnaround point. The most confident driver may be ready to continue while someone else is tired or uneasy. Decide in advance that anyone can ask to stop, slow down, or turn around without being pressured. For more on choosing a suitable route, see [Montana Trails Suited to Beginners] and [Family-Friendly Montana OHV Trails].
Set a realistic pace and ride plan
Map distance alone does not tell you how long a day will take. A short route can take hours if the surface is rough, the group stops for views, or riders need time to navigate junctions. Add time for unloading, checking permits and equipment, regrouping, meals, and unexpected delays. If you are relying on a particular road to return to the trailer, plan a clear turnaround time rather than counting on the group to “see how it goes.”
Before starting, agree on a few simple group rules. Decide who rides first and who brings up the rear, where you will stop to regroup, and what to do if someone falls behind. Keep riders within sight or use a dependable check-in method at planned junctions. On a narrow route, avoid bunching up so tightly that dust, rocks, or abrupt braking create a hazard for the next person.
A route app can help the group follow a planned track, but do not let a colored line overrule a closed gate or a posted restriction. OnX Offroad can be helpful for saving maps and reviewing possible route connections before you leave, particularly when phone service is unreliable. Download your planned area and check that you can use it offline. Carry a separate way to navigate as well, because a phone can lose power, overheat, break, or become difficult to read in bright sun.
Prepare for Changing Conditions and Remote Travel
Check access before you load the trailer
A route can be shown as part of a riding network and still be unavailable on the day you arrive. Seasonal closures, active work, fire restrictions, washouts, snow, and other conditions can affect access. Before driving to the trailhead, check the forest’s current notices and any applicable orders. Then look for signs at the entrance and junctions when you arrive. A map review at home and a final check on the ground are both worthwhile.
Make your check specific to the area and the date of your trip. A notice for one district or road may not apply to another, and a general forest page may not answer every local question. If an access detail is unclear, contact the responsible forest office before setting out. This is especially useful when your plan depends on one narrow route, a particular staging area, or a seasonal opening. [Checking Montana Trail Status Before You Drive] covers the broader habit of confirming conditions ahead of time.
A backup plan prevents an uncertain gate from turning into a wasted weekend. Choose another legal riding area or a shorter route that is within the same general region, and verify that it suits your machine as well. Do not improvise by following an unsigned track around a closure. A locked gate may protect a work zone, wildlife habitat, private property, or a route that is not open to motorized travel.
Pack for limited service and a longer day than expected
Cell coverage can be inconsistent in mountainous and remote parts of central Montana. Tell someone where you plan to ride, where you expect to park, and when you will check in. Give that person instructions about what to do if you do not make contact by the agreed time. This simple step matters even on a ride that feels close to town: a mechanical problem or injury can turn a short outing into a long wait.
Carry navigation that works without a cellular connection, along with enough food, water, warm layers, and basic repair supplies for a delay. A tire plug kit or other repair gear is only useful if someone in the group knows how to use it. Consider the conditions at elevation, not just the temperature in Helena or Great Falls when you leave. Wind, shade, rain, and an unexpected stop can make a warm-weather ride feel cold quickly.
Your gear should reflect the machine and terrain. Secure tools and supplies so they cannot shift, interfere with controls, or fall onto the trail. Carry a first-aid kit suited to your group, a light source, and a way to signal for help. [Cell Service in the Montana Backcountry] and [What to Carry on a Remote Montana Ride] can help you think through those preparations. If your route is particularly remote, consider whether your group has a reliable emergency communication plan before committing to it.
Ride Responsibly and Protect Access
Respect closures, signs, and other forest users
Stay on designated routes and do not widen a trail to get around a muddy patch, fallen tree, or parked vehicle. Going around an obstacle can damage vegetation and soil, and it may create a new unauthorized track. If a route is blocked or appears unsafe, turn around when you can do so without creating additional damage. Report the issue through the appropriate forest contact rather than clearing or bypassing it yourself.
Expect to share roads and recreation areas with hikers, horseback riders, bicyclists, wildlife, and other motorized users. Slow down where visibility is limited, near trailheads, and whenever you approach other people. Give riders and pedestrians enough space, keep noise down near homes and campgrounds, and avoid spinning tires on loose soil. Dust can be unpleasant for others and may obscure the road for the person riding behind you.
Watch for signs that indicate a boundary, a route restriction, or a change in permitted use. A forest boundary does not mean that every road on both sides is open to the same vehicles. Routes can pass near private property, other public-land jurisdictions, or areas with different rules. If you are unsure whether a road continues legally, stop and check the map or posted information instead of treating the most obvious track as the right one.
Leave a clear, low-impact staging area
At the trailhead, park and unload without blocking gates, road access, turnarounds, or space needed by emergency and maintenance vehicles. Keep tie-downs, ramps, and loose equipment organized so they do not spread across the parking area. If a lot is crowded, do not assume that a roadside shoulder is an acceptable overflow spot. Use a designated area or choose a different time or staging location.
Before leaving, check that your machine is ready for the route: tires, brakes, steering, lights where needed, fuel, and any cargo attachments should be secure. Confirm that everyone has the necessary permits or required documents for their circumstances, and that the route they plan to ride matches the machine they are operating. For broader trip planning, [Montana Trailhead Parking and Staging] offers additional context about unloading and parking.
When you return, remove all rubbish and inspect the area for anything that fell from the machine or trailer. If your group has created a muddy rut or disturbed a campsite while turning around, do not make it worse by repeatedly driving over it. Good trail behavior helps protect the places people come to enjoy and keeps relationships with local communities and land managers constructive. The forest is large, but trail access depends on many individual choices made on ordinary riding days.
