North Dakota Grassland Motor Vehicle Use Maps
A ride across North Dakota’s grasslands can look straightforward on a screen, then turn confusing when a faint two-track meets a closed gate or a route disappears into open prairie. Motor Vehicle Use Maps help show where motorized travel is allowed, but they take some interpretation. This guide explains how to read them, plan a legal route, and avoid common navigation mistakes.
What a Grassland Motor Vehicle Use Map Shows
It is a map of motorized access, not every visible track
A Motor Vehicle Use Map, often shortened to MVUM, is a management map for roads and trails on National Forest System lands. In North Dakota, these maps are especially relevant to the Dakota Prairie Grasslands, including the Little Missouri, Sheyenne, Cedar River, and Grand River National Grasslands. They identify routes that are designated for motor vehicle use and may show restrictions such as vehicle type, seasonal dates, or route-specific conditions.
The distinction between a visible track and an authorized route matters. A worn line across grass may be an old two-track, a ranch access route, or a path made by previous visitors. Its appearance does not establish that the public may drive it. An MVUM helps answer the more useful question: is this route designated for the kind of motorized travel I’m planning, at the time I intend to ride?
A map also has limits. It does not necessarily show every point of interest, campground, local road, private parcel, or non-motorized trail. A route can be legal on the map but still be temporarily affected by weather, maintenance, fire restrictions, or a posted closure. Treat the MVUM as the baseline for designated motor access, then check for additional restrictions before leaving home.
The map is different from a trail map or road atlas
A general road atlas can help you reach the Little Missouri National Grassland from Medora or Watford City, but it may not show the motor-vehicle designations needed to plan a ride on National Forest System land. A recreational trail map may focus on a particular riding area or non-motorized route network. An MVUM has a narrower job: it identifies designated routes and the conditions attached to them.
This is why a route shown on one map may be missing from another. A county road map, a navigation app, and an MVUM can each represent different kinds of access. They are not interchangeable. If a line appears on a phone map but not on the applicable official motor-vehicle map, do not assume it is open to OHVs. Pause and verify the route with the land manager or an authoritative local source.
A useful companion resource is [North Dakota Grassland Roads Open to OHVs], which focuses on the roads and access question from a rider’s perspective. For a broader view of planning across the state, [North Dakota OHV Trail Map Downloads] can help you compare grassland routes with established riding areas. Keep in mind that neither a statewide overview nor an app replaces the current MVUM for the specific grassland unit you plan to visit.
How to Read a Motor Vehicle Use Map
Start with the map area and its legend
Before following a route, confirm that the map covers the right National Grassland and the area where you intend to ride. North Dakota’s grassland units are separated geographically. A map for the Little Missouri National Grassland will not tell you which routes are designated in the Sheyenne or Cedar River units. Check the map title, boundary, legend, publication details, and any notes before using it.
The legend explains how the map represents route types and restrictions. Look for symbols or labels for roads, trails, vehicle classes, seasonal access, and other travel conditions. The wording and symbols are important: a line may represent a route that is open only to certain kinds of vehicles, or only during a stated period. If you cannot confidently interpret a marking, do not guess based on the line’s appearance. Find the map’s written explanation or ask the responsible office.
Pay particular attention to dates and seasonal wording. A route may be designated for use only during a specific part of the year, or its status may depend on a seasonal closure. That can matter in spring, when wet ground is vulnerable to rutting, and during periods when an agency has imposed a temporary restriction. A map’s designation does not mean every route is suitable in every condition.
Match the route to your machine and your trip
Before you go, identify the type of machine you plan to use and compare it with the map’s restrictions. An ATV and a wider side-by-side may not be treated the same on every route. Check any stated vehicle-width, vehicle-type, or route-specific limitation rather than assuming that access for one motor vehicle means access for all. If the machine’s dimensions or classification are unclear, confirm the restriction with the land manager.
It also helps to plan with a specific route in mind rather than treating an entire grassland as open riding country. Mark the entry point, the roads you expect to use, and a reasonable turnaround point. Then check that each planned segment is designated for your machine and open during your visit. This is especially useful around the Little Missouri National Grassland, where a ride based near Medora can involve a mix of public roads, designated National Forest System routes, private land, and closed areas.
For a deeper explanation of symbols, route labels, and common map-reading pitfalls, see [Reading a Grassland Vehicle Use Map]. The core rule is simple: follow the designation that applies to the specific route, not the broad impression created by the surrounding landscape. Wide-open prairie can look like an invitation to roam, but open views do not mean cross-country travel is allowed.
| Resource | What it helps you determine | What it does not establish by itself |
|---|---|---|
| Official Motor Vehicle Use Map | Which designated routes and restrictions apply on the mapped National Forest System land | Whether a temporary closure or local condition has changed since the map was prepared |
| General road map or county map | How to reach towns, highways, and some public roads | Whether a route is designated for OHV use on National Forest System land |
| Trail or recreation map | Where a particular recreation route or area is located | Whether every connecting road is open to your machine |
| Navigation app such as onX Offroad | How to follow a planned route and compare mapped information in the field | Permission to use a route that is closed, private, or not designated for your vehicle |
| Signs and barriers on site | Local instructions, closures, or access boundaries at the location | A substitute for checking the full route and map before departure |
Planning a Legal Ride Across North Dakota Grasslands
Build the route from confirmed access points
A reliable grassland ride starts with a confirmed access point, not a promising-looking track. Choose the road or trailhead you plan to use, verify that it connects to designated routes, and check where the route crosses a boundary or meets a different road system. Around Medora, for example, a route may appear continuous on a phone screen while crossing from a National Grassland route to a county road or private land. Those connections can have different rules.
Use the MVUM to plan each leg of the ride. Write down route names or numbers when provided, note the vehicle restrictions, and identify places where you can safely turn around. Do not rely on a single long loop if a gate, closure, or confusing junction would leave you without a clear alternative. A shorter out-and-back route can be a better choice for a first visit, especially when you are unfamiliar with local access patterns.
Apps such as onX Offroad can be useful for following your position and comparing mapped route information while riding. Download or save the information you need before entering areas with weak service, and keep a paper or offline reference available as a backup. Most importantly, use the app as a navigation aid—not as permission. If app data and the official MVUM appear to conflict, stop and verify the route before proceeding.
Account for private land, gates, and changing conditions
Grassland boundaries do not always match what a rider sees from the seat. Public land can sit beside private parcels, and a route may pass near a fence, gate, ranch entrance, or working field. Stay on designated routes, respect posted signs, and do not cross private property simply because it offers a convenient shortcut. When an access point or boundary is unclear, turn around and check rather than testing the situation.
A closed gate is not an invitation to squeeze around it. Gates may protect livestock, mark a property boundary, or indicate a closure. If a gate is open, that does not automatically mean every nearby track is open to motorized travel. Follow the map and any posted instructions, and leave gates as you find them when access is authorized. For more on permission and boundaries, review [North Dakota Posted Land Rules for Riders] and [North Dakota Electronic Posting Lookups].
Weather can change a route’s condition quickly. After rain, prairie soils may become slick or deeply rutted, and a route that looked manageable from town may be difficult or damaging to travel. Check for agency notices, local closures, and current conditions before heading out. If you encounter a closure sign, barrier, or unsafe section that is not reflected in your planned route, do not ride around it; choose a lawful alternative or return the way you came.
Where Grassland Routes Fit Into the North Dakota Riding Network
Little Missouri and the western grasslands
The Little Missouri National Grassland is a natural starting point for many visitors exploring the western part of the state. Medora and Watford City can serve as practical bases for organizing a trip, but neither town should be treated as proof that every nearby track is open to OHVs. Use the applicable MVUM to identify designated routes, then plan around the route conditions and access points shown for the area.
The landscape can make navigation feel deceptively easy. A rider may see a broad valley, buttes, or a distant road and assume there is a direct route across the prairie. In practice, the legal route may follow a designated road that bends around private parcels, terrain, or management boundaries. Staying on that route protects the grassland and prevents an enjoyable ride from becoming a trespass or resource-damage problem.
If your visit includes the Badlands, separate motorized grassland routes from nearby non-motorized destinations. For example, the [Why North Dakota's Maah Daah Hey Bans Machines] guide explains why the popular trail is not a motorized shortcut. Riders looking for a designated OHV route in the area can also explore [North Dakota Riding Near Medora], while checking the specific route designations and closures that apply to their plans.
Sheyenne, Cedar River, and Grand River units
The Sheyenne National Grassland offers a different setting in the eastern part of the state. Riders approaching from the Lisbon area should check the map for that unit rather than relying on information gathered for the western grasslands. The terrain, road layout, and nearby public access can differ, and a route that is appropriate in one unit does not establish access rules in another.
The Cedar River and Grand River National Grasslands also require location-specific planning. A map for one unit may not cover the roads you intend to use in the other, and local roads can connect to National Forest System routes without sharing the same designation. If your ride crosses between public jurisdictions or approaches a town such as Mott, Hettinger, or Bowman, confirm where one road system ends and another begins. [Sheyenne Grassland Road Riding] and [Cedar River and Grand River Roads] offer more focused context for those areas.
Do not judge a route by distance alone. A short mapped segment can still involve a complicated junction, a gate, a seasonal restriction, or a stretch where there is little room to turn around. Allow time for stops and route checks, especially if you are travelling with a group or operating a side-by-side that needs more space to maneuver. A conservative plan is often more enjoyable than a rushed attempt to cover every road visible on a screen.
Common Map Mistakes and a Pre-Ride Checklist
Mistakes that can lead you off the designated route
One of the most common mistakes is treating every line on a digital map as an open riding route. Mapping products combine different data sources, and some may show roads or tracks without displaying the designation that controls motorized use on a particular piece of public land. Always compare your planned route with the official MVUM and pay attention to the land boundary.
Another mistake is assuming that a route open to one kind of vehicle is open to every ATV or UTV. Restrictions may distinguish between vehicle types or dimensions, and riders may overlook a note tucked into the legend. Check the machine-specific wording before you travel. If your side-by-side is wider than the route’s stated limit, do not assume that a short distance or quiet time of day makes it acceptable.
A third mistake is continuing past a closure because the road still looks rideable. A barrier, sign, or temporary notice takes priority over your earlier plan. The same goes for following another rider’s tracks: someone else’s tire marks do not confirm that the route is legal. When uncertain, stop, review the map, and choose a route you can verify.
A practical check before leaving home
Use this simple sequence before every grassland ride:
- Choose the correct unit. Confirm whether your destination is in the Little Missouri, Sheyenne, Cedar River, or Grand River National Grassland.
- Get the applicable MVUM. Check its title, legend, route designations, and any seasonal restrictions.
- Match access to your machine. Review route conditions that could affect an ATV or UTV, including any stated vehicle-type or width limits.
- Check for closures. Look for current land-manager notices and pay attention to weather-related or temporary restrictions.
- Plan a route and a backup. Mark the access point, intended route, turnaround location, and a lawful alternative if a segment is closed.
- Prepare for limited service. Save the map or navigation information for offline use and carry a backup reference.
- Follow signs in the field. Do not bypass gates, barriers, or posted restrictions because the map or app appears to show a route continuing.
For additional planning context, [North Dakota Cross-Country Travel Is Banned] explains why designated routes matter on grassland terrain. Riders who are uncertain about a specific road can also use [North Dakota Trail Status by App and Phone] as a starting point for checking conditions, while confirming current access with the responsible land manager.
The best grassland map is the one you understand before you arrive. Match the map to the right unit, learn the legend, verify that your machine is allowed, and treat signs and closures as part of the route information. That small bit of preparation can save a long detour, prevent a boundary mistake, and help keep North Dakota’s grasslands open for responsible riding.
