Reading a Black Hills Travel Map
A Black Hills travel map can look straightforward until a dotted line, route number, or seasonal note leaves you wondering whether your ATV or UTV is actually allowed there. This guide explains how to read the map’s symbols, check route limits and closures, and plan a ride around places such as Deadwood, Spearfish, Hill City, and Custer without mistaking a tempting line for an open route.
Start with the map type and the land manager
Know what your map is showing
“Black Hills travel map” can mean several different things: a general road map, a recreation map, an app with off-road layers, or a Motor Vehicle Use Map, often called an MVUM. They can look similar while answering different questions. A general map helps you get oriented; an MVUM is designed to show which National Forest roads and trails are designated for motor vehicle use.
Before you plan a route, check the map’s title, legend, publication or revision information, and coverage area. A map focused on the Black Hills National Forest may not show every road or riding area around Rapid City, Sturgis, or Custer. Conversely, a broad regional map may show a road without clarifying its current motorized-use rules. If you are comparing apps, including onX Offroad, look for the map layer and its source rather than relying on the app name alone.
A useful first question is, “Who manages the place I want to ride?” The Black Hills National Forest, a state recreation area, a city or county, private land, and a designated OHV area can have different access rules. A route drawn across a map does not necessarily mean the public can ride it, and a forest route does not automatically carry the same rules as a trail in a designated riding area.

Read the legend before choosing a route
The legend is the map’s instruction sheet. Find it before looking for a scenic loop. It should explain how the map distinguishes roads from trails, identifies route numbers, indicates motorized access, and marks seasonal or vehicle restrictions. Colors and line styles are not universal: a red line on one map may mean something different on another.
Pay special attention to the difference between a road and a trail. A line that appears continuous on a small phone screen may represent separate segments with different rules. One stretch could be a forest road, another a designated motorized trail, and a third a route that is closed to your machine or to public motorized use. Zoom in and follow the route segment by segment rather than assuming the entire line has one status.
If the legend is hard to read on a phone, open the map at a larger scale or check the corresponding official map. Apps such as onX Offroad can be useful for viewing your position alongside route information, but treat the legend and map source as essential reading—not optional fine print. A GPS dot can show where you are; it does not, by itself, tell you whether the track is legal for your vehicle.
Check route access, width, and seasonal limits
Follow the route designation all the way through
A planned ride often crosses several numbered roads and trails. Make a simple route list before leaving: note each route number, its status, any restrictions, and where it connects to the next segment. This catches a common planning mistake—assuming that a legal road connection makes a nearby trail legal for every machine.
Width restrictions are especially important for UTVs. A trail may be open to a narrower ATV but unsuitable or prohibited for a wider side-by-side. Compare the restriction on the map with the machine’s actual outside tire-to-outside tire width, not just its advertised body width. Mirrors, accessories, or a wider tire setup can make a close fit more complicated. For background on why width matters, see South Dakota Trail Width Limits and How South Dakota Measures Trail Width.
| Map detail | What to check | Why it matters |
|---|---|---|
| Route number | Match the number across each map segment | Nearby lines can have different designations |
| Route type | Check whether it is a road, trail, or other route | Rules may differ by route type |
| Width notation | Compare the limit with your machine’s actual width | A wide UTV may not fit the route’s allowance |
| Seasonal note | Read the dates and any conditions carefully | A route may not be open for your planned trip |
| Closure notice | Check current signs and official notices | A printed or saved map may not reflect a new closure |
| Access point | Confirm a legal place to stage or join the route | A route line does not guarantee parking or public access |
Treat every junction as a decision point. If a trail sign does not match what you expected from your map, stop and reassess rather than continuing in the hope that the route connects back later. That is particularly helpful in a maze of forest roads where two tracks can run close together but have different designations.
A digital map can make those junctions easier to follow. onX Offroad may help you see your location relative to a planned route, while a downloaded map or paper backup can be useful if your phone loses service. Neither replaces posted signs or the applicable official route information.
Check dates, closures, and local notices
A route’s status can depend on the season. Some Black Hills motorized routes have specific open periods, and weather, maintenance, fire danger, or other conditions may affect access. A map that shows a route does not necessarily tell you whether it is open on the day you arrive. Before loading the machine, check current forest notices and any signs at the trailhead or junction.
Seasonal dates deserve a careful read. Do not assume that “summer access” means a route is open throughout the warm months, or that a date printed on one map applies to every trail in the area. The Black Hills have routes with different operating windows; Trails Open May 15 to December 15 and Trails Open August 15 to December 15 illustrate why one blanket season can be misleading.
Weather can also change how a route feels even when it remains open. A wet spring can leave muddy sections, while a storm can bring debris or make a steep road more difficult. A route that looks manageable on a map may be a poor choice for a beginner, a stock machine, or a group that is short on daylight. Check South Dakota Trail Conditions Before You Ride and South Dakota Trail Closures to Check First as part of your planning routine.
Plan a route you can finish comfortably
Choose a sensible starting point and turnaround
A map helps you see connections, but it cannot decide how long your group will take. Plan around the slowest rider, the least experienced driver, fuel range, daylight, and the kind of terrain your machine can handle. A short-looking loop can take longer than expected when the route is rocky, winding, or crowded.
Start by choosing a staging area that is actually suitable for your trip. Confirm that parking and unloading are allowed, then identify a nearby legal route. Around the Black Hills, riders may be planning from towns such as Deadwood, Spearfish, Hill City, or Custer, but distance from town is not the same as distance from a legal trailhead. The map should help you connect the town to an authorized access point without guessing.
Mark a conservative turnaround point before you ride. If the group reaches it with plenty of time and fuel, you can make a considered decision about continuing. If the ride has taken longer than expected, the turnaround prevents a rushed return in fading light.

Use digital tools without relying on a single screen
Offline access matters in the Hills. Cell service can be inconsistent, especially when terrain blocks the signal or you are away from a town. Download the area you need before leaving reliable service, make sure your device can display the route at a useful scale, and carry a charging option suited to the day.
Apps such as onX Offroad can help with route planning and location awareness, but they should be one part of your navigation setup. Save the official map information too, and consider carrying a paper map as a backup. If a phone overheats, runs low on battery, or is damaged in dust or a fall, a second way to orient yourself can turn a stressful pause into a manageable one.
Before starting, tell someone where you plan to ride and when you expect to return. Keep your planned route realistic, and avoid improvising onto an unverified track just because it appears to offer a shortcut. If the route status is unclear, stop at a safe place and check rather than treating a map line as permission.
Use the map alongside permits and on-the-ground signs
Separate route access from permit requirements
A map answers where a route may go; it does not answer every administrative question about riding there. Whether a machine needs a trail permit, plate, or another form of authorization depends on where and how you ride. A road and a motorized trail are not interchangeable for permit purposes, so check the rules that apply to your intended route. The guides Why a Road Needs a Plate or a Permit and Why a Trail Always Needs the Permit explain that distinction.
If your trip includes a designated riding area, confirm its boundaries and requirements separately. A map may show a nearby forest road, trail network, or recreation area without making their rules identical. The same caution applies when a ride crosses from one manager’s land to another: access rules can change at the boundary even if the surface looks continuous.
Build permit checks into trip planning, not into the last-minute scramble at the trailhead. Verify that the permit or registration you need applies to the machine and the specific riding area, and make sure any required decal or documentation is ready before setting out. More detail is available in South Dakota Trail Permits Explained.
Let signs and closures override your planned line
Once you are on the ground, watch for route signs, gates, closure notices, and boundary markers. A sign may clarify a restriction that is easy to miss on a small map, while a temporary closure may not appear on a map downloaded earlier. If a route is signed closed, do not ride around the sign or assume the closure applies only to someone else.
If the map, app, and sign appear to disagree, pause and check the official information for that route. Avoid continuing onto an uncertain segment just to see where it leads. Backtracking is frustrating, but it is far better than entering a closed route, trespassing, or committing the group to terrain beyond its ability.
A reliable map-reading routine is simple: identify the land manager, read the legend, confirm each route segment and machine restriction, check dates and closures, verify permit needs, and then follow posted signs. Doing those checks before the engine starts makes it much easier to enjoy the Black Hills without turning a confusing line on a screen into a riding problem.
