South Dakota ATV Trails Near Custer
Finding ATV trails near Custer can be confusing: a road that looks rideable on a phone map may be closed to motorized use, while a nearby route may have seasonal or width restrictions. This guide explains how to find legal riding near Custer, choose routes that fit your machine, sort out permits and access, and plan around the Black Hills’ changing conditions.
How to find legal ATV trails near Custer
Start with official route maps, not just a pin on your phone
Custer sits close to the Black Hills National Forest, but that doesn’t mean every forest road, two-track, or dirt path is open to ATVs and UTVs. Access depends on the route’s designated use, the type and width of your machine, and any closures or seasonal rules. A line that appears on a general road map—or that someone mentions in a riding group—doesn’t confirm that motorized travel is allowed.
Before you unload near Custer, check the Forest Service’s Motor Vehicle Use Map, commonly called the MVUM, along with current forest notices. These resources help you identify routes designated for motor vehicle use and any limits that apply. For help understanding what to check, see [South Dakota Trail Maps and MVUMs] and [South Dakota Trail Closures to Check First].
Mapping apps can be handy for planning. For example, onX Offroad can help you explore route options and keep track of your location, but use it as a planning aid rather than a substitute for official route designations. Compare what you see in the app with the applicable MVUM and posted signs before you ride. A route shown on a screen is not automatically an open trail.
Understand the difference between trails and roads
“Trail riding near Custer” can mean several different things: a designated motorized trail, an open forest road, a legal route between riding areas, or a private road where permission is required. Those categories don’t always have the same rules. A route that permits highway-legal vehicles, for instance, may not be open to every off-highway machine.
Pay attention to signs at intersections and trail entrances. A closure sign, a route marker, or a restriction on vehicle width can change what you may ride even if the route continues on the map. If you reach a gate or a sign that conflicts with your planned route, don’t assume the road becomes legal farther ahead. Turn around and confirm the route before continuing.
A practical starting point is [Best Places to Ride an ATV in South Dakota], then narrow your options using the official maps for the area you plan to visit. If you’re still unsure whether a particular road or trail is open, ask the relevant ranger district before driving out with your machine.
Choose a route that fits your machine and your plans
Check width limits before bringing a UTV
A UTV can be comfortable for a longer day, but its width may rule out some routes. In the Black Hills, motorized trails can have width limits, and a machine that is only a little wider than the allowed maximum may not be legal on a route. Don’t estimate from the driver’s seat or assume the machine’s advertised width tells the whole story.
Measure from the outside of one tire to the outside of the opposite tire, following the method required for the route or area. Include any accessories that affect the machine’s total width if the applicable rules call for them. Then compare your measurement with the posted or mapped restriction. For more guidance, see [South Dakota Trails for a Wide Machine] and [Measuring Outside Tire to Outside Tire].
| What you’re riding | What to check before choosing a route |
|---|---|
| ATV or quad | Route designation, permit requirements, closures, and any machine restrictions |
| Side-by-side or UTV | All of the above, plus the machine’s measured width |
| Street-legal ATV or UTV | Whether the route allows the vehicle and whether separate trail rules still apply |
| Rental machine | The outfitter’s approved riding area, permit arrangements, and machine restrictions |
If you’re renting near Custer, ask the outfitter which areas and routes your specific rental may use. Don’t rely on a general answer like “you can ride in the Hills.” Ask whether the machine is allowed on the route you’re considering, whether a trail permit is included or required, and how the outfitter wants you to handle closures. The machine’s size and the rental company’s rules can both affect your options.
Match the ride to your group’s comfort level
The closest legal route isn’t necessarily the best route for every rider. A newer rider may be more comfortable on a broad, manageable road than on a narrow trail with loose rock, tight turns, or a steep climb. In the Black Hills, changing elevation and surface conditions can make an easy-looking route feel more demanding than expected.
Before setting out, agree on a realistic turnaround point and make sure everyone in the group is comfortable with the terrain. Keep the pace slow enough for riders to see loose gravel, washouts, and approaching traffic. If one person is uneasy, it’s better to shorten the ride than to pressure them into continuing on terrain they don’t feel ready to handle.
For a broader sense of what riding options suit different experience levels, see [South Dakota Trails for Beginners] and [South Dakota Trail Difficulty Ratings]. Use those descriptions alongside the official route information rather than treating a difficulty label as a guarantee. Weather, traffic, and the condition of the trail can change what a route feels like on a particular day.
Permits, nearby boundaries, and common planning mistakes
Check trail permit requirements separately from road access
A common point of confusion is assuming that a license plate, registration, or permission to use a road automatically covers riding a designated motorized trail. Trail permits and road-use requirements can be separate. Confirm what applies to your machine and the exact area you plan to ride before you leave home.
Start with [South Dakota's Motorized Trail Permit] and [Do You Need a Permit on a Black Hills Trail?]. Check where permits are required, whether one is needed for each machine, and how it must be displayed. If you’re visiting from outside South Dakota, don’t assume your home-state registration replaces a local trail permit. Verify the rules for your particular route and vehicle.
If you use onX Offroad to build a route, make the permit check part of that planning process rather than a last-minute task. Keep the permit information accessible, and look at the official map and notices again before unloading. That extra check can save you from arriving at a trailhead only to discover that your machine is not authorized for the route or that the area is closed.
Treat Custer State Park and the Mickelson Trail as separate destinations
Custer State Park is a major attraction near town, but its roads and recreation areas should not be treated as an extension of the Black Hills National Forest motorized trail system. Park access rules and road rules are different from forest trail rules. A machine that can be operated on one route may not be allowed on a park road or recreation area in the way you expect. Check [South Dakota Rules for Riding Custer State Park] before planning a ride that involves the park.
The George S. Mickelson Trail is another nearby feature that can cause confusion because it is a popular trail corridor in the Black Hills. It is not an ATV route. Review [Why South Dakota's Mickelson Trail Bans Machines] if you’re planning a trip around the trail and nearby towns. Keep your ride on routes designated for motorized use, and don’t assume that a multi-use recreation corridor permits off-road vehicles.
Private land creates a separate boundary issue. A track that appears to connect two public routes may cross a ranch or other private property. Do not use it unless you have permission from the landowner. Respecting those boundaries matters in a working landscape where livestock, gates, and ranch traffic are part of everyday life.
Plan a safer ride from Custer
Check conditions and closures the day you go
A route that was open the last time you visited may be closed or difficult to ride now. Rain can leave mud, ruts, and slick sections; dry weather can mean loose dust and reduced visibility. Fire restrictions, maintenance, weather, or resource protection can also affect access. Make a final check of current forest notices and [South Dakota Trail Conditions Before You Ride] before loading the machines.
Keep your plan flexible. If a route is closed, don’t try to bypass the closure by taking an unmarked spur or crossing land that isn’t open to you. Choose another legal route or make the day shorter. That may feel disappointing after a long drive, but riding around a closure can create safety problems and damage access for other riders.
When using onX Offroad or another navigation app, download or save the information you need before heading into areas with weak cell service. Still carry or have access to the official map for the area. A phone battery can run low, a signal can disappear, and a map layer can be misunderstood; having a backup makes it easier to retrace your route or find a legal way back.
Build a simple pre-ride checklist
The morning of a ride is a poor time to discover that your vehicle is too wide for your planned trail, your permit is missing, or the route is closed. A short checklist helps catch these problems before you leave Custer or your lodging.
- Confirm that each planned route is open to motorized use.
- Check width limits and any other machine restrictions.
- Confirm the permit and road-use requirements for your vehicle.
- Review weather, closures, and surface conditions.
- Save maps for offline use and carry an official route reference.
- Tell someone where you plan to ride and when you expect to return.
- Bring water, basic tools, and clothing suitable for changing conditions.
For a group ride, make sure everyone understands the route and agrees on a meeting point if the group gets separated. Ride at a pace that leaves room to react to dust, loose rock, wildlife, and other trail users. If visibility drops or conditions become uncomfortable, slow down or turn back.
The best ATV trails near Custer are the ones that are open, legal for your machine, and a good fit for the people riding that day. Verify the route before you go, pay attention to signs and boundaries, and keep a second option in mind in case conditions change. That little bit of planning can make the difference between spending the day riding and spending it sorting out an avoidable access problem.
