Driving and OHV Riding

Whether in a SUV or on a dirt bike, ATV or side-by-side, driving your car or riding an off-highway vehicle (OHV) is a great way to experience Carson National Forest. And when you're out, it's important to help preserve the forest and watersheds for everyone to enjoy and benefit from long into the future.

Before you head out, know before you go about where to ride and how to do so safely and legally.

Where to Ride

Most Forest Service roads on the Carson National Forest are "open to all vehicles," meaning non-highway legal vehicles like OHVs are allowed if they are properly registered. To find such roads, download the motor vehicle use map (MVUMs) for the area you plan to ride and check the legend.

Visual Guide for Reading the MVUM

Vehicles cannot be driven on roads and areas not listed on MVUMs. This protects habitats and watersheds.

Open to Highway Legal Vehicles

While rare on the Carson National Forest, a solid white line with a solid black border indicates that the road is only open to highway legal vehicles.

Seasonal Designation (Closures)

Shading along a road indicates there is a seasonal designation, or closure. Check the Seasonal Designations table for when the road is open.

Always check the Alerts page for out-of-season closures due to unplanned closures and issues (e.g. wildfires, flooding, road construction, etc.).

Dispersed Camping/Big Game Retrieval

Dots on either side of the road indicate vehicles can leave the roadway up to the specified distance (usually 150 or 300 feet) found in the Dispersed Camping/Big Game Retrieval table.

Special Vehicle Designation

Dashed roadway borders indicate only certain vehicles are allowed on the roadway. On the Carson National Forest, this is for motorized trails where only shorter width vehicles are allowed: Motorcyles, ATVs and e-bikes. 

Motorcycles Only

Stay on Designated Roads, Protect Forest Health

Riding off designated roads can damage habitat and watersheds by: 

  • Reducing ground cover: As vehicle use strips away vegetation, top soil erodes and the exposed layer become compacted by further vehicle use and, suprisingly, the force of rain.
  • Compacting soil: Once soil is compacted, it does not effectively soak up the water, a process called infiltration. This creates runoff, sending water immediately downstream instead of being soaked up and slowly released into the watershed over time, which is critical for downstream agricultural uses throughout the growing season.
  • Channelizing flow: Water in meadows should flow over wide areas, but vehicle damage can change the structure of the ground in a way that it channelizes into one spot over time. Like with compaction, this takes away from the slow release of water over time, increases water temperature (which affects fish and other wildlife) and makes the system more prone to flash flooding locally and downstream.

Follow These Laws

Both federal and state laws apply when riding on national forest land. Following them keeps you safe and protects forest and watershed health.
