Trail Overview

Greys River Road is a well-graded dirt road that can be done by most vehicles. The area is amazing, and just the main road itself is worth a visit. The best way to experience this area is to camp up the road close to alpine and ride OHVs up the road and explore the side trails as you go. Be aware that this road can be very dusty. It is definitely best to give each other space and just enjoy the scenery. There is a 35 MPH speed limit on the main road and is enforced. You must purchase an out-of-state Wyoming sticker for your ATV. There is quite a bit to do, and a lot of good camping in the area.

This trail is NOT a 5 … it’s barely a 1

This is NOT a 5. It is a gravel road that becomes narrow at some spots but this is a 1 not a 5.

This is more of a hard pack road with horse trailer ruts than a “trail”. If this is a “5” then a 1-2 must be as smooth as I-80. Beginners would have no issue.

Really OnX, 5 out of 10 difficulty? This road was smooth, long, dusty and every local with 5th wheel camper was here. Boring trail and every campsite was full with what looked like full timers. Even the side trails were kind of boring. The dust is unbearable and the traffic is like a major highway.

A well graded gravel road to Greys River Road FR 10138. Occasional washboarding or small potholes.
