Trail Overview

This route takes you the whole length of the Wyoming Range following the Greys River. Along the way, you'll experience mountain vistas, the beautiful Greys River, wildlife, alpine lakes, and hundreds of places to camp. The trail is not aggressive at all, minus a few water crossings and the occasional mud puddle. The road is graded and well maintained, even turning into a full-size 2-lane road on the northern end. 2WD cars, RVs, camper pullers, and so on will have no issues traveling the main road. The two offshoots on the trail take you to mountain hiking trails and alpine lake hiking trails. Make sure you have fuel and enjoy the beautiful Wyoming Range.

About 18 miles south from Alpine, the road is rough! Pot holes, rocks….the roughest I have ever seen it. Assuming it hasn’t been bladed this year! Usually a nice mountain cruiser, not. 10-20 mph tops. The scenery is always great though.

Started trail from the beginning at Rt 315. Trail seemed in good shape to me. Some rough patches but not too bad. As you go past Smiths Fork there is some mud but no issues. Made it as far as the second Shale Creek loop before turning around to find a camp spot. No issues with snow or ice to that point and travel speed was pretty good most of the time.

Could not be further from a one out of 10. Was going under 10 miles an hour most of the time ended up turning around because there was snow and it was very slow going.

Beautiful trail with great views and flowing river. Few spots with some decent snow on trail still present.

All of the Wyoming Range including Grey's River Rd was very busy with Elk hunting campers.

Trail has some snow drifts 12 -24" deep about 30+ miles in from LaBarge. Very good clearance vehicles on 35s or better may be able to push through. Winch highly advised and plan on a long day if you have IFS, skidplates, and a full size truck.
