Trail Overview

This designated Wyoming Scenic Backway makes a large semi-loop through the vastness of north-central Wyoming. It's a remarkable drive that crosses more than a hundred miles while catching the southern tail of the Bighorn Mountains. The lower elevations pass through oil patches before climbing higher beside massive red scarps and buttes. Higher still, the road reaches intermittent forests and sweeping open uplands near a couple of lightly-visited campgrounds. On the northern side of the loop, watch for a sign marking Roughlock Hill; this is where pioneers would lock their wheels and slide their wagons down the steep slope. Be sure to fill your tank before tackling this drive and don't hesitate to turn back if road conditions are not favorable.

Difficulty

Nearly a third of this drive is paved and the remaining unpaved portion is in relatively good condition. The rougher and more primitive upper portion, which follows the Big Horn Mountain Road (CR 109/ CR 110), can be bypassed if needed. This higher road includes steeper grades, a rocky road surface, and a few shallow fords. Snowdrifts, even into late spring, and wet summertime weather can also make travel difficult. This road is not recommended in the off season.

History

Aside from the wagon trains that passed through this area generations ago, a number of historical stock driveways also crisscross this rough country. Today, the land is mostly used for recreation, sheepherding, ranching, and oil production.

The middle section of the trail is what I would call the stair master, stair stepper which will wear you out if you have stiff suspension. The layers of rock within the formation are exactly like driving up and down steps. Finding the right speed to have your suspension take up some of the rough surface is key. Be prepared for potential greasy like mud if it has rained. There are a couple of water crossings that are less than a foot deep but might be deeper in spring runoff. I wouldn't recommend driving anything that has street tires with shallow tread or thin sidewall/ low profile type tires due to possible sidewall bruising or cuts with sharp edges on rocks. Some AWD vehicles might be ok with a good driver on street tires or vehicles with modifications but otherwise might encounter damage. Old tire treads along the road throughout the loop indicate street tires and trailer tires will fail first. Starting on the Arminto side has more to see.

Easy dirt road but for the portion up the mountain where there are two campgrounds and some amazing views. The road itself isnt bad at all, but there are some good grades that will make a weak vehicle suffer. One creek crossing that was a good foot or more deep.. Dont miss out on the view of Red Wall as you pass by

Cows and cow pies. A few water crossings on the back country byway. Pleasurable ride.
