Trail Overview

This exciting and beautiful route runs deep into the Absaroka Range to reach Kirwin, a deserted Wyoming ghost town. Before you get there, you'll pass Lower Sunshine Reservoir, verdant pastures, a Forest Service guard station, and a pair of public campgrounds. Within the Shoshone National Forest, the road follows Wood River as it winds below lofty summits such as Francs Peak (13,153 feet). After the last campground, the road fords Wood River, which often flows at least a foot deep, even late in the season. This is the first of several crossings. Mining ruins can be spotted on the hillsides as the road nears the Kirwin site. There is a parking lot with informational signs, a trailhead, and a vault toilet at the end of the road. From here, you can explore the old townsite on foot. All vehicles must be highway legal.

Difficulty

The first 20 miles of this route are easy and can be made in any vehicle. However, the last 8 miles have several river crossings and cover a rockier path. This last stretch should only be attempted from July through September with a high clearance, 4x4 vehicle. It's typically an easy drive when water levels are low, but use caution if rivers are running high.

History

By 1906, more than 200 people lived in this gold-mining town before they left following a massive avalanche.

We went to second water crossing, the long one, It was completely frozen over . We were unable to gauge the depth. Being stuck in flowing ice water,, Umm no. We turned around.

Took the Power Wagon for this trip. Aired down for comfort but never came close to needing anything but 2wd. Water was very low. This is an extremely easy trail and would be a great learner trail for a teenager learning to offroad. We were followed up by a couple in their 60's in a completely stock Nissan Rogue on OEM tires if that tells you anything. Super fun afternoon.

Start of the trail was washboard on Wood River Rd. Past the second campground things tighten up and get a bit more fun. The reason this was not a green was simply water depth was over a foot but closer to 1.5ft. Also, active livestock on the road towards the very end. All in all good fun

Normally when a trails difficulty is severely overrated I says it’s so easy a Subaru could do it. Today however, I witnessed a front wheel drive Kia navigate what was supposed to be a Category 5 difficulty trail with street tires and they had no problem. This trail should not be rated higher than a 2.
