This is an awesome campsite! You camp on to of an enormous canyon that you can hike down to the river if you're up for a challenging hike! I followed my GPS and it took me on crazy roads into the middle of nowhere near private property signs, so don't follow the GPS, follow signs and stay on that main road it leads to! It really feels like you are in the middle of nowhere. The views are so beautiful I definitely reccomend. There is a latrine and fire rings/grills at each site!
This primitive campsite is located along the middle fork of the Powder River west of Kaycee, Wyoming. I would suggest an AWD or 4WD vehicle to reach the site. This area of Wyoming is called Hole-In-The-Wall country, and Butch Cassidy and the Wild Bunch used to hide out in the vicinity. There are also some very nice pictographs nearby.
The campsite is free with a vault toilet and no other amenities -- no potable water, no wood, and no trash pick up. Haul out what you haul in. It can get very hot and windy here in the summer. So much so that I cut a two night trip short by one night. You have access to the middle fork of the Powder River, but it's about 800 feet below you as the campsite is on a canyon bluff.
