4 Wheel drive
Powder Horn Area Campground is part of Merritt Reservoir State Recreation Area near Valentine, NE.
I traveled this area in September, when I left Kentucky it was in the 80’s, my first night in the Valentine area it got down to 41 and didn’t go above 55 for the entire time I was there. That being said pack a variety of clothes because the locals said it can be in the 70’s one day and snow the next this time of year ;)
Powder Horn is on the far side of the Merritt dam close to the entrance of the Samuel R. McKelvie National Forest. I’m from Kentucky and there is no forest in McKelvie, just a lot of prairie grass, sand and hills. Think of the desert with long grass on top. Pretty in a stark sense.
Powder Horn is a primitive campground set up with lots of trails off the main road in, a 4 wheel drive might be needed for some of the areas. There is a pit toilet and a boatramp in the main area otherwise you’ve a choice of locations to set up base camp. Merritt is all about fishing, there is a fish cleaning pavilion in the main camp area on the other side of the dam. I did not see an employee my entire time in the area, bring cash to pay for your site. Valentine was about 30 minutes away with fuel, food and some entertainment.
