Quick, easy, and inexpensive stay right off the interstate. Water and electric on site and easy pull through parking spots. Clean bathroom and shower. Not very quiet considering the interstate is right next to it.
Growing up in southwest Kansas it is difficult to take a quick weekend trip anywhere close. Horsethief sure changed that. A quick hour drive from Garden City and you can be on the water or setting up your camper. Spots can fill up quick so be sure you call ahead. However, there are plenty of primitive spots that have room most weekends.
Awesome campground next to the river. Nice and quiet. The road coming in is pretty rough with washboards but I will happily come back again.
