It is worth the effort to leave the interstate and visit this gem of a park. The campground is part of the Rock Creek Station State Historical Park, which preserves and interprets the role this "station" played on the Oregon Trail and the Pony Express. The ranger was very accomdating and opened the historic buildings for us early. The campground is connected by trail to the visitor center and station buildings. The campground itself was a shady oasis on the extremely hot day we were there. The paved pads were level, and the restrooms were immaculate. The host was welcoming too! A nice touch were the gorgeous flowers outside the shower house, and the handmade birdhouses at many of the sites. We'll be back to explore more of the trails. We camped here in a Motorhome.
