We camped here for four nights early in the season so there were only a few other campers there. The Manager was exceptional. Very helpful though they take a day off on Mondays and are a little difficult to reach. The store seemed well stocked though we didn't really use it much. The sites were clean, level, with all utilities very functional. The entire area is treed and right along the Snake River below the Lower Granite Dam. There is a small beach area, a marina, as well as very nice day use facilities. There are paved paths along the river going both upriver and down. We hiked both directions. Upriver takes you right up to the dam. There is a nice visitor center on the other side of the river at the dam. It's a little complicated to cross the dam, because you have to be escorted. Don't try to take a big camper across the dam because the route is a bit circuitous. The restroom/shower facilities were old, but clean and in good repair. Laundry facilities were minimal and old. Overall a very enjoyable camping experience for us. We camped here in a Fifth Wheel.
This is a very nice campground which is well shaded, and is part of a marina on the banks of the Snake River not far from Pullman, WA. We stayed two nights in the off season, and still the park was pretty much full. During the summer this place could get real hot, and windy. There is only one road in, and it can be very steep and windy. That's the bad part. The good part is that this is a really nice place to stay. Most of those staying are probably fishing the Snake River. There are "Premium sites", regular sites, and sites with partial hookups. We used this as a base while attending a football game at Washington State University. Warning...the students at WSU know about this place, and in April and May will come here to hit the beach and party. They won't bother anyone in the campground. We camped here in a Fifth Wheel.
I spent a few days here, and it wasn't bad. It wasn't crowded in the middle of summer, so felt spacious. It's all nice green lawn, which is continuously watered. A wall of tall trees lines the sites along the fence, and help protect against the heat and wind, although other sites are in the open. My site was level, and the "unofficial" host helpful. The showers were clean, and offered lots of hot water- just remember to allow about 3 minutes for it to warm up. The showers are not in the rest room closest to the spaces, but behind another building so you may need to ask someone for directions. Although the park is not on the highway side of the fairgrounds, you will have some (but bearable) truck noise. The office is not open regular hours, but there is a drop box by the entrance. We camped here in a Travel Trailer.
The fairgrounds has a large flat grassy area that they put electric and water in. Each post services 4 RV's, normal for fairgrounds. The campground is fenced in and very quiet. We barely received Verizon Broadband. The fairgrounds are 5 miles west of Colfax, WA., on WA Highway 26 and Endicott Rd. The campground is on the north end of the complex. There is a dump available for $5 though we didn't use it. We camped here in a Motorhome.
