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.
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.
