Ellensburg KOA might be the only game in town, but it’s a great campground for the overnighter or the fort-nighter. It’s located right on the Yakima River, and it has easy access to I-90.
Sites are full service but some are too far from WIFI to reach so ask to make sure. They have bike rentals, a video arcade, a little store, snack bar and lots of extras. Also they have a nice area for tents.While we didn’t have reservations, would highly recommend getting them for great site selection.
