I’m not exactly sure what town Potholes associates with, but as the crow flies, its about 10 miles south of Moses Lake and about 20ish driving miles off I-90 (via Hwy 17 south and O’Sullivan Dam road… the road goes over the largest earth filled dam in the US. Its pretty cool)
Potholes was another State Park that didn’t let us down. The sites are large and spacious and set so privacy is really available. $29 dollars for full-hookups, $14 for primative camp sites, and I think $10 for an extra vehicle.
Boaters and fishermen are the biggest users of the park. (Although some advised the fishing this month wasn’t the best) Kids will find a swimming area, playground, large grassy area to just run in and thats about all. (Although I understand Moses Lake has a water park, check it out first) There is one hiking trail about 3/4s of a mile long that follows a roaring river. We saw some deer prints in the sand so suspect if you went early, you might meet them. At the end of the trail is a picnic table and a fishing bench.
Just outside the park, there are at least 3 private RV parks, one called O’Sullivans RV Resort I think. While I am not sure about TV, I did see they had WiFi and the sites looked fairly decent. There is another new one going in with an attached golf course and a small one on the lake side that looked fairly full. Wish I had names for you. Mar Don Resort is down the road a bit, and on the lake, but thats all I can tell you about it.
For those who like free/dispursed camping, there is a Department of Natural Resources boat launch area that provides dry camping. They do have pit toilets but thats nothing else. You need to get a permit from anyplace that sells fishing licences.
All and all, we enjoyed our stay at Potholes and I would love to return to check out the Columbia Wildlife Area just south of it.
