We just drove through there on our way to Steamboat Rock SP on Banks Lake,,, which was wonderful.
We needed to pick up a few things at a grocery store before we arrived, and made the mistake of stopping at Soap Lake... we thought that we were in the bar scene for Star Wars, and we left (ran) without buying anything, we then stopped at Coulee City and had a great experience at their grocery store.
We have camped at Sun Lakes SP for more than 30 years, and have really enjoyed our stays there, but we enjoy Banks Lake SP more now. We are not familiar with that specific site.
