We recently stayed in the RV area of Beacon Rock. There are 5 sites with hook ups. Sites 1-3 are very close together with 4 & 5 slightly more spread out. What we didn’t know was the train runs directly behind the site multiple times an hour and is loud. The area is very clean and bathrooms were easily accessible with paid shower access. It is a quick walk to the boat dock with gorgeous views. Near the boat dock are two rustic campsites that are slightly tucked back.
We camped in Mid June and were 1 of 3 sites occupied. The campground was extremely clean and quiet. The park host and ranger were helpful and made sure they were available for any questions or needs we had. We stayed on loop A and some of the sites are close together. Be prepared to bring in enough water and the sites have no electricity. For trailer camping I would recommend loop A as it is newest and has 4 drive through spots. Overall, would definitely come back. It was a quick drive to the boat ramp which to the left has access to a small rocky beach area my kids loved exploring.
