The RV dump station is open year-round and is just off the main north park entrance road. A camping limit of 14 days in a 30-day period is enforced. Site #51 is reservable as it is a group site with a max of 4 vehicles and 8 people. All other sites are first come, first serve.
Nice place, very beautiful. The campsites have power (for an extra fee) and water is available at some (but not all) sites. There are two showers, you can’t adjust the heat but the water is warm and the pressure is pretty good. The sites are pretty unlevel, we were hauling a 20 foot trailer behind a 30 foot RV and it was difficult for us to get a level spot
I don't have an RV, but I see plenty at the RV park. There are also boat launches and a " beach" where one can do some swimming (please check for any water advisories).
I fish from the shore and do okay when it comes to catching trout.
