You shouldn't have any problem using the campgrounds within the park. No electric, dump station in park, water available, restricted hours for generators. Length limit for trailers is 27'. Might be some camping in Packwood, WA.
Beautiful area but can stay cloudy. Lots of hiking & day trips around the mountain.
