Arrowrock off season
Super great spot that is close to town - pro's and con's are already covered and i agree - especially packing out more than you pack in as trash spoils the appeal. Driving a large bed camper isn't so bad but is slower for sure and the narrow spots can be sketchy with multi-vehicle with trailers meeting there. I like the shoulder seasons best - wish i had a boat to add additional fun. Your results might vary but I've had nothing but fun in the area.
