great campground with a great staff
I stayed here for 3 nights while section hiking the Pacific crest trail & everyone I came into contact that worked at reds meadoow was extremely helpful and polite. there's a restaurant (diner food) that's open 8am - 6pm (check hours) & also a general store that sells all your camping needs. there was also a free shuttle from Reds Meadows to mammoth mountain ski lodge where you can catch a bus into Mammoth lakes.
campground has multiple concrete buildings with toilets & running water as well as bear boxes & fire pits. also a steam depending on time of season.
