read some questionable reviews about poor service but on short notice decided to call to make reservations. Phone went to voicemail and said "not to repeat calls as is just slows their service to people who are there" and asked to "leave a message and they will call you back"....2 days now still waiting....glad they didnt answer, went elsewhere instead.

We stayed here due to the fact that our favorite campground was pretty much flooded out due to the snow. We always enjoy our stay at Twin Lakes campground in Mammoth. Mammoth Mountain Campground is basically just a parking lot. The restrooms were terrible. They are a toilet and shower combined. They were filthy and in need of repair. The showere is a push button shower that only shoots water out a little bit at a time. The whole park is dirt very little gravel. It was extremely expensive. We paid $67.00 for a sunday night. We won't be staying here again.
