The camp ground is $40 a night, it is close to Mammoth lake area.
There are some hot springs around.
Also it is easy drive to Yosemite too.
There is a picnic table and a fire pit at the camp site, it is a flat, you have little to no privacy, yet you have a good view of the mountains. You get something and lose something I guess.
There is a general store, bathroom and shower! You heard it right shower, and it is hot! $2 per token from the general store! Well worthy it after a long day of exploring! So remember to bring a towel with you when you travel or pay another 2 dollar.
