Camping near Mammoth Lakes?
My wife and I are planning a group family camping trip for the begining of June. We are thinking about trying the Mammoth, CA area. Any body have any suggestions for campgrounds out that way? Preferably w/flushing toilets, for my wifes sake.
Thanks everybody!
You might try June lake loop there are a few campgrounds there. And you would be walking distance from the lakes if you wanted to fish. There is a lot to see in the Sierras. Lots of history, talk to the rangers up their they will give you good info. Keep your camp clean and your ice chest in the Bear box and you wont have Bear trouble.
