So you want to do some hiking and camping outside of camp grounds in the National Parks. You should check if you need to "Pack It Out" as this is common.
Inyo National Forest website is the best out there that explains in detail what you need to do:

To the point information like this can be hard to find especially about going to the toilet in the wild, so I advise you to read it. Some tips that you just don't get in guide books or from the nps.com
