The best method of finding places to camp that I’ve found is to use an app called iOverlander.
As you can see from the below image I use a few different apps when I’m outdoorsing.

My go-to app is iOverlander though, it shows you wild camping sites such as BLM land. You can actually view locations via their website without installing the app.

Check out how I filter on the app, the wild camping filter shows BLM and free camping locations. Wild camping, where the water is, where can I shower and the tourist attractions along the way are my priority concerns.

Let me know if you have any questions by contacting me, I’m always happy to help.
