Charleston is always the go-to during summer, as it’s 20 degrees cooler than it’s surrounding area. Dispersed camping is great - no utilities of course, but very quiet, not many other campers, and a great place for stargazing. We even saw a mule walking around in the morning. Forgot my trekking poles to set up as tent poles, but luckily, Charleston is one of the few places in NV with literal trees. Can be around a 20 min drive to whatever trails you’re interested in.
