This isn't for a specific location but for a type of event that takes place in many, mostly remote, areas monthly. If you have any interest in amateur astronomy you might want to consider attending a public star party. They are most often held on the weekend of the first new moon (no moon) in the summer months. Some go on every month while others are held only once a year and everything in between.
Most national parks have monthly star parties in the summer month or at minimum one or two big star parties during the year. The best way to find specific information for a particular park is to search on the park name and "star party".
As cities grow many National Parks are working to preserve their dark skys so people can enjoy the views of the evening sky like our forebears. Here are some links for dark sky locations -

Here are links to some Southern California star parties that are held in or near areas we are familiar with for off roading activities -

A special even occurred this year at the Oregon Star Party (OSP) which is held east of Prineville, Oregon annually in the Ochocho National Forest. This event has been held annually for the last 30 years and the venue happened to be in the path of totality for the Great American Eclipse of 2017 on August 21st. I attended with a group of friends including Jim Mettler, a fellow Pinzgauer owner.
Here is a link to a video which was done on Jim and his astronomical endeavors -

We planned to arrive at the OSP venue on the Wednesday before the eclipse. We knew there was another event which would be using the same 2 lane access road that was expecting 70,000 people. That event was scheduled to start on Thursday so we didn't expect huge traffic backups. There were 8,000 early entry tickets for this other event sold which allows entry on Wednesday. Unfortunately, the logistics for handling even that traffic were not well thought out and apparently detailed inspections were being performed on all vehicles entering the event greatly slowing down the entrance process.
Needless to say we were stuck in traffic for about 7 hours trying to get to our much smaller event.

Fortunately, we had the teardrop trailer so we opened up the back and had a place to make lunch.
Here is another view of the traffic backup -

We finally made it to camp with just about enough daylight to get enough of our gear setup so we'd have places to sleep that night. Normally, there is little or no traffic encountered on the way to this event.
Here is a picture of our camp -

This area is known as the Oregon Scablands. There is dense forest with open rocky areas with little or no vegetation. This is definitely a trade off as you want open skys for astronomical viewing but shade is at a premium during the day. We had to get by with a combination of vehicle awnings, tarps, and camo netting to create a space for cooking and relaxing -
