Many states out west allow dispersed camping on select public lands owned by the Bureau of Land management. You need to pick up a map of exactly where you’re allowed to camp (there are no facilities, obviously). You can also rent “cabins” which are buildings from before the building became ghosted (but have been updated). Even if you don’t want to camp you can tour the town and have a surreal afternoon imagining what it’d be like to be a miner back in the day.
