In reply to SWalls:
If its hot then Holcomb Valley (above Big Bear Lake), it faces south so is warmer than its altitude would suggest. Free campoing at the crag.
Alabama Hills have more climbing than a single trip would allow to complete (note only routes over 100ft/30m have lengths in the guide). Camping is free.
But the secret Mamouth crag is Area 13, John Bachar's secret area. Unless you have a full on 4x4 do not try to drive to the crag, there was (in 2019) a 2ft step on the access road. Examine the local map and there is a flat gravel road due west from which a simple walk/slide gets to the crag, climbing back up the pumice slopes is harder!
The other good crag is New Jack City, free camping, pit toilets, no water. walk-ins from 1 minute to 20 minutes.
