Put the Desert Queen Ranch, aka Keys Ranch, on your list of things to see on your next visit to Joshua Tree National Park. It's a glimpse back in time to a hardier era, and into the mind of one of the area's most notable early-day settlers, Bill Keys. The Ranch is only accessible via Ranger-guided tours, and generally only on the weekends. Check in at any of the visitor centers located at the park entrances to make a reservation.
