The Navajo National Monument website notes that Betatakin can only be visited on a ranger-guided tour. It states that groups leave daily between May 27 and September 3, and cliff dwellings are closed from October through April. We will pass through the area May 13–14. Is it possible to visit Betatakin during this period?
You will have to call and find out.
