Go to the Park Center early in the morning and get a ticket for the next available tour. I went when they opened and got a $5 tour at 10am the same morning. Only Balcony House was open. Cliff was closed for renovation and the other was closed indefinitely for stabelization.
You can self guide through most of the park. There are just a few ruins that require purchase of tickets for guides and you can usually buy the tickets when you get there only a few get sold out. The place is so huge that it takes a few days to take see it all. You can easily fill up more than one day with the self guided stuff
Cant self guide into the pueblos themselves. There roads that go by some pueblos, not all. Can see only from distance
If you arrive early, you can easily get in on the guided tours. There are many overlooks, mesa top sites and the museum that can need accessed without guided tours. The visitor center have plenty of information and maps. The staff is also very friendly and helpful
I believe there are some private tour companies outside the park where you can make reservations for your for a fee
If you get there early enough you can still get a ticket but you can't do self guided tours of the ruins.
