Would have saved us a good amount of time if they gave us the right combo in the email. The email, said the gate can be rather difficult. It sure was when they gave us the wrong combo. Tried for awhile, then drove around looking for cell service to call the ranger station....none. ended up driving to the ranger station and found someone that could find out the right combo. He said this happens all the time, we have a guy that likes to change it and not tell anyone. Anyhow what a spectacular place! I'd definitely recommend double checking the combo with the office the day you go.
