On the Road……Saguaro National Park Loop, Tucson
Saguaro National Park is part of the national park system so bicyclists are required to pay an entry fee just like everyone else. The cost is $5 (with re-entry permitted for seven days with the receipt). Automobiles are charged $10.
As Laura commented in the previous post, a National Park Service annual pass can be purchased for $80, allowing unlimited entry to all parks and national monuments for 12 months.
