|Sonoita Creek along the Railroad Trail|
From Tucson, go 17 miles east on Interstate 10 to the State Route 83 exit 281. Head 24 miles south on SR83 to the SR83/82 junction in Sonoita, turn right (west) on SR 82 and continue 7 miles to Lake Patagonia Road. Turn right and go four miles to the Patagonia Lake State Park gate. Pay the entry fee and proceed to the visitor center to get a free hiking permit for the natural area. Only a limited number of hikers (and horses) are allowed in the natural area at any time. So, call ahead if you're hiking with a group.
