empire ranch headquartersDescription 
The historic Empire Ranch Headquarters is magnificently situated in the high Sonoran Desert and rolling grasslands of Arizona, surrounded by the Mustang, Whetstone, Empire, and Santa Rita mountain ranges. It includes a 22-room adobe and wood-frame building which dates to 1870 and is listed in the National Register of Historic Places. The ranch headquarters sits at the heart of the 42,000-acre Las Cienegas National Conservation Area, on public lands acquired and administered since 1988 by the BLM.

The BLM has worked closely with the Empire Ranch Foundation to preserve the house and other structures, host educational programs, and provide literature to tell the story of this special place.

The Las Cienegas NCA can be enjoyed year-round since each season provides opportunities to enjoy the unique features of the NCA’s landscape, however fall and spring provide the most comfortable temperatures.
The ranch is located approximately 50 miles south of Tucson in the Las Cienegas National Conservation Area.
From Tucson, go east on I-10. Take Exit 281 toward Sonoita and drive south on State Road 83 for approximately 17 miles. Turn left (east) into the entrance of the NCA near mile post 40. Follow the dirt road three miles to the Empire Ranch Headquarters.
