Tucson, United States Welcome to the historic Hacienda del Sol Guest Ranch Resort. We invite you to enter the un-hurried world of our tranquil hideaway. The Hacienda, or ?Inn of the Sun,? has been lovingly and authentically restored. The Hacienda is set on thirty-four peaceful, secluded acres of natural desert landscape, which frame the resort?s private casitas, guestrooms and historic adobe buildings. Providing every guest with ?the Best Stay in Tucson,? is our mission, and on your next visit to the Old Pueblo, make it yours as well.
