ABOUT RANCHO DE LA OSA

Welcome to Arizona’s most historic ranch…

Rancho de la Osa offers a unique convergence of Native American, Spanish, Mexican, ranching, political and Hollywood history. The ranch’s original adobe buildings still stand with the earliest built in 1722 by Jesuit missionaries who traveled with Father Kino. La Osa operated as a cattle ranch through the 1800s, during which the Spanish-style hacienda was constructed. The ranch first welcomed dudes in the 1920s and in its years as a dude ranch, played host to prominent guests including politicians, Hollywood actors and authors.

Today, by building upon the traditions of its past, Rancho de la Osa offers an authentic western experience to its dude ranch guests in the borderlands of Southern Arizona. Our ranch offers an unparalleled guest ranch experience with exceptional food and drink; unmatched hospitality from our staff; and different activities for you and your family to enjoy.
