Built between 1830 and 1870, Rancho De La Osa is one of the last great Spanish haciendas still standing in America. The history of the ranch has been lovingly preserved in the beautiful buildings that rest in the rolling grasslands of the high Sonoran Desert. The 18 guest rooms are uniquely and vibrantly furnished with Mexican antiques. All rooms are ground level with separate entrances and private bathrooms, and most rooms have wood-burning fireplaces. All guest rooms are a short walk to the pool, hot tub, hacienda, hiking trails and corrals.
