Today we are off to Rancho Santa Inez in the community of Catavina. This will take us through El Rosario where the highway ended prior to construction of Mex 1 in 1973. This campground is located in the heart of the Catavina Boulder Fields and its impressive and unique Sonoran Desert vegetation includes Cirios cactus. Believe it or not these giant boulders of granite were created in place by weather and freezing temperatures. You will have an opportunity to walk or hike in the desert and see close up walk this very unique desert has to offer. This is indeed a photographers paradise and a fabulous spot for star gazing too! Make sure your furnace is working as the campground is located at approximately 1800′.
