Portal, Arizona

Portal is an unincorporated community in Cochise County, Arizona, United States. It lies 25 mi south-southeast of San Simon and at the mouth of Cave Creek Canyon on the east side of the Chiricahua Mountains. Often called the Yosemite of Arizona, the rock walled canyon is composed of fused volcanic tuff.

The community is a popular location for birding in southeastern Arizona. It is also home to the American Museum of Natural History's Southwest Research Station. The ranch of Sally and Walter R. Spofford was a popular birdwatching destination before closing in 2002. Other notable residents include the writer Nancy Farmer and her husband. The Arizona Sky Village astronomy community is located in Portal because the skies in the area are free of light pollution.
