Portal is an unincorporated community in Cochise County, Arizona, United States.

It lies 25 miles (40 km) 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.

[9] Typical of upland Arizona, Portal has a semi-arid climate (Köppen BSk) with warm to hot days followed generally by quite cool nights.

Frequent frosts in winter give way to mild days, whilst most rain comes from summer thunderstorms.
