Sky Island Byway Map


Explore a section of vast biological diversity in just a few short miles, in Arizona’s Sky Island Scenic Byway. The byway begins in the arid desert, surrounded by redrock, spectacular rock formations, and giant saguaro cacti. Stop along several locations to enjoy recreation, or drive straight through to reach Summerhaven – a village located in a beautiful conifer forest. This byway offers a short distance to see amazing views of the islands in the sky (the clouds that are nearly level with the high altitude you reach).
