As you traverse the route, expect classic desert scenery, with saguaro cacti dotting the landscape and expansive views of the Estrella and White Tank Mountains.

Planning your visit

Estrella Mountain Regional Park is a large preserve, and while this loop starts from the Fee Booth, be aware of the park's multi-use trail system. Given the challenging terrain for touring bikes, ensure your equipment is appropriate for rocky, loose surfaces and elevation changes. The park offers facilities like a nature center, and it's always wise to carry plenty of water when cycling in the Arizona desert, especially during warmer months.
