About

Discover the enchanting beauty of Fossil Creek, a designated Wild and Scenic River that winds through a dramatic Arizona canyon. This unique destination, once the site of pioneering hydroelectric power, now thrives as a testament to successful river restoration, captivating visitors with its vibrant turquoise waters, lush riparian habitats, and remarkable travertine formations. It's a cherished escape where history and nature converge in a spectacular display, offering a refreshing contrast to the arid desert landscape.

The area boasts crystal-clear, 70-degree Fahrenheit waters flowing from natural springs, creating picturesque swimming holes and stunning travertine waterfalls, including the popular Dixon Lewis Waterfall and the secluded "Toilet Bowl" fall. While the historic Irving Power Plant has been largely removed, remnants of the early 20th-century Childs Power Plant and its intricate flume system stand as poignant reminders of engineering marvel. The revitalized creek supports a vibrant ecosystem, home to diverse native fish like the endangered Gila topminnow, and a haven for birdwatchers seeking species such as the common black hawk and Bell's vireo, alongside river otters and beavers.

Visiting Fossil Creek offers an immersive experience, inviting you to swim, hike, and explore a landscape shaped by both human ingenuity and natural wonder. It’s an ideal spot for photographers capturing the striking colors and geological formations, and for anyone seeking a peaceful retreat into Arizona's surprising backcountry. The journey through its rugged terrain is rewarded with unparalleled natural splendor, a living example of conservation success that leaves a lasting impression. Eager to name that creature?

Good to know before you go

Reserve Permits Early

During the permit season (April 1 - October 1), book your $6 vehicle permit through Recreation.gov as soon as they become available, as they often sell out weeks in advance.

Pack Sufficient Supplies

Bring plenty of water (at least 1 gallon per person, per day), food, and sun protection, as there is no potable water or services in the canyon, and summer temperatures are extreme.

Use a High-Clearance Vehicle

The access roads, particularly Forest Road 708, are unpaved, rough, and winding, making a high-clearance vehicle highly recommended.

Dress Appropriately

Wear sturdy hiking shoes for trails and consider water shoes for navigating the rocky creek bottom and slippery travertine.

Download Information Offline

There is no cell service in the canyon, so print your permit, maps, and any essential information before you go.

Practice Leave No Trace

Pack out all trash, as there are no trash cans. Glass containers and campfires are strictly prohibited to protect this sensitive ecosystem.

Fossil Creek is fed by mineral-rich springs that create extensive travertine deposits, forming unique rock formations and waterfalls, and giving the water its distinctive turquoise color and constant 70°F temperature. It is one of only two Wild and Scenic Rivers in Arizona.
While the Childs-Irving Hydroelectric Facilities were decommissioned and much of the infrastructure (including the dam and Irving Power Plant) was removed by 2008 to restore Fossil Creek, remnants of the Childs Power Plant and some flume footings can still be observed. The area primarily showcases the restored natural beauty and ecological success of Fossil Creek.
