Pima County Parks and Recreation: Big Wash Nature Trek

Join a naturalist-guided walk along Big Wash in Oro Valley, on an easy- to moderate-level trail.

In addition to great views of the Santa Catalina Mountains, this area is designated an important wildlife corridor, so we’ll keep an eye out for native birds such as Gila woodpeckers and cactus wrens, and other desert wildlife Trekking poles encouraged, and sure-footedness is a must.
