In the spring, the stretches of Piru Creek from Pyramid Lake to Lake Piru and from Santa Felicia Dam to the mouth are actually possible to raft and kayak. The first stretch has rapids up to Class IV and includes the challenging section known as Falls Gorge, while the calmer second reach has Class I-II rapids only. Controlled water releases from the two dams provide some regulation of the flow although an effort is made to simulate natural discharges. As a result, the section is usually only runnable after rainfall. From downstream of Pyramid Dam to the Los Angeles-Ventura County line, Piru Creek in various sections is designated a National Wild and Scenic River.
