A:Upper Salt River Canyon, Arizona
Spring is really the only time to paddle the 50 miles of the Upper Salt River that run through the Sonoran Desert in Arizona, when torrents of snowmelt crank the rapids up to Class III and IV. The route passes through the lush Salt River Canyon, carved 2,000 feet deep into the White Mountains. Pack warm clothes for this trip, because nights can get chilly.
Salt River Rafting runs trips ranging from one to five days, starting at $109 per person.
