If you think that the Arizona Canal is the only canal with a great bike/jogging path, you're missing out. The Grand Canal, the oldest remaining pioneer canal on the north side of the Salt River, runs 21 miles from 75th Avenue and Camelback Road all the way to Papago Park. You can take your bike or just enjoy a leisurely walk along the path which, thanks to the city of Phoenix and the nearby residential developments, is landscaped in some areas (especially near where it crosses Central Avenue). The path is paved in most areas, though in some areas it's a hard-packed dirt path. This is also a great place to go bird watching, as many birds, especially wading ones, are frequently seen along the route.
