The Peak Forest Canal runs from Dukinfield Junction on the Ashton Canal to the canal's terminus at Bugsworth Basin. It is 14.75 miles (23.7km) long and has 16 locks (all in one flight at Marple). There is one branch, the Whaley Bridge Branch, which is 0.5 miles (0.8Km) long with no locks, and which joins the main line at Bridge 37, just north of Whaley Bridge. The Macclesfield Canal joins the Peak Forest Canal at Marple Junction.
