The Alt runs from Hag Plantation in Huyton at 125 ft (38 m), through Croxteth Park, roughly follows the M57 motorway south of Kirkby, then flows north of Aintree and south of Maghull. Historically in Lancashire, it then runs south of Formby and empties into the Irish Sea, near the edge of the River Mersey estuary at Hightown.
