The Erewash Canal starts on the River Trent at Trentlock, just a few miles west of Nottingham, and goes north through Long Eaton in Derbyshire. It then runs roughly parallel to the River Erewash and past Sandiacre and Ilkeston. It then crosses the small River Erewash on a small aquaduct near the former coal mining area of Eastwood. The canal finally ends at the Great Northern Basin near to Langley Mill, where it joins the Nottingham and the Cromford Canal, both of which are currently abandoned at this point. The total distance is nearly 12 miles and there are 15 full-length wide locks.
