Take the A44 North out of Oxford. Immediately after the A44/A4260 roundabout turn left onto a private track signed "Loop Farm". Follow the track to the canal. There is parking space in a lay-by on the left hand side of the track. Please don't obstruct either the track or the field-gate that opens onto the lay-by. Cross the canal and turn left on the tow-path. Follow the path southwards on foot for 3/4 km to Duke's Lock. The pond is behind the lock house.
