Kelmarsh Tunnels (long, dark and a bit spooky but well worth a look)
Kelmarsh railway tunnels are two tunnels 480 Yards long on the old Northampton to Market Harborough railway line which closed in the early 1990’s. One tunnel is open to the public and is part of the Brampton Valley Way walk and cycle path, there is a second pair of tunnels at Oxendon a couple of miles north of Kelmarsh but these are slightly shorter.
