A few Statistics
Standedge Tunnel is the longest, highest and deepest canal tunnel in the country. It is 3 miles 406 yards long (5210m), 645 feet above sea level (147m) and 638 feet (145m) below the moorland of Standedge. The tunnel took 17 years to construct.
It was originally 3 miles 135 yds (4950m) long but was extended when the third railway tunnel was built alongside, so that the rail tracks could cross over the canal.
Boat Trips into the Tunnel
Passenger boat trips into the tunnel are run by British Waterways and start from Tunnel End Cottages, next to the tunnel entrance at Marsden. See www.standedge.co.uk for days of operation, times and prices. These trips run into the tunnel for about 500 metres and have a lively commentary provided by a tunnel guide.
The more adventurous may like to consider a trip right through the tunnel. This has to be booked in advance by phoning 01977 554351. It means travelling in the passenger module with the crews of boats being towed through the tunnel (see below). The through journeys only operate on certain days and space is subject to availability. The journey lasts around three hours and you will have to find your own way back to the starting point. (Hourly bus 184 passes through Marsden and Diggle.)
Taking a boat through
Unfortunately, boaters are not allowed to take a boat through under its own power because of ventilation problems. Boats are towed through in short convoys by electric tugs. Crew members from these boats ride through the tunnel in a passenger module. Booking is required (usually at least three days in advance) - phone 01977 554351. See www.standedge.co.uk for latest information.
There are width restrictions on boats passing through Standedge tunnel. Because of difficulties that have occurred previously, boats over 6' 10" beam are not allowed into the tunnel. The width reduces below water level and at around cabin roof height so boats with a vertically sided profile and little tumblehome may be turned away. If in doubt contact BW for advice.
Boats passing through the tunnel are required to have everything cleared from the roof before entering and rubber sheeting is placed over the roof and cabin sides to minimise the risk of paint damage from scraping the tunnel sides.
