Long Description:
Scout Tunnel lies between Stalybridge and Mossley, on the west side of the Pennines, between Locks 11W and 12W. It is 615 feet long (188m) and has a tow path running through it.

It became an English Heritage Grade II listed building in 1986. "It was built between 1794 and 1797, and like most of the canal was surveyed and designed by Benjamin Outram. The parapet wall is slightly curved and made from hammer dressed stone."

This tunnel has a mixture of lined and unlined sections and during the restoration some of the sections were reinforced with steel mesh and rock bolts. This Pennine Waterways website has a series of pictures taken during the canal restoration.

The canal tow path is fully open including through this tunnel. There is a handrail through the tunnel and it is possible to walk through it without a torch, but I recommend that you do use one as it is quite dark in the middle. There is a warning sign warning of low headroom and cyclists should dismount before entering the tunnel.

If you don't want to walk through the tunnel there is a footpath round / over the hill on the western side of the canal.

A recently erected sign states that this is the south west portal, which is surprising as this tunnel entrance is definitely at the northern end.
There are three signs at the entrance as follows.

The Huddersfield Narrow Canal
This canal is one of three that crosses the Pennine Hills and built to provide transport between Huddersfield in Yorkshire and Ashton-Under-Lyne in Lancashire.

As the name suggest it is a narrow canal that although was cheaper to build had less carrying capacity compared to the other two broad canals.

Work started on it in 1794 and partly due to the need to construct the longest canal tunnel in the United Kingdom it was completed 17 years later in 1811.
The canal is only 20 miles long and due to the nature of the terrain has 74 locks even though the summit tunnel reduced the required number of locks. The canal climbs 436 feet from Huddersfield and descends 334 feet to Ashton-Under-Lyne.

In theory having a summit tunnel to reduce the number of locks means that the journey times should be relatively short. However the tunnel does not have a tow path and when it was first opened it was necessary to lead the horses over the moor to the other end of the tunnel. Meanwhile it was necessary to leg the boat through the tunnel. This involved specialist workers who lay on their backs and used their legs with their feet against the tunnel wall to leg the boat through.

Competition from the railways led to the closure of the canal in 1944.

During the 1970s leisure boating in the U.K. had become popular and there were various campaigns to re-open canals that had lain derelict for a number of years.

Work on restoring this canal started in 1981 and the whole canal was finally reopened by 2001. These days the canal is only open to leisure boaters and with the re-opening of other connecting canals it is possible to travel far and wide.

However boats are restricted to maximum width of 6 feet 10 inches and a draught of 3 feet 3 inches which does restrict some boats that are used on the broad canals.
