70¾ milesThe Grand Union Canal is the backbone of this route with its towpath
taking you past locks, canal-side pubs, over the Blisworth Tunnel and into bustling Stoke Bruerne with its canal museum and other attractions.
The River Nene is carefully managed by the Wildlife Trust offering a haven for wildlife as well as a natural barrier to Northampton's urban sprawl. The trail passes through Salcey Forest - popular with families, Castle Ashby with its gardens and rural shopping village and the medieval village at Old Wolverton. The old Roman town of Lactodorum, now known at Towcester, offers much to see including the racecourse.
Blisworth Tunnel (Blisworth end)
Completed over 200 years ago, at 3076 yards long it is the longest self-navigable canal tunnel in regular use on Britain's inland waterways. It is wide enough to allow two narrowboats to pass.
