Blisworth Tunnel

Blisworth Tunnel, on the Grand Union Canal, is:

3,075 yards (2,811 meters) long
the longest wide, freely navigable tunnel in Europe (it's wide enough for two narrowboats to pass in opposite directions)
the third-longest navigable canal tunnel in the UK, after Standedge and Dudley Tunnels
the ninth-longest canal tunnel in the world
about 143 feet (43m) below ground level
roughly 18 miles (29km) from the northern end of the Grand Junction Canal at Braunston

And importantly, it's also just a short walk along the towpath at the Stoke Bruerne end from the Canal Museum, which holds great stories and memorabelia from the tunnel. Combine the two places to visit for a great day out.
