Our popular tunnel boat trips depart from the London Canal Museum near King's Cross station and take you in a small group through London's longest canal tunnel. A guide travels with you to provide a commentary on the history of the tunnel and canal, and tea and coffee will be served during the trip. All tickets include a museum visit so make the most of your inclusive ticket and come at least an hour before the trip or plan to stay on after if boating in the morning. The tunnel is about 3/4 mile in length and has been in use since 1820. It is essential to book online in advance.
