Tewitfield Marina sits at the northernmost navigable point of the Lancaster Canal, near Carnforth in Lancashire.

It marks the effective southern terminus of the upper canal section, as the link beyond Tewitfield towards Kendal has long been closed to navigation.

The marina is accessible to all craft using the connected inland waterways, with a maximum vessel length of 77 feet 11 inches applying on the Lancaster Canal.

The site sits on the Lancashire and Cumbria border and offers boaters and canoeists a quiet, somewhat isolated destination — a quality recognised by the Inland Waterways Association, which has designated it a Silver Propeller Challenge location due to the relatively small number of visiting boats.

The broader Lancaster Canal is notable for its 41-mile lock-free main line, the longest such stretch in the country.
