Bedford has been described as one of the finest riverside settings in England and the River Great Ouse is the jewel in Bedford's crown. Along with its tributaries, the Rivers Cam, Lark, Little Ouse and Wissey, they comprise the major navigation in the Fens and East Anglia, providing about 240 km (150 miles) of navigable waterway, flowing through some of the most unspoiled water environments in Britain.
