The River Great Ouse and its tributaries, the Rivers Cam, Lark, Little Ouse and Wissey provide approximately 158 miles/255 km of navigable waterway.

The upper reaches of this river flow through some of the most peaceful and unspoilt waterway locations in Britain, offering a wide range of natural and historical sites and pretty rural towns to visit.  The lower reaches take boaters through the characteristic Fenland landscape with a skyline dominated by Ely Cathedral.

There are many sites of interest to visit along the river, including the Stretham Pump, Wicken Fen and the Pumping Engine Museum at Prickwillow.  The Ouse Washes is a site of special value to nature conservation, and Welney Wildfowl Trust is one of the best places to view wildfowl all year round./255 km of navigable waterway.
