There are many walks that will take you to, and along, the Great Ouse which vary in length, sights and ease of access.
It’s perhaps the epic walk from source to sea and here is an overview of the route with the things to see and do along the way.
A set of printable leaflets for the middle part of the walk, from Eaton Socon to Earith, has been made available by the Great Ouse Valley Trust.
If it’s the Fens that fascinate you most, then why not follow the Fen Rivers Way from Cambridge up to Ely where this walk merges with the Ouse Valley Way and continues to King Lynn. Norfolk Council have provided this information.
Following the Bernwood Jubilee Way provides an interesting alternative starting point to the Ouse Valley Way. This follows the course of Padbury Brook (the Twins) and feeds into the Great Ouse. Buckinghamshire Council have produced a set of downloadable walking routes.
Progress through the Slough of Despond in the footsteps of John Bunyan. The Wildlife Trust have produced a downloadable trail booklet.
The Rothschild Way is a fenland footpath commemorating the conservation work of Charles Rothschild. The route is undertaken by a number of people annually in June through the Rothschild Way Challenge event which raises funds for work on the Great Fen.
If you’ve finished the Ouse Valley Way and want to see the sea, why not continue walking up to Hunstanton on the King Charles III England Coastal Path.
