Huntingdon and Godmanchester Walk, Houghton Mill
Loops along the Great Ouse valley between two historic market towns, crossing meadows and riverside paths with minimal incline throughout. Flat terrain suits families with older children capable of the distance, though mudgy stretches after rain make buggies impractical. Dogs welcome on leads near livestock and at National Trust's Houghton Mill (stunning 17th-century watermill worth the stop). Peaceful countryside walking with plenty of river views and good pub options in both towns.
