Cambridgeshire, England rewards walkers with big skies, reed-fringed waterways, and paths that linger in the landscape. Follow the Fen Rivers Way past Ely and St Ives, circle the open water at Grafham Water, or step onto the Wicken Fen Boardwalk among sedge, marsh, and birdsong. Around Houghton Mill and the Hemingfords, the county’s gentler trails carry the calm, expansive character of the Fens.
