London, England offers a side of the capital that unfolds on towpaths, heaths, and woodland edges. Follow the Thames Path from Putney to Barnes for broad river views, trace the Grand Union Canal from Paddington, or head out to Epping Forest and the Lea Valley Walk. From Regent's Park to Biggin Hill and Totteridge, London rewards walkers with green corridors, old villages, and long miles that feel far from the city rush.
