The Ver-Clone Valley Walk is a walking route in Hertfordshire which follows the Ver and Colne rivers and which visits several former watermills and wildlife habitats along the way. The route is marked on OS Explorer mapping and is waymarked. From the beginning of the walk at Redbourne the walk follows the River Ver south via Redbournbury Mill, Shafford Farm and Bow Bridge to St Albans. Herre it passes Vervlamivm Roman Town, The Lake, Cottonmill Bridge and Sopwell home Farm before heading south from St Albans to Park Street (How Wood), and to pass under the M25 London Orbital near Moor Mill (Colney Street) before heading to Meriden, north-east Watford. Here the River Ver is left and the last mile is travelled along the River Colne in Watford.
