Pensford Viaduct River Chew Loop

The Pensford Viaduct spans the River Chew valley on sixteen arches, a striking Victorian railway relic that dominates this gentle 7.2km loop through the Somerset countryside south of Bristol. The route follows the river through water meadows and open pasture, passing beneath the viaduct before continuing along quiet lanes and field paths through a landscape of hedgerows, willows and damp grassland. The River Chew is a modest, winding stream here, but its valley floor is rich with wildflowers in spring and the atmosphere is calm and unhurried. The terrain is almost entirely flat with just 50 metres of climbing. Seasonal flooding can affect the lower meadow sections after heavy rain.

Off-lead potential on this dog friendly walk is limited as the route passes through livestock fields where cattle and sheep graze, so leads should be kept on through the pastoral sections. The River Chew provides water access for paddling and drinking at several points, and the meadow paths carry good scent from wildflowers and damp grass. The paths can be very muddy through the water meadows in winter and after rain. Pensford village has parking and the Rising Sun pub welcomes dogs. The viaduct itself is worth pausing at, its scale surprising in this quiet valley. A peaceful walk best appreciated at a slow pace, and well suited to older or less energetic dogs that enjoy riverside pottering.
