Caldicot & Black Rock Loop
Loops through Caldicot's Nedr reserve and along the Severn Estuary to Black Rock viewpoint, mixing flat marshland boardwalks with gentle grassland paths. Mostly level terrain makes it manageable for older children, though muddy sections and stiles rule out buggies. Dogs welcome on leads near livestock. Worth it for big estuary views, wading birds, and the contrast between wetland wilderness and industrial Severn crossings on the horizon.
