There’s a little-known valley near Bolton Abbey called the Valley of Desolation, named after the damage caused by a storm in 1826. It’s close to one of the most popular visitor sites in the Yorkshire Dales but you’ll find relatively few people there. When the trees get their autumn colour it becomes a spectacular sight of oak, birch, rowan, bracken and brambles. In summer the dominant colour is green. It’s a good spot for an overcast day.
