The Wye Valley Walk is a 136 mile (218km) walk from Chepstow to Plynlimon, following the entire length the river Wye. Due to the heavy rain, I had to miss some of it. I will definitely be back with my family to do the walk in its entirety. I really enjoyed the path, it was more interesting than I had expected. In better weather it is an excellent family or first long distance walk.
