The second stage starts off up the lovely Wye Valley and cuts into Mid-Wales,
Some of the places I will pass or plan to visit each day:
day 3: Severn Bridge to Llandogo (via Chepstow)
Strictly this is the last mile or two of the Wales Coast Path before picking up the first stage of Offa’s Dyke
- Chepstow
