Only a quarter of the Wye Valley is in Wales. The southern half of the river straddles the border between
England and Wales, while the northern half is entirely in England. The southern section contains a number of
features of interest, such as Tintern Abbey, some very interesting rock features, and Symonds Yat.. Offa's
Dyke starts here (or ends, depending on your point of view), but it's on the eastern English bank of the river.
