Giant's Cave, Wye Valley

Highlight • Cave

There are a couple of caves in this area. The first (coming from Chepstow) is very shallow and raided above the path.

The second "Giant Cave" has outstanding safe viewing platform outside it, and the cave actually opens into a secondary exit allowing passage through the rock.

This is a natural formation it would appear. Highly recommended!

In 1975 the Wye Valley Walk opened with a 14 miles (23 km) stretch between St. Arvans and Monmouth. Further stretches were added, leading to it becoming a 34-mile (55 km) footpath by 1981. During the 1980s, gaps between Ross-on-Wye, Hay-on-Wye and Rhayader were integrated into the pathway, forming a 112 miles (180 km) walk reaching from near the river's mouth at Chepstow in Monmouthshire, to Rhayader in Mid Wales

In September 2002, the route was finally extended to start or finish in Coed Hafren, having passed within viewing distance of the source of the River Wye on Plynlimon near Aberystwyth, a total of 136 miles (219 km).
