Winning tip: burial chamber, Betws-y-Coed

Brooding high up in the hills above the Conwy valley in Snowdonia lies Capel Garmon burial chamber, an almost symmetrical three-chambered Cotswold-Severn-style neolithic tomb, denuded and exposed to the surrounding peaks, sheep and tempestuous climate. Sited in a field with easy access from the road or marked footpaths, it makes a great mini pilgrimage on foot from Betws-y-Coed (approx three miles), or parking is easy, just under a mile south from Capel Garmon village.
