The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

The Walnut Tree Viaduct spanned the valley between the ridges of the Garth and Castell Coch. The one remaining brick pillar is all that remains of this massive structure.
