Canvas Print of Maen Llia is a tall standing stone composed of red sandstone. It stands in the Fforest Fawr section of the Brecon Beacons in the Brecon Beacons National Park. Its location is near where the Llia Valley runs out and over into the Senni Valley. It is said that every so often the stone walks down to the River Llia for a drink! If you look closely you can see engravings of names in the stone. High hills surround the Llia Valley and the Standing Stone and the whole area is generally empty of people.
