1. Bwlch

    Son of Cleddyf Cyfwlch, brother of Cyfwlch and Syfwlch, one of Arthur's warriors.

    He had a sword named Glas, a dog named Call, a horse named Hwyrddyddwg, a wife named Och, a grandchild named Lluched, a daughter named Drwg, and a maid named Eheubryd.

    He assisted Culhwch in hunting the boar Twrch Trwyth.

  2. Bwlch-y-Groes

    A pass through the mountains on the highest road in north Wales above Tan-y-Bwlch.

    Here lived the giant Rhitta, who had an penchant for collecting beards from the men he killed in order to make a cloak. One day, however, a man he picked on killed him and threw him down the hillside, where he was buried, presumably as he was too heavy to move and bury elsewhere. A path leads down the hill to Tan-y-Bwlch, which is known as Rhiw Barfe, 'The Way of the Beared One'. The giant's grave consists of a long, narrow trench surrounded by large boulders.

    The alternative site for this battle, and for the giant's grave, is Yr Wyddfa Fawr, or Mount Snowdon. This tale was later embroidered to make vanquisher of Rhitta none other than King Arthur himself, who obviously had no desire to part with his own beard, the fight occuring on the occasion when Arthur was travelling through the pass en route to visit Merlin.

  3. Bwlch-y-Saethu

    According to Welsh legend, Arthur was killed with arrows at this pass in Snowdonia, North Wales, whither he had pursued his enemies after a battle at Tregalen. When he fell, his men went to a cave called Ogof Lanciau Eryri where they had intended to wait until he came back.

    A shepherd was once thought to have gained entrance to the cave and seen them there. He found them armed with guns!

- Bwlch signifies a break or breach, generally found in place names where there is a narrow pass in the mountains.
