Llyn Dywarchen


Folklore surrounding Llyn Dywarchen recorded in the 12th Century.

Gerald of Wales within his Itinerary through Wales. where he explains about a tradition concerning a 'one eyed fish'. The fish is actually an island which appears to float and move around on the lake. Overall it depends on which shore line the island is viewed from, but it certainly does give you the impression of movement over the water. Llyn Dywarchen is situated above the Nantlle valley on a plateau before the land massifs rises up to Yr Wyddfa (Snowdon).









Thomas Pennant later described the same lake during his grand tour in the mid to late 18th century. He noted the wonder which Gerald had described, and further added how cattle got caught on the island when its adjouned to the lake shoreline. Specifically when the wind starts to blow, thus moving the island into the lake to roam complete with its acquired passenger.

Llyn Dwarchen holds a

Llyn Dwarchen holds a special palce in my heart... it's one of the local places I hold dear to me. One of my favourite things to do is take myself up there on summer evenings and just be with the place - it's got a very old feeling to it; set in the glacial mountains with moorland all around. And yes, the island does seem to moveLaughing

Really glad to see these photos here!
