Cae Mabon is a retreat centre in North Wales, set in an oak forest close to the disused Dinorwic Quarry and on the opposite side of the Padarn lake from the town of Llanberis. The centre has been run by its founder, local storyteller, author, and songwriter Eric Maddern, since 1989 and is well regarded for the beauty of its natural setting as well as the architecture of its alternative, low-impact buildings.
