The Ugly House, or Tŷ Hyll, is a squat stone cottage on the road between Betws-y-Coed and Capel Curig, with a look that seems built for Welsh folklore. Stories connect it with the old tradition of a house raised overnight claiming rights to the land, though the romance is easier to enjoy than to prove.
It is a small sight, but a good one if you are already exploring the wooded roads around Betws-y-Coed. The cottage, garden, and surrounding trees give a gentler pause between waterfalls, mountain views, and longer Snowdonia walks. It is best treated as a characterful stop rather than a main destination.
