Dyffryn Ogwen, or the Ogwen valley, is a fascinating place for amateur geologists, like me. The upper part of the Ogwen valley is relatively flat and expansive, with giant peaks along each side (the Glyderau and Carneddau ranges). But once you reach beyond the foot of Llyn Ogwen, or Ogwen Lake, the valley suddenly drops 100m/328ft in a series of waterfalls and rockfalls down into the long and pastoral part of the valley, known as Nant Ffrancon.
The sights at the cusp of this drop are absolutely incredible. Strewn boulders the size of cars litter the land with various trees, ferns, and wildflowers popping up wherever they can. Rhaeadr Ogwen, the Ogwen falls, cut a channel between the boulders all the way down to the valley bottom. Above the rift, you can just make out the peeping head of Tryfan (917.5m/3,010ft). Paradise.
