Beautiful lake, but avoid the area at Easter!

Huge angled boulder that you can see from the valley below. It can be climbed with care, but is polished these days.

Rhaeadr Idwal is the scenic waterfall formed as the outflow of Llyn Idwal tumbles toward the Ogwen Valley. Cascading over ancient volcanic rock, it is a highlight of the approach path from Ogwen Cottage. Nearby, the Devil’s Appendix plunges 93 meters down the cliffs of Twll Du, making it the tallest single-drop waterfall in Wales. These falls are most dramatic after heavy rain or when frozen into spectacular ice columns in winter.

Tyrfan is a quite wonderful mountain, a great spire that rises straight up from the Ogwen Valley.

This route is so much fun - and is part of what is probably the best grade 1 scramble in Snowdonia.

The south ridge is the easier way to reach the top of Tryfan, but it still has it's moments near the top.
