A Walk around Cwm Idwal Details

The dramatic Cwm Idwal feels rugged and mountainous but is still a straightforward family walk with very little ascent considering the terrain. The view across Llyn Idwal is dominated by the craggy facade of Twll Du or The Devil’s Kitchen. While the path is good around most of Cwm Idwal, there are some rougher sections especially as you reach the start of the Devil’s Kitchen ascent.

For a bit more interest, you can take the higher path toward’s Twll Du / The Devil’s Kitchen  rather than cross at the lake’s head.

The Route

We’ll be refreshing our circular Cwm Idwal walking route in the spring with new content and images. It’s a straighforward walk from the visitor Centre – with the loop around the cwm’s backwall adding some challenge if you wanted o add to the walk. You can decide to walk only to Llyn Idwal and back if you find the going too hard. The main thing to keep in mind is that you cut across the head of Llyn Idwal early enough and that you don’t continue on to Twll Du by mistake. Note that the crossing can be a little wet, so ensure you’ve got proper boots!
