Cwm Idwal Walk

Route Description for Cwm Idwal Walk

To start the Cwm Idwal walk, from the Ogwen Ranger Base, take the steps to the left of the building. Follow the main footpath ignoring the right-hand fork that leads up through a rocky crevice. Continue ahead through the gate a short distance further and cross the wooden bridge over the small, but roaring stream. There is a nice viewpoint from here down to Llyn Ogwen, don’t forget to look!

The footpath climbs gently, winding away from the stream. Approximately 500 m further up, the path again forks. Take the right-hand fork which follows the well-trodden stone path towards the lake.

Upon reaching the lake, Llyn Idwal, you can turn left or right depending which way you would like to go around the lake. We at 10Adventures prefer heading left, which is reflected on the map.The route around is pretty simple and extremely pleasant. The path is well maintained and it should be straightforward to follow. At the far end of the lake, you will need to drop off the main path and turn right to continue around the lake. This path leads you down to a levelled area where you will use stepping-stones to cross a gentle stream.

Follow the path around the lake shore, eventually crossing a slate bridge to finish the circular route of Llyn Idwal. From here, turn left to retrace your steps back to the Ogwen Ranger Base for a pick me up (ice-cream, tea and plenty more available)!
