Cadair Idris

£77.00

Sunday 5th July 2026

Make it a full weekend adventure?

Book with Snowdon Pyg Track for £10 off.

Experience this iconic Welsh peak, literally meaning ‘Chair of Idris’, and the wonderful crater lake at the foot of the mountain’s face. With a very light non-graded scramble at the summit, this is a very exciting and enjoyable walk that has a beautiful charm all of its own.

Cadair Idris feels like the perfect bridge between your earlier adventures on Pen y Fan and the bigger days still to come on Snowdon. You’ll walk through dramatic glacial scenery, stand beside the stunning Llyn Cau (one of Wales’ most beautiful mountain lakes), and finish with that rewarding final push to the summit. On a clear day the views stretch across the Mawddach Estuary, the Rhinogs, and out to the sea — a true highlight of Eryri National Park.

Trip Highlights

  • Climb the legendary Cadair Idris (the ‘Chair of Idris’)

  • Visit the spectacular Llyn Cau crater lake nestled beneath the cliffs

  • Enjoy a short, fun non-graded scramble near the summit

  • Perfect stepping-stone peak between Pen y Fan and Snowdon

  • Stunning panoramic views across Snowdonia and beyond

  • Small-group guiding
