The Glyderau: Moonscapes and Monoliths 2026 Open Group Dates: Saturday 9th May 2026 Sunday 4th October 2026 £75 per person | Small Group Journey | Guaranteed to Run The Glyderau range offers a classic mountain walking day covering the three highest peaks in the range: Y Garn, Glyder Fawr, and Glyder Fach. All three are 3000ft giants. This is the perfect choice for those looking to move beyond Snowdon or gain confidence in a more rugged and craggy mountain environment. THE ROUTE: Starting from the Cwm Idwal visitor centre, we ascend the northeast ridge of Y Garn (946m) for incredible views over the valley. After a descent to the high mountain lake of Llyn y Cwn, we tackle the rocky slopes of Glyder Fawr, the highest point of the day at 1001m. We then traverse the weird and wonderful moonscape of the plateau, passing the splintered shards of Castell y Gwynt to reach the summit of Glyder Fach and its famous Cantilever Stone. The 12km circular route involves 1000m of ascent and returns via the stepped paths of Cwm Bochlwyd. CORE HIGHLIGHTS: The High Plateau: Explore the unique rock formations that make the Glyderau look like another planet.
