MARK Glyder Fach & Glyder Fawr
Glyder Fach and Glyder Fawr form the shattered, lunar-like heart of the Glyderau — two high, dramatic summits built from broken tors, tilted slabs, and jagged rock fields. The traverse between them is one of Snowdonia's great mountain routes: rugged, atmospheric, and packed with huge views across the Ogwen Valley, Nant Ffrancon, and the Snowdon massif. Whether approached via Bristly Ridge or the Miners' Track, this is a proper mountain day with serious terrain and unforgettable scenery.

The Route
🏔️ Route Character
The Glyderau are wild, dramatic, and unmistakable — a landscape of shattered tors, tilted slabs, and huge rock fields that feel almost alpine. The character shifts throughout the day: Approach — steep, rocky, atmospheric; Glyder Fach — jagged summit, Cantilever Stone, huge views; Glyder Fawr — broader, higher, more open; Descent — long, rugged, and scenic.
It's a big mountain day with serious terrain, but no technical scrambling unless you choose Bristly Ridge as your ascent line. This is one of the most iconic traverses in Snowdonia.
🧰 Route Breakdown
- 1. Ogwen Cottage → Bwlch Tryfan — A steady climb on rocky paths. Tryfan rises to the left; the Glyderau tower ahead.
- 2. Ascent Options — Bristly Ridge (Grade 1–2) — steep, exposed, dramatic; or the Miners' Track (non-scrambling) — rugged but straightforward. Both lead to the shattered plateau beneath Glyder Fach.
- 3. Glyder Fach Summit — A jagged, atmospheric top with huge views. The famous Cantilever Stone sits nearby — a perfect photo spot.
- 4. Glyder Fach → Glyder Fawr Traverse — A rugged, rocky crossing over broken ground. Big skies and huge panoramas throughout.
- 5. Glyder Fawr Summit — The highest point in the Glyderau. Broad, open, and dramatic, with views across Snowdon, Y Garn, and the Carneddau.
- 6. Descent Options — Devil's Kitchen → Llyn Idwal → Ogwen — classic, scenic, steep; Y Garn → Ogwen — big horseshoe; Reverse traverse → Bwlch Tryfan → Heather Terrace → Ogwen — safest in poor weather.
