The Route
🏔️ Route Character
The Pony Path is Cadair Idris' classic line — a steady, scenic ascent from the south side that climbs through rocky mountain country to the summit plateau of Penygader.
It's a perfect counterpart to Snowdon, Tryfan, and the Glyderau in the Snowdonia cluster — quieter, wilder, and with huge views over the Mawddach Estuary.
🧰 Route Breakdown
- 1. Ty Nant → Lower Slopes — A gentle start on a wide, well-built path with views opening quickly toward the Mawddach Estuary.
- 2. Pony Path Steepening — The path becomes rockier and steeper — a long, steady ascent with big views behind you.
- 3. Upper Ridge — Exposed, atmospheric terrain with the final pull to the summit plateau.
- 4. Penygader Summit — A rocky summit shelter and huge views across Snowdonia — one of the best viewpoints in Wales.
- 5. Return via Pony Path — Descend the same way — steep, careful footwork needed.
