Allt Fawr

Allt Fawr is a 2,290ft mountain overlooking Blaenau Ffestiniog and the Llechwedd Slate MinesThe reverse view takes in the whole Snowdon Horseshoe, Moel Siabod & the Glyderau mountains.

The wander up from Blaenau side is fairly steep yet with comfortable grass covered paths, seldom walked by tourists. It’s a truly beautiful place to be in the right light, with mountains stretching out for miles and miles in every direction.

Allt Fawr Walking Route 3D Map | The Frozen Divide

The Allt Fawr Horseshoe trail route is a winner for avoiding the crowds on hot sunny days, while still retaining incredible views over Snowdonia National Park. Our circular loop takes in 4 summits, a number of lakes and miles of completely off trail wandering (i.e. no paths for long sections).

1. We park at one of the car parks on the A470 main road to the north of Blaenau Ffestiniog town. Hopping over the fence we ascend quickly to meet the marked footpath to the summit of Allt Fawr, with the view over Blaenau to our left.

2. The 360 views from the top of Allt Fawr are incredible, and it’s a hard summit to leave. From there we head east, taking in Moel Druman and Ysgafell Wen as well as dog legging a bit to see a few of the many small lakes up here.

3. Heading north after Ysgafell Wen we follow the ridge off trail all the way down to the valley floor and cross over the Afon Lledr river.

4. After a short bit of incline the miners path levels out as it wraps around Moel Dyrnogydd back to the beginning.
