Excellent connecting ridge between Carnedd Llewellyn and Pen yr Helgi Du. FIne climbing and scrambling routes on the northern side, such as in the Amphitheatre.

The high pass between Tryfan and Glyder Fach is also a crossroads for a number of paths - down to the Ogwen valley, but also up to Tryfan and to Glyder Fach via the Bristly Ridge or the bypass route.

Beautiful hike, too bad it was cloudy at the top. 12.3 km isn't the actual distance you'll be hiking: it's definitely 10 km more because you can't walk a straight line on this path. It's very busy on this trail; there's a queue to reach the top.

Crazy hiking all the way up and then seeing a train pass you on the final section!

Magnificent and dizzying view! However, prefer to go around in the opposite direction to that indicated. The steep slope is very narrow and steep. Easier to go up than to go down.
