A very good path - good enough for cycling - from Bwlch Maesgwm to the road above Llanberis. It is a beautiful valley with a feeling a remoteness.

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.
