Some of the best 360โฐ views you'll get over Snowdonia, Anglesey and Llyn peninsula from the vantage of this great shelter with built in seats

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.

I think the start and the end is probably the hardest but overall pretty easy path you canโ€™t get lost

Great view of the lake and the climb to come , stopped for a quick brew before the ascent up

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.
