The Llanberis Path is considered the easiest path for climbing Yr Wyddfa (Snowdon), and it's particularly popular for first-timers. It has a very short steep climb in the beginning don't be put off by this, it then has a long, gradual ascent up to the summit, just over 9 miles up and down.

Gradual walk but don’t be fooled that’s it’s an easy 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!

The easiest but longest route to the summit of Mt. Snowdon

Good little spot to stop and take in the views. It's a stone throw away from the shops and ice-cream shops.
