Through the forest run many paths, wide gravel paths but also narrow paths between the trees.

Llyn Llywelyn is a small shallow mountain lake surrounded by open moorland and forests. It is a natural spot to pause, picnic and soak up the serene atmosphere before continuing your walk.

The path along the lake is very nice. Part of it is actually a kind of dam you walk on, with a barrier on both sides so you have to stay on the path. Because the dam is elevated, you have a good view of the lake and the surroundings.

A crossing of the Welsh Highland Railway that you must cross carefully to enter the forests of Beddgelert. The Welsh Highland Railway is a restored narrow-gauge railway with a track gauge of 597 mm (1 ft 11+1⁄2 in) in the Gwynedd region (Wales).

Stop, look out and listen are the recommendations (to be read on the sign) that you must follow when crossing the track here. It is an unguarded crossing on this railway for tourist trains.

I think the start and the end is probably the hardest but overall pretty easy path you can’t get lost
