One path is a bit wider than the other, but most are gravel paths. Good for walking and/or cycling.

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

Slightly above Llyn Llewelyn you have a nice view of Snowdon and the surrounding peaks. Enjoy this beautiful view.

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.
