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.

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.

Beddgelert is a lovely village below Moel Hebog, and the bridge over the river is a key feature.

This is an example of many miles of the trail in Beddgelert Forest. Quite wide double tracks, compact gravel surfaces, enclosed by mainly pine trees. If it is a windy day and needing an area to ride in which is more sheltered from the wind, then Beddgelert Forest does offer just that

Tis is the crossing of the Ffestiniog Welsh Highland Railway at Rhyd Ddu. once through the crossing the surface becomes compact gravel and climbing. It is rideable but takes effort

Always handy to know a bike shop is within the area. Framed bikes is on the main street through Llanberis. The owner said there is a two to three week wait for work, but I got the feeling he would assist riders passing through
