If you are on a bike please go around the footbridge on the roads though.
This trail uses a mixture of footpaths, country lanes and road-side pavements to take you on a tour of the lake and its surrounding countryside.
The route starts in the village of Trawsfynydd and heads west to the water where you cross the lake on the footbridge. There's great views in all directions as you cross the narrow bridge. The path then climbs through the woodland and countryside on the western side of the water. This section is quite challenging with the path reaching a height of almost 1000ft (300m).

This is a shared walking and cycle path with bike hire available at the visitor centre.
If you would like to continue your walking in the area you could head west and climb to the fascinating stone circle at Bryn Cader Faner or the nearby Foel Penolau in the Rhinogydd range. The Taith Ardudwy Way long distance trail can be picked up near here too. View Full Details>>
