I don't know if this is a bridle path or not. This is in any case the start of the Rhyd-ddu path to the summit of Snowdon. It starts at the Rhyd-ddu station of the Welsh Highland Railway, where ample paid parking is available.

The best view to be had of these two lakes is from the Crib Goch, and they will be a long way below you.

The Bwlch Main (south west ridge) is a great way to descend from the summit of Snowdon, particularly on a winter's day. Great views all the way to the Irish Sea
