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.

Pont Scethin is a stone single arch bridge in a superbly wild and lonely setting in the Rhinog foothills. The bridge used to be on the old London to Harlech packhorse and drover route, and is probably 18th century. Source: https://coflein.gov.uk/en/site/24197/
