Nant Gwynant

Nant Gwynant is a valley in north Wales. The A498 road descends 600ft into the valley in about two miles (3 km) from Pen-y-Gwryd; it follows the Nant Cynnyd, the Afon Glaslyn and alongside Llyn Gwynant, then beside the Nant Gwynant river to Llyn Dinas and passing below Dinas Emrys to Beddgelert. The road continues through the Aberglaslyn Pass to Porthmadog. The upper section of Nant Gwynant, from the site of the Roman fort and marching camp situated at the junction with the modern A4086 Caernarfon to Capel Curig road, follows the valley of Nant Cynnyd to a viewpoint (in about a mile) overlooking the Cwm Dyli hydro-electric power station, which was built over 100 years ago by the North Wales Power and Traction Company to supply electricity to the Porthmadog, Beddgelert and South Snowdon Railway that failed before it was completed. The power station however still uses the waters of Llyn Llydaw to generate electricity for the National Grid (UK).
