Llyn Dinas is a picturesque 24-hectare glacial lake in Eryri (Snowdonia) National Park in North Wales, near Beddgelert in the Nant Gwynant valley. It is a popular spot for scenic walks, wild trout fishing, paddleboarding, and swimming.

There are many, many ways up Yr Wyddfa (Snowdon), though the Watkin Path is one of the six trails officially recognised by the national park authority. It's a quieter option than the routes from Llanberis and Pen y Pass and also one of the most strenuous. It was also the first public footpath in the UK when it was inaugurated in 1892 by Prime Minister William Gladstone.

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

Great little station and you can get a good view of the little trains here. It's also a jump off point to climb Moel Hebog.
