Between the two lakes is Hafod-y-Llan (bought by the National Trust in 1998) with the Watkin Path climbing above Afon Cwm Llan to the summit of Snowdon. The path starts in South Snowdon Quarry, which was later the intended destination of that never completed narrow gauge railway from Porthmadog. The path, which was ceremonially opened in 1892 by William Ewart Gladstone the then Prime Minister, was specially constructed for Sir Edward Watkin, railway entrepreneur and Victorian pioneer of the Channel Tunnel for the benefit of guests at The Chalet, his summer retirement home in the woods.
