Clogau Gold Mine

The Clogau mine was once the largest and most productive gold mine in the area. Miners quarried over 165 tonnes of minerals between 1862 and 1911—over 2 tonnes of which was gold.

In 1899, £60,000 worth of gold was extracted from Clogau—equivalent to over £8m in today’s money.

Gold mining does not take place in Wales today, and the supply of Welsh gold may eventually run out, making it possibly the rarest gold in the world.

Shipbuilding on the Mawddach

The route offers phenomenal views of the Mawddach estuary. During the 18th and 19th centuries, the estuary was a busy shipbuilding centre. Boats and ships were built towards the Penmaenpool area and towed along the estuary to Barmouth, where the sails and rigging equipment were installed. A total of 318 vessels were along the Mawddach between 1750 and 1865.

Eryri’s Industrial Heritage

Clogau is one of several industrial heritage treasures strewn across the National Park. Nearby gold mines such as Gwynfynydd were also active during the late 19th century. Other mining sites include the Sygun copper mine at Nant Gwynant.
