The Dolaucothi Gold Mines, also known as the Ogofau Gold Mine, are ancient Roman surface and underground mines located in the valley of the River Cothi, near Pumsaint halfway between Lampeter and Llandovery.

The gold mines are located within the Dolaucothi Estate which is now owned by the National Trust. They are the only mines for Welsh gold outside those of the Dolgellau gold-belt, and are a Scheduled Ancient Monument.

There is evidence of Roman gold mining at the site dating back over 2,000 years. Mining on this site continued into the twentieth century, ending in 1938.

The National Trust offer regular guided tours which include going underground into the mine itself, ending with the chance to try the gold panning experience. Tours must be pre-booked.

Underground tours involve an active outdoor visit up steps and steep slopes. Appropriate outer wear and stout enclosed footwear is essential. Children must be at least 1m in height.

Site entry including the guided tour costs £12 for an adult or £30 for a family (September 2023). Entry is free for National Trust members.
