Sygun Copper Mine

This mine dates from Roman times, although extraction was stepped up in the 19th century. Abandoned in 1903, it has since been converted into a museum, with a half-hour self-guided underground tour containing dioramas that evoke the life of Victorian miners. You can also try your hand at metal detecting (£2.50) or panning for gold (£2). It's located a mile northeast of Beddgelert, along the A498.
