Great Orme Mines

Walk through tunnels mined out over 3,500 years ago, following the ancient passageways to the Great Cavern, the largest prehistoric underground excavation in the world.

Returning to the surface, the pathways will take you around the prehistoric landscape and to the Opencast Mine, the oldest part of the site, mined 4,000 years ago. See how our ancestors turned mineral into metal at the Smelting Shelter and learn about the 19th Century redevelopment of the site as you peer down the 145 metre deep Victorian mine shaft. See the collection of Bronze Age tools discovered on site at the Archaeological Store.

This very special attraction is also a place of ongoing archaeological study.

The gift shop sells a wonderful selection of fossils, gemstones, jewellery, books, maps and more, to suit a wide variety of tastes.

After touring the site, have a browse in our well stocked second-hand bookshop.

Dogs welcome.

No need to book, purchase your tickets on arrival.

Open mid-March until the end of October.
