About
A family-run fossil, mineral, and gemstone museum and shop at Llanddyfnan, just outside Pentraeth in central Anglesey. The collection spans 650 million years of Earth's history, with dinosaur models, arrowheads, and one of the largest fossil displays in Wales alongside cases of crystals and stone jewellery for sale. It's a reliable rainy-day stop for families, combining hands-on exhibits with a shop counter for a fossil or gem to take home.

Is it suitable for children?
