Family-Friendly Electric Mountain, Caernarfon
Easter to end Oct: Tours available daily (advance booking essential.)
Adult £8.50, Children £4.35

The Electric Mountain is the visitors’ centre for the First Hydro Company (a major electricity generator in North Wales), and the attraction is so much more than just a power station.

The power station is set inside Elidir Mountain. That’s right – Elidir Mountain is hollow, and you can only take a trip around Electric Mountain by heading deep inside the mountain itself. You can then take an interesting and intriguing tour around the centre, seeing the largest power station of its kind in Europe at work, and learning about just how it generates its green power.

The underground chambers are seriously large, looking rather like the lair of an old-school James Bond villain. They are so large, in fact, that you are able to tour them by bus!

There are ten miles of underground tunnels here in the mountain, and once you’re done exploring the fun isn’t quite over. There is still The Den to enjoy – a fantastic soft play area for younger children – as well as a lovely café in which you can stop and catch your breath for a while.

If you haven’t had quite enough with all these exciting activities, why not give your brain a bit of a workout at Genius Corner? There are plenty of entertaining games, quizzes and experiments to enjoy.
