Amid the Welsh Mountains, serene lakes and dramatic landscapes – at the edge of the picturesque Snowdonia Park you will find the Electric Mountain Visitors’ Centre.

Once you enter the Visitors’ Centre you will be in a different world.

Firstly, you will be shown a video that will give you an idea of what you are going to see and experience

You will then be introduced to an Underground tour deep into Eliden Mountain, where you will be able to see, feel and hear Europe’s largest man made cavern in operation with some of the largest and most powerful hydro -generators in the world.

A bus will take you from Electric Mountain into the centre of the Dinorwig Power Station. You will pass through many tunnels – stopping every so often to get off the bus and see the magnificent generators close up. And learn how they can go from zero output to full power within seconds.

The pump storage system that produces electricity at Dinorwig relies on falling water to turn the turbines.

The whole generating system buried deep in Eliden Mountain is in a cavern that is large enough to house St Paul’s Cathedral.

While in action – as much water passes through the tunnels at Dinorwig as London uses in a whole day.

There are tour guides who are very knowledgeable and will patiently answer all questions you throw at them.

Once you have returned from a tour, you may enjoy a meal or snack at the Connections Café / Bistro. Or a browse around the shop may take your fancy. For sale are souvenirs and gifts.
