The Dinorwig Power Station is a leading example of cutting edge science, technology and engineering. The knowledge, skills and application required to create the largest man-made cavern in Europe and operate some of the world's most powerful generators, are an ideal illustration of power and the importance of STEM (Science, Technology, Engineering, Mathematics) in our everyday lives.

Hands-on interactivity is significant in the knowledge and understanding a child has of science and can have a lasting impact on attitude and understanding. Similarly, they can promote trust and understanding.

The Tour

Located beneath the ancient Elidir Mountain's labyrinth of dark and imposing tunnels, you'll experience one of man's greatest engineering achievements. The tour starts with a sound and vision spectacular at the visitor centre illustrating the role that pumped storage plays in ensuring the country's electricity demands are always met. We then take a bus that descends deep into the mountain taking us to the three main caverns. When it was excavated this cavern was big enough to contain St Paul's Cathedral!
