  • Good excursion, you are being picked up by a buss, where they are taking you to a power station inside the mountain. There are miles of tunnels inside it. They show you and explain how the power station works and how it was built. Worth a visit. Not that expensive.
  • Well worth booking this very unusual and interesting trip. You meet at the visitors centre where you are shown a short film. Then you have to stow your belongings in a locker after which you're taken by bus to the power station pump, turbine and generator hall located down tunnels nearly 1 mile under the mountain! Don't worry, not much walking required plus you get to wear a hard hat.
  • Fascinating place to visit and learn about Pumped Storage Hydro Electric Power, the generating hall is quite awe-inspiring not just from the generating plant but also the sheer size of the cavern. Travel around the site is by coach with several stopping off places. Top tip, book early to avoid disappointment as the attraction is popular and spaces are limited.
  • The introductory video and the tour guide gave an easily understandable explanation of the history and workings of the power station, while still giving detailed info to the scientifically minded. Would have liked to see more parts of the facility but the areas shown were still impressive. A major thing to note is that no electronic devices are allowed on the tour, including cameras and phones.
  • very nice place to go but you will need to book online i got turned away has i never booked online
