  • Our friend told us about the Electric Mountain and we decided to visit. We had no idea what it was but the bus tour 1hr 10mins and video and on and off bus commentary explained all. As it is a hydro-e...  more »

  • Good tour and facilities, but would have loved to have seen more of the power station and not just two of the levels. I think the film presentations could also be shorter as you've paid to see the power station, not films, plus the guide told you just about the same info that was in the films anyway. Great guides by the way, friendly and helpful 👍
  • Having driven up from Cardiff, for a long weekend, this was a pleasant surprise. The site is amazing, and definitely not something that you will find anywhere else. well priced. The tour guides were very friendly and knowledgeable. Even the bus driver was an ex-school teacher, able to keep the younger children enthralled with the mechanics of the sites construction and operation. The cafe and visitor centre could do with a bit of a refresh - there were no menus out when we visited, and so did not know what food options were possible. Also we did not know that there was a climbing wall there until we were leaving. Some improved signage would have helped.
  • This could be so much better. You only get to see a very small part of the facility which basically consists of a valve, turbine shaft and a hall where the tops of the shafts are. No visit to the control room or even just a mockup. The information in the videos are just repeated by the guide and on the boards but even that was incorrect throughout. All in all it was a bit disappointing. Done it now and i very much doubt ill return.
  • Great for kids and students. Well organised tour. Make sure you check the schedule and book ahead when possible to avoid long wait
  • 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.
