  • A well organised trip with a good guide. It is interesting to see the scale of the underground works and what goes on there but the films and information were a little repetitive and it depends what m...  more »

  • The Visitor Centre is on the A486, about 1.4km from the Dinorwig Hydro Power Station, which is within a tunnel deep under the mountains. The Centre's setting itself is very attractive with the mountains as the backdrop. Visitors are taken by coach into the tunnel. First thing to do is to book tickets at the Centre. There's a decent restaurant where one could have something to eat or drink while waiting. If you have a longer wait, I would advise paying a visit to the National Slate Museum which is 950 metres away. It's free and could be an eye-opener. The power station is a great engineering feat. Off-peak electricity is used to pump water from the lake at ground-level into a reservoir at the top of the mountain. The water is then released at times of high demand to generate power. Mobiles phones, hand bags, rucksacks etc are not allowed. Lockers are provided at reception. The 45-minute tour is interestingly presented by the tour guide. You'll come out knowing where the blast of energy for the nation's cuppa is coming from.
  • It was a hot and sunny day when we visited this attraction. A welcome cool surrounding awaited under the mountain! Fascinating and interesting location. Coach takes you to the location with a guide to inform on all the relevant facts a little walking once inside to see the machinery etc. An engineer's pleasure. Well worth an hour of your time to see and a reasonable price. Recommended
  • 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.
  • 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 👍
  • One of the most beautiful places in Wales, I always love to go there and enjoyed a lot, we also had an awesome fish & chips there.
