Hydroelectric power plant

I thought it was all excellent - very friendly staff from the moment we arrived right through to cafe and the tour. We ordered bacon rolls in the spacious clean cafe and delighted to receive very generous portions. Food was very well priced as was the entry fee at only £7.50 for adult and £2.50 for a child. The tour itself was great, really cool going through the tunnel and amazing to see how it generates the electricity. Our two guides were really helpful and funny. Overall a great experience and as tour is only an hour its easy to stop, do the tour, then continue on to next destination. Would advise booking it though as its popular! very easy to book online through their site. 10 out of 10 overall it was excellent for a short informative tour.

Very wonderful place to spend the weekend time with the family

Amazing and fascinating to see the mechanics of this pump-store station in such a beautiful, rural setting

What a fantastic place. The views are amazing. We will go back again next time we are in Wales.

Amazing beautiful place ...what a fantastic day ...climb at the beginning is a bit harsh but levels out ...well worth a visit on way up to Ben cruachan

Worth visiting dam surrounded by natural beauty

You CANNOT drive up and park at the dam. You can at Cwmorthin Waterfall carpark or on the side road, both for FREE. The walk up the dam, on the tarmac road, took about 1h with 5 kids (13 to 5 years old) fantastic spot on a beautiful day, scenic view all around. We stopped at the dam but you can cross it (we saw people go over the fence) and continue hiking to the tip of the surrounding mountains.We stayed about 3h in total, so worth the hike!

Looked good for a swim

Such an awesome piece of engineering in the mountains. Stunning place too. The views are great and it's so so quiet at the top of the dam. Would love to explore more. We went to the visit centre too which was interesting.

Such a great walk, up Cwmorthyn over the Bwlch, then across the tops through old quarry workings and past explorable caves (take a hard hat and wellies and rope, then down over the top if the reservoir dam
