Another Scotland recommendation- Ben Cruachan hydro dam has a nice visitor center. Its on the west coast.
I work for Vandebron in the Netherlands. Some of our smaller producers are happy to show visitors around. It helps if you are one of the households they are supplying of course ;)
Ben Cruachan is great and free if you come by train. The walk up to the top is good on a nice day but not easy. I went in the summer and there's a photo at the bottom of this blog post: https://unop.uk/mobile-gb-rail-live-departure-boards/
Yes, I also climbed it once, on a fantastic clear summer day. The view was amazing, could see many of the islands from the summit. Would love to do it again sometime.
