This is a great place to visit.Believe it or not this is the entance to a Power Station buried deep inside a mountain in Llanberis,North Wales.UK.It's about a mile inside the Mountain and you can go on a visit,great fun and very impressive.It's a Hydro Power Station.Because it's in The Snowdonia National Park it's impact on the landscape was slight,in fact if it was'nt for the visitor centre and the massive security no one would know it was there.For obvious reasons no cameras are allowed so any cance of photographing the massive turbines is a bit of a let down.
