Here, a short distance from Oban, you can discover one of the hidden wonders of the Highlands. A power station buried one kilometre below the ground.
At its centre lies a massive cavern, high enough to house the Tower of London! Here enormous turbines convert the power of water into electricity, available to you in your home at the flick of a switch.
