Pitlochry is famous for its hydro-electric dam and salmon ladder. The ladder was specially constructed to enable salmon to by-pass the dam and make their way upstream to Loch Faskally above. It is estimated that approximately half a million visitors go to the dam and fish ladder every year, making it one of the top attractions in Scotland. The ladder is 310 metres long and consists of 34 chambers. It enables around 5,000 salmon to return to their spawning grounds each year - a journey of some 6,000 miles!
