Loch Earn ... a seiching Loch?
Loch Earn, excavated by the awesome power of ice glaciers, has "bonnie banks and braes" along its 7 mile length. It is a narrow loch about half a mile wide. Its western boundary lies at Lochearnhead at the foot of Glen Ogle and its reported depth is almost 300 feet.St Fillans, a charming little village lies at the east end, and here the River Earn exits.
Loch Earn is surrounded by hills with Ben Vorlich (985 Mtrs) to the south and the scenic pass of Glen Ogle to the north west. The railway viaduct in Glen Ogle marks some heroic effort to extend the railway services across all of Scotland. Here the line did not last because of the high building and maintenance costs in this rugged and dramatic terrain.Good use has been made of the route however, and Sustrans cycling route 7 passes along its length.
Loch Earn is unusual due to an tidal like effect, "seiching", caused by wind along its length and by thermal stratification and is one of only two Scottish Lochs to be so affected. Lake Geneva is probably the best known loch with similar "tides".
Edinample Castle lies on the southern shore near Lochearnhead and is a reminder of the need for security in a land where cattle rustling was endemic. Rob Roy McGregor was probably the best known of these. The remains of several Crannogs can be seen in the Loch, particularly during dry spells
There are many hotels with restaurants on the northern shore of the Loch and fishing, water skiing, wakeboarding, kneeboarding at Lochearnhead and sailing at Loch Earn Sailing Club, being popular with visitors. To ensure equal enjoyment by all a code of conduct has been agreed for users of the loch.
