Welcome

Loch Katrine lies deep in the Trossachs, a long loch winding west between wooded hills and mountains, and it has a fair claim to be the birthplace of Scottish tourism.

Visited and photographed by Simon Hird

In 1810 Sir Walter Scott set The Lady of the Lake here, and so many readers came to see it that the Trossachs became a place to visit. Rob Roy MacGregor was born at Glengyle at the loch's far western end, and his name was later given to its steamers.

In 1859 Queen Victoria sailed up the loch to open the waterworks that still send its clear water down to Glasgow. Since 1900 the steamship Sir Walter Scott has carried visitors from Trossachs Pier; restored at a cost of £850,000, she went back into service in 2023 and was named Flagship of the Year in 2025. Beyond the pier there are cafés, bike hire and a quiet road along the north shore, closed to most traffic, that makes a lovely walk or cycle ride towards Stronachlachar.

Hidden Scotland

From our guide to Loch Lomond & The Trossachs

Loch Katrine winds west for about eight miles between wooded hills, and it has a fair claim to be where tourism in Scotland began. Scott set The Lady of the Lake here in 1810, and so many readers came to see it that the Trossachs became a place to visit. Rob Roy was born at Glengyle, at the loch's far end. Since 1900 the steamship Sir Walter Scott has carried visitors from Trossachs Pier, and you can take a bike on board, sail to Stronachlachar and cycle back along the quiet lochside road.
