About the garden

Owned by
Ian and Charlotte Knott Sinclair

This peaceful 12-acre garden has magnificent views over the Mull of Galloway with two lakes forming the centrepiece with tender plants from around the world thanks particularly to the North Atlantic drift. There are comprehensive, well labelled garden and tree trails plus moorland walks. Discreet sculptures and seats feature throughout.

Glenwhan Garden in Gaelic means 'green & rushy place', which aptly describes the site four decades ago, where there existed only bracken, gorse and the odd willow. Now a wealth of plants, some tender, from around the world have matured and thrived, with the help of the gentle influences of the Gulf Stream, created as a 'labour of love'.

There are stunning views over Luce Bay & The Mull of Galloway, to the Isle of Man, with winding paths round lakes, and well-placed seats on which to relax and admire the view. The moorland walk with more than 120 species of wildlowers and grasses, together with a designated tree trail, and a wealth of wildlife all add to the attraction of what has been described as one of Scotland's most beautiful gardens.

Many of the plants seen growing in the garden are available in the nursery. The tearoom has Scotland's 'Taste Your Best Award', uses local seasonal ingredients and is a welcome break for the visitor.

The views from the top of the garden take in Luce Bay, the Mull of Galloway and the Isle of Man. There are many winding paths with seats placed at the viewpoints, and some interesting pieces of sculptor thoughtfully placed. Red squirrels, a wealth of bird life and the odd peacock may be spied. Adjoining the gardens are the extra bonus of a 20-acre moorland walk, for the visitor to explore.

A new designated tree trail for the dendrologist and comprehensive list of species rhododendrons has been added.
