Windy Gyle is a hill in the Cheviot Hills, right on the border between England and Scotland. It lies on the border ridge, and like the other hills in the area is rounded and grass-covered. Although maps show the border passing right through the summit, the summit cairn lies a few metres north of the fence that marks the border. The cairn at the summit of this hill is named Russell's Cairn and has a small depression suitable for shielding about 15 people from the wind. There are good views from the summit north towards the Scottish Borders, Eildon Hills and Edinburgh.
