Insh Marshes are an area of floodplain of the River Spey between Kingussie and Kincraig in Badenoch and Strathspey, Highland, Scotland. The marshes are said to be one of the most important wetlands in Europe. They lie at an altitude of approximately 220–240 m (720–790 ft) above sea level, and form one of the largest areas of floodplain mire and fen vegetation in Scotland.
The marshes cover around 11 km2 (4.2 sq mi), and hold a number of conservation designations. 7 km2 (2.7 sq mi) of the area is owned and managed by the Royal Society for the Protection of Birds (RSPB), and forms a national nature reserve. The RSPB have laid out several waymarked trails, and provided two bird hides to allow visitors to appreciate the area and its birdlife.
