Rough Island is a tidal island in Rough Firth off the Solway Firth, Scotland. It is 24 m (26 yds) at its highest point. Since 1937 it has been in the ownership of the National Trust for Scotland. The island is a bird sanctuary accessible across the causeway from Kippford when the tides allow but visitors should avoid doing this during the months of May and June to avoid disturbing the nesting oystercatchers and ringed plovers.
Rough Island is one of 43 tidal islands that can be walked to from the mainland of England, Wales & Scotland and one of 17 that can be walked to from the Scottish mainland.
