The Crana River is a 12-kilometer spate river in County Donegal, Ulster, Ireland, drawing its waters from Slieve Snaght and the Eskaheen Mountains before flowing northward into Lough Swilly near the town of Buncrana on the Inishowen Peninsula. As a classic Irish spate river, the Crana is intimately tied to rainfall, running high and colored after rain events and dropping back to low, clear conditions during dry spells. The river flows through a varied landscape — its upper and middle reaches passing through upland terrain before descending through agricultural pastureland, then through low-density urban development and semi-natural parkland in Buncrana town as it reaches the sea. The Crana is managed by the Buncrana Angling Association and is part of the Wild Atlantic Way experience, offering visiting anglers a genuine west-of-Ireland spate river fishery for Atlantic salmon, sea trout, and brown trout.
