Flannan Isles

Site overview: The Flannan Isles are a group of six rocky islands, with outlying skerries, which lie about 30 km west of Lewis in the Outer Hebrides. These islands provide a strategically placed nesting location for seabirds, which feed in the surrounding waters. This includes auks and Leach’s Petrels. In fact this is one of only seven known nesting locations in the EU.
