About Inishtrahull
Inishtrahull is a small island off Malin Head on the north coast of County Donegal and represents the northernmost island feature of Ireland. The island includes a lighthouse complex and is largely uninhabited today.
The island is noted for its lighthouse buildings and seabird habitat rather than visitor facilities; landing is possible but weather-dependent and rarely serviced by regular ferries. Visitors typically approach by private boat or charter and should expect rough seas and limited landing points.
Historically the island supported a small permanent population and served as a navigational point for shipping; the lighthouse and ancillary buildings were maintained to support navigation and were automated in later decades. The island no longer has a resident community and is visited mainly for maintenance or wildlife observation.
Geographically it lies off Malin Head at the northern tip of County Donegal in the North Atlantic, marking the extreme north of the island of Ireland. The surrounding waters are open and exposed to Atlantic weather.
