As of August 2021 there are severe access issues with this small hill. Previously access could be had from Bunowen beach, just to the south, but halfway up you encounter a new, high barbed wire fence along with threatening warning signs. The historic castle is also apparently in private ownership so also remains inaccessible at this time. Linkback: https://mountainviews.ie/summit/5025/comment/19489/

O'Flaherty's castle built in the 1500s and for a time home to the legendary pirate queen Grace O'Malley. Linkback: https://mountainviews.ie/summit/5025/comment/19599/

Doon Hill is a small hillock, but is quite striking in that it occupies a pretty shoreline spot and because of the flatness of the surrounding area, may be seen from quite a distance. Linkback: https://mountainviews.ie/summit/5025/comment/23242/

During the time of Napoleon Bonaparte the powers in Dublin built a large number of signal towers all around the Irish Coast the ruins of one sits atop of Doon Hill .They were under British navy control with a lieutenant in charge and manned by farmers ,fishermen and merchants. Some 133 years later in the early days of World War Two the Irish government in order to protect its neutrality decided that a series of lookout posts would be built around the coast to monitor activity at sea. These posts were manned by soldiers who were called the Coast Watching Service. Today on Doon Hill sits a well preserved Irish military post set in the ruins of a British military post. Doon Hill on approach is very aesthetic, access is either along the foreshore from Bunowen pier or thru a private entrance located at L5995143169 A which seems to be the original entrance to the castle and on to the military constructed tract to the summit. Overlooking Bunowen Castle and the Quay views are fab all around. Linkback: https://mountainviews.ie/summit/5025/comment/19598/
