Cnoc na Mara (Hill of the Sea) is a 100 metre high sea stack located in the South West of County Donegal. It is safe to say this stack represents all that is great about adventure climbing. It's impressive soaring 150m long landward arete provides one of the most rewarding and adventurous rock climbs in Ireland. It is easily an equal to the mighty Old Man of Hoy off the Orkney Islands in the north of Scotland. In this short film Iain Miller paddles from An Port road end and free solos the landward arete of this outstanding sea stack. Since its first ascent in 2008, this sea stacks' summit has been stood on by less then thirty people and has now had its first free solo. http://www.uniqueascent.ie/cnoc_na_mara
