According to research published in the Journal of Travel medicine in March 2018, 66 people have died “on or at the base of the Cliffs of Moher” between 1993 and 2017, a period of 25 years. 18 of the 66 cases of death were international travelers. More people have died at the Cliffs of Moher since then, but exact numbers are not available.
When walking along the cliffs, always stay on the path and be mindful of the terrain, the wind, and your surroundings. Getting close to the edge for a photo op may result in tragedy.
