A 20-year-old American woman fell 60 feet to her death off cliffs in Glendalough, Co Wicklow on Saturday evening.
Ms Kimberley Ruth Irvine, Willowbrook, Illinois, had been part of a group of 20 young people on a day outing to the ancient monastic village.
They had been walking on the Spink, a pathway which runs across the top of the 1100 feet cliffs on the southern side of the valley.
Ms Irvine and a companion appear to have left the wooden walkway along the dangerous cliff walk and had either been attempting to go down into the valley or had been trying to get a better view of the lake below.
Ms Irvine appears to have fallen at least 60 feet down the cliffs and a woman companion who was with her was also slightly injured when climbing down to assist her.
A young man who was one of the party raised the alarm.
Shortly after 3 p.m. the garda∅ in Wicklow alerted the Glen of Imaal mountain rescue team, which arrived within 20 minutes of the accident.
It had alerted the Irish Coastguard helicopter which had been on exercise in Dublin Bay and it arrived to take the two women to Tallaght hospital where Ms Irvine was pronounced dead on arrival.
Experienced walkers have been concerned at the lack of warning signs in the Spink area which has become very accessible to the public since the erection of a wooden walkway along the ridge.
The track, made of railway sleepers, was put in place to prevent erosion on the path and to make the cliff walk safer.
However, it has drawn casual walkers on to the cliffs where there is only one danger sign and no warning to remain on the path.
The Glen of Imaal mountain rescue team was involved in 43 rescues last year and so far this year has been called out once every 10 days.
A recent study carried out by the Dublin/Wicklow Mountain Rescue Team found that while 95 per cent of people walking in the mountains are Irish, 60/65 per cent of the people they rescue each year are visitors from abroad.
The belief is that because Continentals, in particular, think that Irish mountains are small by European standards, they underestimate the dangers involved, especially the rapid changes possible in weather conditions here and the generally difficult walking conditions.
