THE operator of the Cliffs of Moher visitor centre saw revenues last year top €10m for the first time.
A subsidiary of Clare County Council, which operates the centre, presented the figures yesterday to the authority.
When the council opened the €31.5m visitor centre in 2007, approximately 927,000 visitors that year generated just over €2m in revenues.
However, an overhaul of the entrance charging regime and strong growth in visitor numbers resulted in revenues increasing more than five-fold to over €10m last year.
A record 1.6 million people - 1.57pc more than in 2018 - visited the Cliffs of Moher last year.
The council meeting heard that only 11pc of those visitors were Irish. Americans constituted the largest group of visitors, some 30pc of the total, while 8pc were German and 6pc French.
Together, visitors from Asia and Australia represented 15pc of the total.
The Cliffs of Moher remain the country's second-most popular visitor attraction behind the Guinness Storehouse, which had 1.7 million visitors last year.
Geraldine Enright, general manager of the Cliffs of Moher Visitor Experience, told council members that the Cliffs of Moher Strategy 2040 indicates that visitor demand already exceeds the capacity of infrastructure at the site.
Ms Enright said the key improvements needed to address current demand included: two kilometres of coastal paths; a waste water treatment facility; the expansion of car parking space; an additional building; and park and ride facilities.
The cliffs take their name from a promontory fort which once stood on Hag's Head, now the site of Moher Tower.
