The attraction has reached a milestone ahead of last year's target
New figures show the Cliffs of Moher Visitor Experience in Co Clare has recorded one million visitors within a calendar year.
This is the fourth year in a row the numbers have hit one million.
The world-famous visitor attraction reached the figure on Friday, 11 days ahead of when the same figure was reached in 2016.
The attraction is now on course to exceed its record visitor total of 1,427,166 people in 2016.
The Cliffs of Moher Visitor Experience, which is owned by Clare County Council, has seen substantial investment in recent years.
It is also marked as a Signature Point along the Wild Atlantic Way route.
The director of the attraction, Katherine Webster, says measures continue to be put in place to accommodate the increase in numbers.
"These significant visitor numbers are fantastic for the local tourism sector and the wider West of Ireland economy", Ms Webster says.
"However, we continue to deal with the challenges in relation to capacity management and sustainable growth.
"Measures to sustainably manage group tour numbers have been in place for some time while long summer opening hours and advance notice of capacity constraints onsite are provided both online and via advanced digital signage on all approaches to the cliffs.
"The reality is much of the growth has been experienced in low and shoulder season while high season growth comes outside of the peak hours of 10.00am to 5.00pm.
"The increased visitation in the evening drives benefit to accommodation in the local area.
"We also are working with other local tourism providers to encourage visitors to experience more of our wonderful county of Clare than the cliffs alone."
