Visitor numbers at the Cliffs of Moher Visitor Experience in Co. Clare were up 15.8% during 2015.
Some 1,251,574 people visited the world-famous tourist attraction last year, up from 1,080,501 visitors during the previous year, meaning that the Cliffs of Moher broke the million visitor figure for just the second time ever last year.
It is the fifth successive increase in visitor numbers to the popular attraction.
Fully Independent Travellers (FITs), mainly travelling by car, made up 49% of the total. This represents a 14.6% increase compared to 2014. Groups travelling by coach made up 45.6% of the total and increased by 16.1% on the previous year.
Others including walkers, cyclists and those travelling by public transport made up 5.4% and increased by 16.5% compared to 2014.
"This is the highest number of visitors since records were first kept. It exceeds the previous high point of 2014, which was the first time visitor numbers exceeded the one million,” explained Katherine Webster, Director at the Cliffs of Moher Visitor Experience.
"Information on visitor demographics is still being analysed but indications are that the German and UK markets have grown the most out of our top nationalities with the US and Irish markets growing at a slower pace than in the past. The other nationalities that have seen substantial increases in both volumes and market share are China, Canada, Switzerland and India. Closer to home the Northern Irish market has also grown faster than in recent years," added Webster.
