Revenues at the company which operates the Cliffs of Moher visitor centre last year topped €10m for the first time.
That is according to a presentation made to members of Clare County Council on Monday.
A subsidiary of Clare County Council operates the centre and new figures presented to the Council show that revenues have soared at the visitor attraction company in recent years.
The Council opened the €31.5m visitor centre in 2007 when 927,000 visitors generated just over €2m in revenues.
However, an overhaul in the entrance charging regime and a surge in numbers has resulted in the revenues increasing more than five fold to over €10m last year.
Last year, a record 1.6m visitors – an increase of 1.57% on the 2018 figure - attended the attraction, which is the country's most popular natural visitor attraction.
However, only 11% of the visitors to the Cliffs of Moher are Irish.
Figures presented at the meeting show that US visitors make up the largest group at 30% with Germans making up 8% and French accounting for 6% of visitors.
Visitors from Asia/Australia make up 15%.
General Manager at the Cliffs of Moher Visitor Experience, Geraldine Enright told the Council's February meeting that the Cliffs of Moher Strategy 2040 shows that demand exceeds the current infrastructure capacity.
Ms Enright stated that the key pieces of infrastructure required to meet current demand include coastal walk 2km zone; a waste water treatment facility; car-park redevelopment, an additional building and park and ride facilities.
An underpass for pedestrians walking from the Cliffs of Moher car park to access the site under a busy tourist route is also under consideration.
Director of Service with the Council, Leonard Cleary told the meeting that each municipal area in Clare has benefited from the profits generated at the Cliffs of Moher
Chairman of the Cliffs subsidiary and broadcaster, Bobby Kerr told the meeting that "this is a product people in other counties would give their eye teeth for".
Mr Kerr stated that the two challenges for the board are to have a product that is sustainable from an economic and environmental point of view.
Last year, the Council awarded a €400,000 contract to an English based company to draw up a 20 year strategy for the Cliffs of Moher.
The Council has commissioned the work by Haley Sharpe Design Ltd after the local authority admitted that the existing visitor facilities at the Cliffs of Moher "strains to be fit for purpose" and are 'now rather overwhelmed’ during peak times with visitor numbers projected to increase to almost two million by 2025.
