A report has shown that 94% of visitors to the Waterford Greenway have rated it as either excellent or good.
The study, which was commissioned by Waterford City and County Council, also shows that 80% of people visiting from outside Waterford paid for accommodation while in the county and almost one-in-five visitors stayed four nights or more.
The Waterford Greenway is Ireland's longest greenway and the 46km off-road cycling and walking trail stretches from Waterford city to Dungarvan.
Since it opened in March of this year, 247,545 people have used it - 105,639 on foot and 141,906 on bikes.
All survey respondents were asked about their spending habits while on the Greenway and of those who did spend, most were spending an average of €28.50.
Waterford City and County Council Chief Executive Michael Walsh said the survey results were very encouraging.
"Developing the Greenway was a significant but a very worthwhile investment that is having a major economic and social impact across our County, not just during the peak tourist months but right throughout the year," he said.
The report features responses from 1,177 Greenway users at four specific points along the off-road trail in August and October of this year, some on weekdays, others at weekends.
