Jim Ryan's 2006 book on the Reeks, Carrauntoohil and MacGillycuddy's Reeks: A Walking Guide to Ireland's Highest Mountains, stated that there were 25,000 annual visitors to the Reeks. The 2013 MAP report quoted Ryan's figures, which were cited in the MAP's Terms of Reference, but stated that: The Reeks are accessed by at least 25,000 recreational users per annum. It is highly likely that the numbers are a factor of 4 times higher based on observation of the year-round level of usage - but data is required to ascertain the visitor numbers. It was estimated that 125,000 visitors entered the range in 2017 from footfall at three main access points, and that 140,000 entered in 2018 by recording footfall at four main access points.
