Galtymore is the highest of the Galty Mountains, or Galtee Mountains, a sandstone and shale mountain range with 24 peaks above , which runs east-west between counties Tipperary and Limerick; Galtymore is the highest point of both counties. The mountain is accessed by hillwalkers via the 3-4 hour Black Road Route, but is also summited as part of the longer 5-6 hour Circuit of Glencushnabinnia, and the at least 10-hour east-to-west crossing of the entire range, called the Galtee Crossing, which is climbed annually in the Galtee Challenge.
