About Mount Leinster#

Mount Leinster is a 20th-century name for the prominent peak in the Blackstairs Mountains on the border of County Carlow and County Wexford in southeast Ireland, rising to roughly 795 metres. It is one of the higher peaks in the region and a visible landmark across much of Leinster.

Hikers use a network of trails that approach the summit from several directions; the ridge and slopes are popular for day walks and hill running. The summit area includes a prominent broadcasting mast and offers broad views across the surrounding lowlands and other Blackstairs peaks.

The mountain has long been part of local land use and upland commons; modern infrastructure such as the mast and marked walkways were installed in the 20th century. The peak has no major built monuments but has been used for recreational walking for decades.

Mount Leinster sits on the Carlow-Wexford county boundary in southeast Ireland, forming part of the Blackstairs range. It overlooks agricultural lowlands to the east and west and is accessible from nearby towns and country lanes.

  • Elevation: rises to about 795 metres above sea level
  • Summit features: marked by a broadcasting mast near the summit and used by walkers for upland routes across the Blackstairs
