The Trail Map:- OSI Map Series 25
Carns (or Cairns) Hill is a hidden gem located just a short walk from Sligo Town with views of Sligo Bay, Benbulben and Lough Gill, though these views are mostly obscured by the thick forest. The site consists of two short looped walks through a diverse forest plantation which is rich in biodiversity. The hillside features two large unopened and undisturbed Neolithic cairns and associated caves. They are sited on the highest points of the flat summits where the west cairn stands at 123 metres and the east cairn slightly lower at 112 metres. The Cairn (blue) loop will take you to the edge of the ancient east cairn. The cairn is covered with young trees and scrub – ash, sycamore and hazel, so that you might easily miss it and walk by. The cairn is about 45 meters in diameter and some 10 meters high. It is composed of chunks of quarried limestone, and is most likely kerbed and strewn with quartz.
You can also cross the road – with care – at the entrance and this provides access to Cleveragh Regional Park, which is a looped trail which further extends onto the Garavogue River Walk, which brings you along the Garavogue River into the centre of Sligo Town.
