The Ballinascorney map takes in Ballinascorney wood, Black Hill, Seahan and some surrounding areas. The area was first used for orienteering in 1979 when Setanta Orienteers organised one of the first Leinster Championships. The area was used extensively for a number of years subsequently before Coillte felled large areas of mature forest. The area was re surveyed a number of years ago. It now has limited use as large areas are difficult to run on and is used mainly for training and local events
From Dublin, approach from Oldbawn, Tallaght, towards Bohernabreana, taking the Brittas road to the stone cross.
Orienteering will be sign posted from here.
