Depends where you think this summit is on the map.
Terrain: Heather & lots of it.
This photo was taken by Michéal Mc Parland & fair enough it is not of Finlieve.
The mountain range in the background is the Cooley Mountains with Slieve Foy at the highest part which lies in the South of Ireland. Carlingford Lough can also be seen to the right.
