About Killerry Mountain
Rising steeply from the southern shores of Lough Gill, this prominent Sligo hill offers a rugged, often heathery ascent. Despite its modest height, its status as a Marilyn ensures a sense of isolation and command over the landscape, providing exceptional views across the water toward the tabletop plateau of Benbulbin.

Did You Know?
- •The name is a phonetic anglicisation of Cill Oiriadh, referencing an ancient church site nearby, reflecting the deep monastic history common to the shores of the neighbouring Lough Gill.
- •The summit offers a clear, unobstructed sightline north to the 'lake isle' of Innisfree, made famous by W.B. Yeats, which sits just offshore in the waters below.
- •Despite being less than 300 metres high, it qualifies as a Marilyn because it drops at least 150 metres on all sides, making it a surprisingly independent peak for its size.
- •At 961 feet, it is precisely 39 feet short of being a 'proper' mountain, a distinction that matters deeply to map-readers but very little to your legs once you hit the heather.
