About Cnoc na Saileog [Lackadunna] [Knocknasilloge]
Sitting at the southeastern edge of the Maumturks, this modest Marilyn rises above the Maum Valley. The terrain is characteristic of Connemara, with boggy lower slopes giving way to a more rugged, rocky summit. It offers a quieter perspective on the higher peaks of the range and the sprawling waters of Lough Corrib.

Did You Know?
- •The Irish name Cnoc na Saileog translates to 'Hill of the Sallows' (willows), while the alternative Lackadunna likely derives from Leaca Dhubha, meaning 'dark flagstones' or 'black slopes,' referring to the exposed rock on its flanks.
- •Despite its height of just 346m, it is classified as a Marilyn due to its 240m of prominence, ensuring clear, unobstructed views across the Maum Valley toward the main Maumturk ridge and the Twelve Bens.
- •From the summit, the northern arm of Lough Corrib is clearly visible to the east, along with the many small islands that dot the water near Doon and the Mayo border.
- •The hill is frequently climbed from the south near Gleann Trasna, providing a less technical alternative to the notoriously steep and rocky Maumturks Challenge route found further north.
- •Given the name refers to willows, one might expect a woodland; however, in the wind-scoured Maumturks, a sallow is usually any shrub that has managed to avoid being flattened by the Atlantic gales.
