Loughsalt Mountain [Cnoc an Liathain]

Rising steeply above the deep waters of its namesake lake, this Donegal Marilyn offers a rugged, heather-clad ascent. The summit provides a grandstand view across the Fanad Peninsula to the Atlantic, with the distinctive flat-topped silhouette of Muckish Mountain dominating the western horizon across the waters of Sheep Haven Bay.

• •The Irish name Cnoc an Liathain translates as 'Hill of the Grey One,' likely referring to the weathered quartzite outcrops or the pale lichen found near the summit. The English name Loughsalt is a corruption of Loch Alt, meaning 'Lake of the Cliff.'
• •The mountain overlooks Lough Salt, a deep glacial lake sitting in a hollow at its base. Reaching depths of over 60 metres, the lough is a significant local landmark and serves as a primary water source for the Letterkenny area.
• •From the summit, the northern view is exceptionally clear, taking in the sandy tracts of Rosapenna and the remote, jagged profile of Tory Island on the distant Atlantic horizon.
• •The hill is primarily composed of metamorphic quartzite, which gives the summit a pale, shimmering appearance in direct sunlight, contrasting sharply with the dark, peaty moorland of the surrounding Donegal highlands.
• •Despite the name, there is no need to bring a surfboard; the 'salt' in the title is a linguistic remnant, and the water at the bottom is strictly freshwater.
