Rising above the Inishowen Peninsula between Buncrana and Muff, this 397-metre Tump offers a classic Donegal moorland experience. Its rounded, heathery slopes provide a straightforward ascent, rewarded by clear views across the waters of Lough Swilly to the west and the massive profile of Scalp Mountain to the south.

• •The name derives from the Irish Cnoc Glas, which translates as 'Green Hill,' likely referring to the grassy grazing found on its slopes in contrast to the darker heather of the neighbouring peaks.
• •Its position on the southern end of the Inishowen Peninsula provides a panoramic cross-section of the region, with the Derryveagh Mountains visible to the west and the hills of County Londonderry across Lough Foyle to the east.
• •The hill serves as a quieter northern neighbor to Scalp Mountain; walkers often traverse the high ground between the two to take in the full scale of the landscape between Buncrana and the Foyle.
• •While its status as a Tump is a point of interest for list-checkers, the summit’s main appeal is its relative isolation compared to the more popular trails further north in the Urris Hills.
