Crogearraidh Mor [Crogary Mor]
Big Crogary is a 180m hill set in the rolling moorland of central North Uist, just north of Lochmaddy. It feels far bigger than its height suggests, thanks to clear views over Loch nam Madadh and out to the eastern hills.
Gaelic: “big” · Pronunciation: crogearraidh more [crogary mor]
