Loughrigg is a fell (a hill) in the English Lake District.
It's pronounced "luff-rigg" (unlike the Irish 'lough', although it has the same meaning).
A. Wainwright listed 214 fells in the Lake District in his seven 'Pictorial Guides'. Loughrigg was the first of these I went up. (The Eskdale Harter Fell was the last.)
I've done Loughrigg on three occasions since then.
