The Grímsá is one of Iceland’s most beautiful fly fishing rivers and is one of a few Icelandic rivers that has tradition stamped all over it. It was frequented by British lords and generals as early as the late nineteenth century and whilst, as with most of Iceland’s rivers today, it is primarily a grilse river, during those early days the Grímsá was famous for its monsters. Every now and then, the odd monster is still spotted giving vivid memory of the golden days of yester year.
