This is a prolific, three rod sea char river with some brown trout and 10-20 salmons caught during each season. It produces 500 - 600 sea chars in a good summer. There is lodge, heated with gas, on the river. The Angling Society of Keflavik leases the river and sells permits.The Hrolleifsdalur valley stretches to the southeast into the great mountain massif of the peninsula Trollaskagi in the North. In it the last traces of the original woodlands of the district were declared a reserve early in the 20th century. All farms in the valley have been abandoned.
