River Gljúfurá is just south of Grenivík. It is called Hólsá shortly below the road to Grenivík and this is the best of the fishing. There are good sea char in the river and the fishing season is from July 10th to the end of August. Mostly two-to-three-pound char are caught, and this is an exciting option at a favorable price. Many farms own land near this small river and Grýtubakki I & II own the largest part.
