Geitakarlsvötn are lakes in Skagahreppur in A-Húnavatnssýsla. These are two lakes about 0.4 km² in area and a small stream, Geitakarsá, flows between them. Slightly further south is the lake Þrístikla, which it is not accessible by car. Arctic char and brown trout are in the lakes, all of a similar size. A nice stream flows down from Þristikla to Geitakarlsvötn and it has a considerable number of fish, so it is worth fishing. In the middle of the route to Þrístikla is a small pond that has no name, but in this pond, there are a lot of playful brown trout that are well kept. The size is at most 1 ~ 2 pounds. There is no net fishing in these lakes, although it would probably be beneficial.
