Lake Ljósalandsvatn is on the border of Vopnafjarðarhreppur and Skeggjastaðahreppur. It is east of the main road over Sandvíkurheiði and lies 230 m above sea level. The lake is about 0.41 km² in area and rather shallow. From the main road there is a road, accessible to all cars, to Ljósalandsvatn. According to old information on the NAT tour guide, there are a lot of small fish in the lake and there is a great need for net fishing. Now the situation is that the lake has the most consistently sized fish found in the lakes on Sandvíkurheiði. Every summer, 5–7-pound fish, both brown trout and Arctic char, are caught there. The stock therefore seems to have improved, over two decades, thanks to net fishing.
