Ljótipollur is in a crater north-east of Frostastaðavatn. Despite the name, the crater is very beautiful, and the environment is unlike any other. The lake is 570 m above sea level and has an area of 0.45 km². The maximum depth is 14 m, and the average depth is estimated to be around 8 m. Ljótipollur was long considered one of the best fishing lakes of Framvatna, but some people think it is too dull to receive that honor. There is only brown trout in the lake, most of it is about half a pound but the largest reach 5 pounds. The crater edges are steep, about 70-120 m high, and care should be taken when going down to it. It is well worth visiting Ljótipollur and often the fishing is good.
