Lake Hafravatn is just outside
the capital limits, 76 m above sea level. It has an area of 1,02 km².
Its greatest depth is 28 m. The river Seljadalsa enters it from the east
and its discharge is Ulfarsfellsa. It abounds in small lake char and the
occasional much larger brown trout.
Salmon also enters the
lake, but is very rarely caught. On the lake are quite a few holiday houses and the ruins
of a sheep pen, which was used to sort out the sheep up to the seventies.
The distance from the capital is about 14 km.
