This lake is gorgeous in every season: serene and frozen in winter, a beautiful blue surrounded by green in summer.

The lake is part of the Slattumsrøa Nature Reserve, with inflow from Lusevasan in the north and outflow to Steinbruvannet in the south. A lit trail runs along the eastern side, providing easy access from Skytta in the north and Steinbruvannet and Grorud in the south.
