It is situated at the rear end of the Hvalfjörður. Since the opening of the tunnel under this fjord, most people bypass the area. However, it is a very beautiful part of the Hvalfjörður with some tall mountains and forests.
The river Botnsá runs from the Hvalvatn lake and after a short distance the water falls down alongside the Hvalfell mountain into a steep canyon. The waterfall can be accessed from a parking area at the end of the road. Well-equipped hikers can view the waterfall from marked paths on the east side of the river Botnsá.
