In Hvalfjörður near Hvammsvík is a small but cozy hot tub. The tub is made out of rocks glued together with concrete. The water in the tub comes from a well nearby. And is lead to the tub by a hose. You can control the tempter in the tub by putting the hose in or taking it out. The tub and its surrounding is nice and fairly clean. The actual name of the tub is not known.
