Natural hot springs are little pools of warm water which comes straight from the ground. These natural hot springs can be found all around Iceland and vary in heat. Some are safe for bathing while others are filled with scalding hot water and therefore should never be entered. Some natural hot springs have changing facilities situated close by and a pathway or other means to enter the water safely.
Many geothermal pools are centred around a natural hot spring. The source of the water is the same but Icelanders have built facilities for ease of access and control of the temperatures. Later, other amenities have been added, such as saunas, swim-up bars, and massage facilities.
