The Glacier Lagoon Jokulsarlon is a part of one of the shortest rivers in Iceland, Jokulsa Breidamerkursandi. It is situated at the south end of Iceland’s largest glacier Vatnajokull between Skaftafell National Park and the town of Hofn.
The river is only 1500 metres and prior to 1950 it was uninterrupted by a lagoon. After 1950 the glacier tongue started to retreat and the lake has gradually increased in area. The surface of the lake is at seal level and sea water flows into the lagoon at high tide. Constant sea erosion causes the river to get shorter and shorter and eventually the erosion and the melting of the glaciers will result in a deep bay forming.
Boat trips are offered on the lake among icebergs and natural ice sculptures. The beauty of the ice is further enhanced by the blue-green color of the ice. Jokulsarlon is situated close to highway number one and is considered one of the greatest natural wonders in Iceland. Two other glacier lakes are situated near Jokulsarlon, Fjallsarlon and Breidararlon.
