Fláajökull Glacier is one of several glacier tongues progressing south from Vatnajökull glacier in Iceland. Vatnajökull is the biggest glacier in Iceland, and one of the most extensive in area in Europe. It is found in Vatnajökull National Park in the south-east of the country, and covers more than 8 percent of Iceland. Fláajökull itself has shrunk more than two kilometers over the last hundred years.
Fláajökull is one of the more accessible glaciers in the area, generally approachable all year around. There are several walking trails to enjoy in the area surrounding it and plenty of scope for fishing enthusiasts. Several species of birds can also be observed in the area, along with wild reindeer and herds of seal.
