Eldgja, or "The Fire Fissure”, is 40 km long and
stretches from the glacier Myrdalsjokull to the low mountain Gjatindur and
beyond it further northeast. It is a unique natural phenomenon, which was
created during a tremendous eruption around the year 900. In places it is
600 m wide and very deep.
The lava field's area, created by
this eruption, is close to 700 km˛,
which makes it the largest historical lava field of the country.
There are two main accesses to the fissure,
one from its depression and one from the eastern rim. Both lead to the waterfall
Ofaerufoss, which natural stone arch collapsed in 1993.
The view from the top of the aforementioned Gjatindur is
breathtaking on a fine day. The buses of
Kynnisferdir include The Fire Fissure in their
schedule every day during summer.
