In the valley Jökuldalur (Glacier Valley) in East Iceland there is a marvellous natural site that almost nobody knew about until recently. For a long time it was hidden under water or until the hydroelectric plant Kárahnjúkavirkjun was built and the waterflow in the glacier river Jökulsá á Dal, a.k.a. Jökla, was extremely reduced. This marvel is the part of Jökla's canyon which is called Stuðlagil Canyon. Stuðlagil Canyon has one of the biggest and most beautiful basalt columns formation in Iceland.
There are two options to access Stuðlagil Canyon. To access the canyon from the west site you turn south on the Ring Road nr. 1 to road nr. 923. Then you drive about 19 kilometers to the farm Grund where you will find a parking lot and a path to riverbank (the walk is about 250 meters, or 5 minutes). There is a good view down to the canyon and the diverse columns look spectacular. Bear in mind that even though the walk is short caution is needed because the path is partly very steep.
