The basalt columns at Reynisfjara beach
Reynisfjara beach is perhaps one of our most popular attractions, and for good reason. It not only has the black sand beaches that Iceland is so famous for. It also features basalt rock formations with some pretty spectacular terrain and sweeping panoramic views.

Also asked, why does basalt form columns?

When objects contract, they often crack or fracture. The fracture pattern that forms at the cooling surface will tend to be propagated down the lava as it cools, forming long, geometric columns. Thus, as lava cools to form basalt, it may crack in a hexagonal (or other) shape and form columns.

Also, how do you get to Basalt Canyon Iceland?

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).

Is Iceland made of basalt?

Since Iceland consists for 90% of basalt, let's talk about this rock type first. Basalt is a dark grey or black rock, sometimes having a columnar structure, formed by solidification of magma. It can be dense or fine-grained and usually consists of plagioclase, augite and magnetite. Basalt is not unique to Iceland.

Why is the beach black in Iceland?

Black Sand Beach on South Coast of Iceland. This sand originated from the basalt lava that covers much of the area. Because black sand isn't routinely replenished like most beach sand when storms and tides wash the sand away, black sand beaches tend not to endure very long.
