Reynisfjara Beach - This beach is gorgeous and an absolute must-see! With its rare black sand and basalt columns, there is much to explore on this volcanic shoreline. The black sand is lava that cooled once it hit the water, and the sand is more like various small stones. White sand and red sand beaches (Westfjords) also exist in Iceland. While on Reynisfjara, you can see Gardar, which is a basalt cliff that resembles a staircase to heaven. It is a natural pyramid and was formed by columnar jointing. There are many basalt columns throughout Iceland, but this is by far the most exceptional.
