Aldeyarfoss is one of the most beautiful waterfalls in Iceland. It is twenty metres tall, and plummets into a beautiful blue lagoon (which is not so blue in summer). It is best known for its surrounding geology, as on either side of it are rows of hexagonal basalt columns, features found in few places around the world. These columns are so perfectly formed and symmetrical that they seem to be carved by hand.
Víti is a huge explosion crater, about 300 metres in diameter. The crater was formed during a massive volcanic eruption at the start of the famous Mývatn Fires in 1724. The eruption continued more or less non-stop for 5 years and Víti's bubbling cauldron of mud boiled for more than a century after that. Víti is situated near Krafla and there is a tarmacked road leading up to it from highway 1.
