East of the town, half way to Lake Mývatn, is the beautiful waterfall Goðafoss (Fall of the Gods).
------------------------------------
One of the absolute most popular tourist destinations in Iceland is Lake Mývatn and the Krafla area. The landscape in the area is varied to say the least. The lake itself (Mývatn - Lake of Midges) is famous for its rich birdlife and its not so popular midges. The midges can be a real pain so be prepared!
The Skútustadir pseudo-craters in the south is a place to visit. These green craters are only "fake craters". Dimmuborgir is another area of interest, this is a big labyrint of lava sculptures. Follow the paths so you don't get lost!
The whole area is highly geothermal which can best be seen at Hverarond with its sulphur pits and bubbling mud. Definately one of the most exciting geothermal areas in Iceland. At Krafla you can see lava from the Krafla eruption in 1984. Here is also the deep-blue explosion crater Víti.

The National Park Jökulsárgljúfur is definately one of the most exiting and spectacular parts of iceland. Jökulsárgljúfur (Glacier-river-canyon) is a gigantic canyon which has been shaped by the river Jökulsá á Fjöllum. The river has created an amazing landscape with powerful waterfalls and peculiar sculptures carving its way through stones and rocks.
In the northern part of the park is a popular camping spot called Ásbyrgi. It's a horse shoe shaped canyon told to have been created by one of the horses of the ancient nordic Gods. Hjódaklettar (Ecco-cliffs) is another interesting place. It's a number of huge cliffs with strange acoustics.
The most famous sight in the park is the massive waterfall Dettifoss. It is not one of the higher waterfalls in Iceland (45m), but it's by far the most powerful, and actually the most powerful in Europe. Close by are two other beautiful waterfalls, Selfoss and Hafragilsfoss.

Húsavík (pop. 2500) is often called "the whale watching capital of Europe" and this is why so many people visit this place every year. The whale watching industry has been growing rapidly and there are now operators in all parts of Iceland. In Húsavik there are two whale watching companies with departures a couple of times every day. The church in Húsavík is said to be the most beautiful building in Iceland.
