Mývatn Capital of Northern Lights

Hverfjall has a large, circular explosion crater, about 140 metres deep and with a diameter of 1,000 metres. Hverfjall is one of Iceland's most beautiful and symmetrical explosion craters, besides being one of the largest of its kind in the world. It is considered certain that the crater was created during a volcanic explosion, and its age is estimated to be around 2800 - 2900 years.

Dimmuborgir is an area of randomly strewn lava rocks and cliffs, surrounded by vegetation, such as low bushes and plants. Dimmuborgir is a place of surprises with its myriad forms and images, small caves and towering volcanic rock, pierced by natural apertures.

The most famous of these formations is "The Church", aptly named, as this is a cave, open at both ends and with a dome-like ceiling.

It is not only in summer that Dimmuborgir exerts its charm; a winter visit is also an invigorating experience which must, of course, include popping in to see the Yule Lads (Santas) who have made it their home.

Grjótagjá is a small cave in the Lake Mývatn area, and was a popular bathing place at one time. However, geological activity in the period 1975-1984, caused the temperature of the water in the cave's pool to rise to such a degree that it has not been possible to bathe there since. But one can always dream ... a peep into the waters and a fertile imagination could conjure up visions of taking a dip in this cosy little cave, as was the custom in the past.

Höfði is a rocky promontory which reaches into the waters of Lake Mývatn. The view from here is good, giving a vista of the lake's coves and inlets, besides being an excellent site for bird watching. Kálfastrandarvogur bay laps the shores of Höfði and is famous for its unusual lava formations both off and onshore, and these rocky outcrops, named Klasar and Kálfastrandarstrípar, have done much to earn Kálfastrandarvogur and Höfði their reputation for being among the most beautiful areas around Mývatn.

Skútustaðagígar pseudo craters were formed by gas explosions when boiling lava flowed over the wetlands. The craters are a popular site for birdwatchers and are protected as a natural wetlands conservation area.

Askja is a 50 km2 caldera in the Dyngjufjoll mountains. The mountains emerged in eruptions under an Ice Age glacier cap. Askja itself was formed, for the most part, at the end of the Ice Age in a major ash eruption which caused the roof of the magma chamber at the heart of the central volcano to subside.

Askja is a part of Vatnajökull National Park.

The caldera contains several volcanoes, including Víti (explosive volcanic crater). Water has accumulated in the crater, its temperature is variable - it is around 30°C on average. Víti is a popular bathing site, but if you intend taking a dip, please be aware that the sloping path is very slippery in wet weather.

The road to Askja goes from road 1 to road 901 and onto mountain road F905. Onward to F910 to Drekagil. On this route there are two fords to cross, usually small. From Drekagil goes mountain road F894 (8 km) to the car park at Vikraborgir.
Another option is to go from road 1 to mountain road F88 via Herðubreiðarlindir to Drekagil. On this road ther are fords on the rivers Grafarlandsá and Lindá that need to be crossed. The fords can be difficult or even impassable for small jeeps.

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.

At the foothills of this spectacular volcanic mountain is an expanse of hot springs called Hverir that are known for their changing variety. You may also find a number of fumaroles, mud pools and mud pots that all seem to be boiling with relentless energy. The pass Námaskarð is strategically located at a short distance from the Krafla volcano system as well as other interesting geological spots like Búrfellshraun and the desert Mývatsöræfi.

Námaskarð earns its notoriety chiefly because of its sulphurous mud springs called solfataras and steam springs called fumaroles. Though you will scarcely find any pure water spring in this wonderful geothermal site of Iceland, the beauty of the colorful minerals defies all comparisons. The gigantic size of the mud craters is what makes you go 'wow' at the sight of them.

The other thing that is sure to strike you about Námaskarð is the sheer lack of vegetation. However, if you give a thought to the high temperature range, it does not appear an impossibility altogether. The constant emission of the fumes has made the ground utterly sterile and acidic, unfit to sustain any floras and faunas. You must bear in mind that the fumes can be harmful for humans as well.

Mývatn is the 4th largest lake in Iceland, 37 km2 in area. Its shores are indented with many coves and inlets and its surface is dotted with around 50 small islets and skerries. Midges (Chironomidae) are abundant and the ubiquitous swarms of these tiny flies give the Lake its name.
The lake itself is very shallow, and the rays of the sun reach the lake bed over its entire surface. The ecology of the lake area is extremely diverse and interesting; one important characteristic of Mývatn, being the prolific growth and abundance of freshwater seaweed. On the bed of the lake are great quantities of diatoms, while, nearer the surface, Mývatn's famous arctic char weave their way between aquatic plants and little islets topped with fertile vegetation.

On and around the lake there is a teeming and varied birdlife, and Mývatn is the habitat of many kinds of lake and marsh birds. However, much of Mývatn's fame is due to the fact that, during summer, there are more different species of duck gathered on and around the lake than anywhere else in the world. Mývatn is a legally protected conservation area and appears on the register of internationally important wetlands, along with the Laxá river which flows out of the lake.

Grjótagjá is a small cave in the Lake Mývatn area, and was a popular bathing place at one time.

But one can always dream ... a peep into the waters and a fertile imagination could conjure up visions of taking a dip in this cosy little cave, as was the custom in the past.

Lake Mývatn is a veritable paradise for birdwatchers and there is a highly diverse birdlife to be found both on the waters of the lake itself and on its shores. Many waders and marsh dwellers make their home there, but Mývatn is probably best known for its unique duck species composition. During the summer months there are more species of duck gathered in and around its waters than anywhere else on the planet. Mývatn and its wetlands are protected as a nature reserve (The Mývatn-Laxá Nature Conservation Area). It is registered as one of the internationally important wetlands, along with the Laxá river which flows out of the lake.
