Víti is the largest explosive in Askja. The crater is at the northern end of the water, and there is a thin bridge between him and Askja. The crater is about 60 meters deep and 300 meters in diameter. The surrounding crater is a vikar, about 12 m high. Víti was formed in Öskugoset in 1875 and probably in a vapor explosion.

In the eruption of 1875, ashes and weeks were spun in one of the largest ash clouds in the country's history. The volcanic eruption of the eruption was badly built in East Iceland, causing many to move to America.

The estimated amount of ash in this eruption is 2-2.5 square kilometers, of which 0.8 square kilometers have fallen in Iceland. But the ashes of the gosi reached Stockholm for 38 hours, and since then it was possible to paint the ashes. Víti and Askja belong to a sprung system, which is one of the longest and most effective systems of the country. But it extends from Dyngjujökull to Askja and through Jökulsá á Fjöllum and down to sea. It is called the ASOS system and has erupted at least 50 times in modern times. The main eruptions are then the Goshrinan from 1984-1985. Some volcanic eruptions 1921-1930 and last gauges in 1961. It is therefore possible to see major traces of fire in this area. American astronauts came to land in this area to practice the moon journey up to 1960. They came because this area was less like the landscape of the moon. With them in charge, geologist Sigurður Þórarinsson, he was the main teacher of the group. They mostly learned about craters, eruptions, and earthenware.

Many tourists visit Víti annually, but the route is long and turf. There is a lot of cool visibility when it comes to this place. But around there are mountain lakes like Kverkfjöll and Herðubreið. The Dyngjufjöll rises against the crater. Thorvald Thoroddsen stated that here nature is all terrifying and more magnificent than in some other place in Iceland and the one who once stood on the verge of the earthquake never forgets.

The most popular point of interest for tourists is doubtless Víti. Because there you can bathe. But the water in the crater is sulfuric and reaches about eight meters deep. The water is wrong, 20 ° C-60 ° C. Excessive heat may be in the mud of the East Bank, which can be dangerous. What can also be dangerous is that there is a sulfur in the water. Sulfuric vapor then enters the water surface and it has caused people to fall into fainting. Many tourists come to Víti every year and go to a bath, but there are no changing rooms. Therefore, most are naked who go there above and it is a great treat for tourists.
