The Gate of Hell: Mount Hekla
Hekla Volcano
An easily accessible dead volcanic crater: Mount Whirl.
The volcanic crater of Whalefjord in northeastern Iceland is a dormant volcano. According to archaeologists, the last eruption of this volcano was between 2500 BC and 2800 BC. This means that the volcano has been inactive for over 4500 years. The volcano has two names, Hverfjall and Hverfell, both referring to the same volcano. Its crater has a diameter of only 1 kilometer, making it very easy to climb, taking only about 1 hour to walk around the edge of the crater. From the top of the volcano, you can see Iceland's famous Lake Myvatn and enjoy other beautiful scenery, making it a very worthwhile tourist destination. This dormant volcano crater is located in the northeastern region of Iceland and, although spectacular, it receives relatively few visitors due to its remote location.
The most dangerous volcano: Mount Katla
The Katla volcano in Iceland is one of the most dangerous volcanoes, located beneath the Mýrdalsjökull glacier. Its eruption can trigger terrifying glacial floods, destroying farms and houses. Katla is one of Iceland's largest volcanoes, having erupted 20 times between 930 and 1918, with intervals ranging from 13 to 95 years. The most recent major eruption occurred in 1918. Volcanologists believe it could erupt again with catastrophic consequences. Before the construction of the Iceland Ring Road in 1974, people were afraid to cross the southern plains of Iceland from Katla due to frequent glacial and river activity. It is very difficult to reach the Katla volcano, with only the option of hiking or taking a helicopter. The Katla volcano can be seen along the Fimmvörðuháls route from Skógafoss waterfall to the Þórsmörk valley.
