Krafla’s most impressive, and potentially most dangerous, attraction is the ³¢±ð¾±°ù³ó²ÔÂáú°ì³Ü°ù crater and its solfataras, which originally appeared in 1727, starting out as a lava fountain and spouting molten material for two years before subsiding.
A well-defined track leads northwest to ³¢±ð¾±°ù³ó²ÔÂáú°ì³Ü°ù from the Krafla parking area (which has toilets); with all the volcanic activity, high temperatures, bubbling mudpots and steaming vents, it's best not to stray from the marked paths.
In 1975 the Krafla Fires began with a small lava eruption by ³¢±ð¾±°ù³ó²ÔÂáú°ì³Ü°ù, and after nine years of on-and-off action ³¢±ð¾±°ù³ó²ÔÂáú°ì³Ü°ù became the ominous-looking, sulphur-encrusted mudhole that tourists love today. The earth’s crust here is extremely thin and in places the ground is ferociously hot.
