Askja
Important note: I didn't have the opportunity to visit Askja as I didn't have a 4WD when I was in the area. It's a place I'd really like to explore, and the rating in “My Rating” only reflects my first impression of the site.
Askja is a vast volcanic caldera located in the Icelandic Highlands, in the heart of the Ódáðahraun desert, north of the Vatnajökull glacier. Formed by successive eruptions, it is home to two iconic lakes: Öskjuvatn, the second deepest in Iceland (220 m), and Víti, a geothermal crater with milky, warm water (around 25°C).
For more information on Askja and hiking in the surrounding area, check out the excellent websites smartrippers (in French) or epiciceland (in English).
REMARKS
Accessible only in summer (June to September) with a 4WD vehicle, which is required to cross rough F-roads (such as F910 or F88). Guided super-jeep or bus tours are available from Mývatn or Akureyri.
