On day 5 we went to Askja. It must be said here and now that Askja is fearsomely remote. Deep in the interior of Iceland, temperatures average below freezing for 8 months of the year, and what is laughably called the road (it’s a track scraped into the dust) is passable for only 3 months a year. We caught the penultimate tour of the year down there, and made sure that we had packed all our warm clothes. In fact, though, the weather was quite nice. The sun shone brightly, and when we stopped for lunch near Mt. Herðubreið, we had lunch in the sun on a picnic table outside the mountain hut there. After another stop at the side of the river Jökulsá á Fjöllum (the same river which plunges over Dettifoss), we got to Askja at about 2pm.
The first thing to do was explore the caldera. A caldera is formed when a volcano has a huge eruption, and the magma chamber underneath is emptied. The mountain above then crashes into the ground, leaving a huge crater. Askja did this in 1875, expelling enough volcanic material with enough force for some of it to land in Scotland. The volcano collapsed in on itself, leaving a 50 square kilometre crater. The former flanks of the volcano now form a ring of mountains known as the Dyngjufjoll.
The deepest part of the crater is filled with Iceland’s deepest lake, Öskjuvatn. On the day we went, the placidly shimmering reflections of the snow-capped mountains in the still waters of the lake made it hard to believe the destruction behind the beauty. A swim would be tempting but for the near-freezing temperature of the water, and also the fact that two German researchers once disappeared without a trace while out on the lake in a small boat.
More inviting is the lake inside Viti, an explosion crater formed during the most recent eruptions at Askja, in 1961. Not to be confused with the Viti at Krafla, this Viti contains a hot, opaquely blue lake, apparently ideal for swimming. However, you have to negotiate a steep and slippery slope down into the depths of the crater, and even at the top, the smell of sulphur is overwhelming. Even though there were completely naked Swiss girls in there, we gave it a miss.
The weather stayed nice for the first two days at Askja. This brought out the midges, but the magnificent desolation of the beautiful wastelands more than made up for that. A spectacular canyon cut deep in the mountain just behind where we camped, and a hill nearby afforded a stunning view all the way to the volcano Snæfell 40 miles to the east, and Herðubreið 30 miles to the north. Lava from 1961 snaked across the plains, and several ancient craters could be seen. The land for miles around was covered in light, fluffy pumice stones from the 1875 explosion. I took one large piece as a souvenir but it crumbled into dust long before it got anywhere near leaving Iceland.
We spent two days hiking about in the wild mountains, and the place left a profound impression on us. Here, we were as far from civilization as we had ever been. The nearest town, the nearest shops, the nearest help, were a gruelling 6 hour journey in a 4WD vehicle away. Within fifty miles of us, there were probably no more than a few hundred people. Within fifty miles of London, you’d find perhaps 20 million people.
On the second evening, though, the weather took a turn for the worse. Rain fell as the sun went down, getting heavier as the night went on. By one in the morning, half an inch of water had found its way into one of our two tents. By the time the bus passed by at 4pm on the third day, we were not distraught at the prospect of leaving. We passed by Herðubreið, by now enwreathed in cloud, and thanked the Norse gods for the good weather we’d had.
