I cooked up some lunch on the veranda of the hut. As I ate, the clouds suddenly parted, revealing a couple of hikers heading out across a huge snowy expanse, ringed by mountains. A roar away to my right turned out to be coming from a huge steam plume jetting straight out of the ground. I finished my food, grabbed my pack and headed out.
Hiking across the snow was fairly tough going but I knew the hardest bit of the day was already behind me. I'd climbed 500 metres and now I would drop 500 metres to Álftavatn. The weather was beautiful here, and I was alone on the trail pretty much the whole way. I was in an Icelandic dream but I did not let up my pace for a second. I marched pretty much as fast as I could, somehow fearing that if I slowed down I might not make it to Þórsmörk.
Later the weather turned. I descended into a verdant gorge, and crossed my first river. It was only ankle-deep but bitingly cold, and I walked gingerly for a mile or so afterwards until my feet started to feel again. The cloud was thickening and eventually I could only see the trail and a few feet either side of it. Sometimes in the murk I could hear volcanic springs rumbling and bubbling but I couldn't see anything. It began to rain.
Finally I reached a flat grassy plain where I could see that vehicles sometimes drove. A few minutes more walking brought me to the shores of Álftavatn. I set up camp and then walked along the shore in the midsummer gloom, listening to music. I was a third of the way to the end.
