I didn't sleep that much, and lay awake for much of the evening, dreading the midnight call. Luckily it wasn't too cold, and when the call came I managed to rouse some enthusiasm. I checked my pack and my headlamp, and put on my warm clothes. We had some jam sandwiches for breakfast, and Roy cooked up some mate de coca. I'd had this traditional Andean drink lots of times already, but despite its supposed stimulant qualities it hadn't really done much for me. But this time it did. I don't know what Roy did differently with this brew, but before long I was feeling absolutely fantastic. The pace seemed easy and my pack seemed light. The skies were incredibly clear, and we saw a couple of bright meteors. The climb was going very well. Johan was climbing strongly as well, but the Peruvians seemed to be struggling. The German was also not looking at all happy, and they all decided to keep on going at a slower pace. Johan, Roy and I headed on up, keeping up a good rate.
Climbing at night was a strange experience. It was quite easy to follow the trail, but the darkness made it impossible to tell how far we'd come or how far we had to go. The summit loomed above us, its silhouette against the stars unchanging. Far below, the lights of Arequipa twinkled. By 3am, the zodiacal light was very bright, and it didn't seem long at all from then until the first hint of dawn appeared. We could see the Peruvians still climbing, a few hundred metres below us, but before it got properly light we saw that they'd given up and were heading back to the campsite. At 5.30am, the sun rose stunningly over the nearby peaks of Chachani.
By now I was feeling less fantastic than I had done, but still pretty good. Johan was beginning to feel the altitude, though. I began to lose track of time, and concentrated only on keeping on plodding up the mountainside. At 7am we realised we were very close to the top, but by then I was seriously feeling the altitude, and we spent 45 minutes covering the last hundred metres to the top. And there we were, just over 5800m above sea level, in the middle of the Andes, standing by the gently steaming crater of El Misti. The countryside was wreathed in mist, which was lit up spectacularly by the morning sun.
Johan was feeling very unwell with the altitude, so he and Roy soon set off down the mountain. I stayed at the top to explore for a bit, and it was an incredible feeling to be alone on top of a huge mountain, so tired from the climb but feeling energised by the daylight. The crater was quite active, with extensive yellow sulphur deposits and lots of volcanic gases gently rising.
At about 9am I decided to head back down the mountain. This involved ploughing down a scree-filled gully, which was so steep that I felt in constant danger of triggering enormous landslides. I had to constantly lean back to keep my balance, and after an hour or so this started altering my perception so that whenever I stood up straight, the horizon seemed to curve upwards. I carried on down in silence, becoming slightly paranoid that I might have got the wrong route, but eventually I saw Roy in the distance. By 11am I was back at the camp, where I found that everyone but Johan and Roy had long gone. We wearily packed up, and then trudged back down the trail. This seemed to take forever, and by the time we reached the road we were exhausted. There we met a group of hikers on their way up, and it turned out Roy was guiding them, so he set off back up the mountain. I hoped he was earning good money, because he had been an excellent guide.
I was possibly more tired by now than I'd ever been before, but also ravenously hungry. Appetites tend to disappear at high altitude, and so all I'd eaten since my jam sandwiches at midnight had been two bananas. By the time I got back to my hostel I was in terrible straits because I couldn't decide whether I was too tired to eat or too hungry to sleep. In the end I fell fast asleep for an hour, then woke up with such a raging hunger that I literally ran out to find food, and ate two full meals.
That evening I looked up at the mountain and could hardly believe I'd been standing on its summit just hours before. I felt like I owned it.
