Hiked up for sunrise, of course, so we set the alarm for 2:45 AM and arrived at the trailhead by 4:30 AM. We moved up the mountain quickly since it was middle of the night, nothing to see but the glow of surrounding headlamps and village lights down in the distance. Reached summit in about an hour and watched the daybreak. Luckily had perfect weather and a colorful sunrise. Coffee and hot chocolate available up there. This is a very popular hike, so lots of people buzzing around but I thought it was cool for the most part because we were all from different parts of the world. Once the day had fully arrived, we made our way around the caldera to see it all. Lots of very hot steam venting out of the volcano. Well on our way down, we passed through a congregation of monkeys hanging around for bananas and other tasty hand outs from hikers. Coming off the mountain several hours before noon made for a great opportunity to head straight for a morning cup of Kopi Luwak, and so we did just that.
