I'm not a photographer at all and I only had my phone, so my pictures aren't impressive compared to what you've already seen.
But it was so incredible, the most awe-inspiring thing I've ever seen in my life. It was snowing for a lot of the time, but we could still see the volcano well. The noise is something else, when it spurts lava and it crashes down. It sounds a bit like waves crashing on rocks. You can feel the heat from a long way off, like standing near a big bonfire. We completely lost track of time there, we were just staring at it for so long. We could hardly believe it was actually real and just there.
We parked and started walking at 5 pm, got back to the car at 9 pm by which time it was fully dark. Then it took ages to get through the one-way bit of the road with snow ploughs trying to get through the other way and a few people with jeeps who had been a bit over-ambitious with their off-road parking and needed to be pulled back onto the road. Finally got home at 11 pm and I was bloody knackered. Easily one of the best experiences of my life, though.
