I headed back down. I had some time before the bus down was coming, so I decided to walk from the cable car station to the Roques de Garcia, a lava formation a couple of miles away. It was January, I was a couple of thousand metres above sea level, but still it was hot walking weather in the midday sun. The walk wasn't too exciting but the views back up to the peak of the volcano were impressive. The cone had an obvious bulge on one side, and I could see why geologists think it might collapse next time there's an eruption here.
