I have to admit, I never was on a volcano before. Thus, I was astonished, when I saw these structures and colors first.
The greens are tiny plants: lichen and moss. Although the green is so intense and seems wrong, it is real. The reds come from the minerals in the ashes. All these photos are taken around the volcano Hekla, the snowy mountain you can see in one of the photos in the background.
You can even drive uphill to one of the side crates and have a look inside the eruption crack. But, don’t ask for streets. You need a four-wheeled off-road vehicle to drive here. In on of my next posts you can see, how roads on Iceland look like. Also, be prepared to cross rivers with your car. Driving in the highlands isn’t easy and I was gland to have an experienced driver along.
