Grænavatn itself is really nice to look at due to its green and name-giving color. However, way more interesting is the small micro hike to another small geothermal area called Engjahver. This hike is super cool and only a few people know that it exists. We parked our caravan and started the hike. Fields of green and orange moss everywhere. Nature in Iceland can be so beautiful. We kept walking and suddenly saw an Icelandic horse staring at us from the far distance – majestic! We stayed on track, a hill in front of us. At the moment we climbed that hill enough to get a glimpse on what’s behind we saw like 20 horses staring at us as if we had just entered their living room and crashed the horse themed party. One of them started to walk towards us. We are not scared of horses in general, but you never know and we definitely invaded their territory here. The horse kept going and as it reached us, it pushed its head gently against our shoulders, telling us to pet it. The other horses followed their leader and surrounded us asking for love and some of our attention. A moment I would never forget. After a while of cuddling those beautiful animals, we continued the walk until we reached an enormous hole in the surface with steam coming out of it. Everywhere was this liquid stone material. This happens in geothermal areas when chemical processes liquidate the stone and leave it as a grey to slightly blue liquid. While it looks really beautiful, it smells quite awful. We roamed around this place for a bit and then went back to our caravan continuing today’s tour.
