Hveragerði is located in the south of Iceland. It is a strange kind of village built in the midst of intense geothermal activity.
Here, Icelanders grow their vegetables at night in huge fluorescent greenhouses! And tourists go for walks in the surrounding hills in the hope of being able to bathe in the famous natural hot water river.
I first went to Hveragerði in 2010, after the 2008 earthquake that is now immortalised by the Quake 2008 museum which goes back over the disruption to the heavily affected town.
However, it is really the geothermal park that is the local attraction, especially if you are travelling with children, they will be able to admire the wisps of steam that come out of the ground, soak their feet in hot springs and observe the local bread baking in a hole underground.
If you have the time, go on a hike in the hill around here to discover even more geothermal phenomena, it is a really good memory and when I was there the place was a lot less popular. Unfortunately, it being so close de Reykjavik, there are more and more walkers in the area.
