Reykjadalur valley is the most popular and arguably the most beautiful hiking area in and around the town of Hveragerði. Hot springs and colourful areas full of geothermal activity entertain along a hiking trail which leads to a hot river. For some of the length of the river the temperature in it is perfect for bathing and that’s a wonderful natural experience.
The hiking trails starts at a parking space just above the town of Hveragerði where there are signs with maps and then it’s marked along the way. Furhter hiking options are ample as one can continue to discover the whole area around mt. Hengill.
