Hidden hot spring behind Seljavallalaug in Iceland

Seljavallalaug pool

Most people have heard about the Seljavallalaug pool. Its temperature is lukewarm and some people advise against swimming there because of bacteria/algae in the pool. However if you go a couple hundred meters up the river, you will find a pretty cool makeshift hot pool right next to the river where you can do cold dipping in the glacial river followed by 42C of pleasure.
