Nightswimming in the underwater cave "Stóragjá", close to the eastern shore of the lake "Myvatn". The water in the cave is heated by a nearby hot spring to about 35 degrees Celsius. Travel guides warn people not to swim here because the water is contaminated with bacteria, but when you don't have any open wounds, swimming here is pretty safe. Anyway, I did not get ill after swimming in the cave!

We spent the night near the village of "Reykjalíd".
