Hike to Grjotagja Cave

Grjotagja cave is made of volcanic rock, with a secret hot spring inside. Positioned next to the Mývatn Lake. Back in 1970, this pool had started heating up rapidly, making it impossible to bath but later on, it started to cool down and shortly the temperature is around 122° F. Unfortunatly this spot's water doesn’t stay a constant temperature, and sometimes it can simply be too hot to soak in the water.

But especially during the winter, it’s frequently possible to take a dip.

A few hours’ drive from Reykjavik along poorly-paved roads (which sometimes flood a little), you’ll need to have a vehicle with off-road capabilities. However, you can always travel around and witness the striking beauty of this site.
