As you drive east from Reykjahlíð toward the Krafla Geothermal Area, you’ll encounter a striking turquoise lake, blemished by industrial pipes and bright yellow and red warning signs. As inviting as it may seem, the steaming blue water here is strictly not for bathing. The site is a small geothermal station providing power for the local region and water for the nearby Jarðböðin Nature Baths.
