Hot Springs
Seltún
The volatile geothermal field Austurengjar, about 2km south of Kleifarvatn, is often called Krýsuvík after the nearby abandoned farm. At Seltún, the main sight, boardwalks meander round a cluster of seething hot springs. The mud pots and steaming sulphuric solfataras (volcanic vents) shimmer with rainbow colours from the minerals in the earth.
