The guide leads the minivan out of Reykjavík and the landscape changes from suburban streets to black, lichen-dusted lava fields. Wind pushes across the low ridges, and the entrance to Raufarhólshellir yawns like a dark seam in the earth — a cool, quiet place where the air smells faintly mineral and the headlamp beam slices through centuries of solidified flow.

Dress in layers
