The engine coughs, then settles—low and steady—while steam coils from a patch of ground like breath in the cold. You step out and the air is scattered with the metallic tang of sulfur; beneath your boots the earth is warm, and a distant river dares you to follow it. This is Hengill country: a braided landscape of black lava, mineral-streaked hills, and geothermal fissures just a short run from Reykjavik. Over two days the trip folds from short, easy hikes to bolder off-road driving, capped by a night in a remote mountain hut where the wind and stars keep the schedule.
