A hut-to-hut trek in Iceland involves a trail through the empty interior of the island where there are no permanent settlements but there are dedicated hikers’ huts to spend the night. The huts along the trails are basic with beds, camping areas and WC facilities. Some have small shops to stock up on supplies, some have outdoor grills or communal kitchens for cooking, and some have hot showers, but others are very basic and just offer a place to lay your head and unroll your sleeping bag at the end of a day of hiking.
