The number of hiking trails in Iceland is much greater than covered by this website. The shorter and more local ones are left out for the most part. Tourist information centres all over the country offer brochures covering the local areas in much more detail. Many of the longer trails tempt the hikers to prolong the hike by staying an extra day in one of the many mountain huts just to explore the immediate vicinity.
Remember: Hikers only leave their footprints and only take memories back home!
