Iceland offers a wealth of exciting outdoor sports opportunities to visitors - fishing, angling, hiking, camping, kayaking, skiing, mountain biking, golfing and diving, to name but a few - but the great lure for real outdoor enthusiasts must be glacier trekking. There are many excellent, reputable tour companies offering visitors to Iceland the chance to unleash their inner Arctic explorer and experience Iceland's astounding natural bounty hands-on. Your adventure will consist of about seven hours of walking across the snow-blown, translucent landscape by day, before being fed and entertained while camping out on the freezing icefields at night. There are day-long tours available for less extreme personalities, and some tours which combine glacier trekking with plenty of time spent camping next to hot springs. Snæfellsjökull glacier is probably the pick of the explorable terrains.
