Longyearbyen is tiny and easily navigated on foot. Note that bad weather and risk of avalanches can close roads; seek info from your hotel before venturing out. Beyond town, snowmobiles are the most common mode of transport; you can drive one if you have a car or motorbike licence, and the technique is fairly simple after guidance. On any excursion, your tour operator will provide an armed guide, in case of polarbear encounters. You’ll find an extensive safety brochure at sysselmannen.no for official advice on trips in and out of town.
