Here are 12 basic tips for having a warm night’s sleeping while sleeping out on the snow or ice.
1. Pick a sheltered campsite. Camp on the leeward side of ridges and mountains or near large boulders that break the wind. Avoid camping near water or in drainage areas where cold air collects. For me, views take priority, so generally, I don’t always pick the most sheltered site. To stay warm, I rely on other strategies (listed below).
Even if you are an experienced 3-season backpacker, realize that the winter adds unique risks, and what you know about common gear, such as stoves, hydration systems, sleeping bags, sleeping pads, and tents, will be different from what you need to know for winter conditions.
Whenever you hike into the backcountry you expose yourself to dangers and risks, such as avalanches caused by snow, mud, or rock slides. There are hunters, falling rocks, falling trees, tree wells, and the risk of slipping off ledges, falling through snow or ice, suffering from hypothermia, snow blindness, frostbite, severe sunburns, stove accidents, etc.
Know the risks when you decide to go winter backpacking. Be prepared and bring what you need. Basic tips for staying warm and knowing what gear to bring are explained below. This is not a comprehensive discussion of winter backpacking or backcountry safety, but it does contain important things that you MUST know before going.
