For many people the idea of heading out into the mountains or forests with the intent of staying out for a number of days sounds ridiculous. For others, the idea sounds like an adventure and they’d like nothing better. The ability to survive in the wilderness requires a bit of knowledge and for most people some specific pieces of gear.
If you are heading out into an area to go backpacking or mountaineering requires a good understanding of the area, terrain, weather patterns, survival equipment and the people you are with. Above all leave home with safety gear and know how to use it. Even if you have been on the trail before, bring a map. This bit of information can help you in the event of an accident or if you are lost for some unknown reason. Make sure you have waterproof matches, an emergency blanket, first aid kit, and a shelter with you suited to the conditions. plenty of food and a way to treat water is also important.
Knowing the weather patterns is also important. If you are from the area and have been watching the weather patterns for years you may think you know better than you do, the micro-climates of the area. Be sure to talk to rangers or others that can give you specifics about what to expect.
For certain know the terrain you are heading into as well as the capabilities of the group. It is easy to get into trouble when you are not prepared physically for the strenuous activity some trips require.
Few people should reasonably consider heading out on a backpacking trip alone, so if you are thinking about it and you are not sure, then it is probably safe to say that you are not one of those people. So, know the people you are with on the trip. Know their strengths and their weaknesses or injuries. Most of all communicate. Check in regularly and be honest with your companions about how you feel and what you think you are capable of doing that day. Be safe, have fun.
