Stay clean! Packing the basic toiletries is a simple and very necessary step in the packing process. A traveler should always carry a bag with soap, shampoo/conditioner, a toothbrush, toothpaste, deodorant and a comb. These items come in handy when your hotel is not five star, your tent does not have any, or you end up stuck at the airport overnight.
Be Swiss Army ready. A pocket knife is an essential tool in every outdoor enthusiast's belt. Its multi-purpose design and small size makes it useful in almost every situation from emergencies (cutting bandages, sharpening sticks), to cooking (opening cans, preparing food), to grooming (clipping nails, tweezing eyebrows). Airplane travelers must pack this item in a checked bag to pass security.
Take care of your feet and they will take care of you. One of the most important things to pack for a trip is a pair of shoes that is comfortable, breathable and supportive. Whether you are trekking through a jungle or over ancient cobblestones, your feet need to be protected. Before your trip visit your local outdoor retailer and try on several pair of walking shoes and sandals. Find the fit that is right for you and make your selection a packing priority.
Be prepared! No matter where you are traveling, it is always a good idea to carry a first aid kit that contains at least these essentials: Band-Aids, gauze, tape, scissors, Neosporin, tweezers, sun block, Ibuprofen or Tylenol, bug spray and antibacterial sanitizer.
Channel your inner Ansel Adams. It might sound like a big "duh" but don't forget your camera. Even before your favorite pair of jeans, you want to pack your camera. The images from your trip and the memories they trigger are irreplaceable.
Pack it all in. No traveler should go without a good backpack to carry stuff in. A good-sized pack can fit all the essentials and be comfortably carried wherever you need to go.
