Navigation
A map of the area where you are traveling and a compass are key items on your supply list. Use the map to familiarize yourself with the area ahead of time so you know what to expect in the area's terrain and wildlife. If you get lost, a map and compass can aid in finding your way out of the wilderness and you can determine how far you have to travel to safety. Maps show water sources, and a working compass means you can orient yourself to the map. A handheld GPS makes navigation even more efficient and accurate, and a cell phone, if service is available, is indispensable.
First-Aid
Fill a plastic watertight bag or container with first-aid supplies. Include an extra supply of any prescription medications you take regularly. Your first-aid kit should contain at a minimum bandages, moleskin, elastic bandages, wound pads, gauze and first aid tape. Pack antiseptic, painkillers, packaged electrolytes, sunscreen, bug spray, antihistamines and anti-diarrhea medication. Include first aid tools such as tweezers and a razor blade. If you are carrying a multi-purpose knife, many include tweezers and a cutting instrument.
Gear
Important survival gear includes fire-starting material, paraffin candles, whistle, tarp or poncho, signal mirror, polyester blanket, waterproof matches, rope, fishing line and hooks, vessel to boil water, canteen and water-purification tablets. Also include a flashlight, extra socks and gloves, plastic trash bag, pepper spray and a multi-purpose knife. Be prepared to make a shelter, fire, and a means to catch food and boil water, as well as signal for rescue.
Food/Water
Water is all-important; carry a canteen or bottled water when you head into the wilderness. Bring nuts, dried fruit, trail mix, hard candy and candy bars; these are small, easy-to-pack items that won't spoil. Knowing the area's plant life can keep you from starving if you do become lost. Pack a small guidebook that describes wild edible plants in the region you are venturing.
