In April, South Carolina resident J.R. Kimbler set out on a hike at Congaree National Park with his two children.

Kimbler planned to take his 10-year-old and 6-year-old on a short nature walk, but the family ended up lost in the wilderness with no food, water or supplies.

Sixty hours later, rescuers found the Kimblers, who were dehydrated but otherwise healthy.

The Kimblers' story serves as an example of the importance of packing properly for outdoor excursions of any length. Here are the 10 items never to head into the wilderness without.

It's easy to become dehydrated during a hike, especially if you're hiking in warm weather, so bring plenty of water. You can also pack a water filter or purifying tablets if you'll be near a water source.

2. Nutrition

Hiking requires a lot of energy, so you'll burn calories quickly and will need to refuel. You'll have to carry your food, so pack nourishing, lightweight snacks like granola bars, trail mix, nuts or dried fruit.

3. First-aid kit

Bring along a small first-aid kit even on short hikes. At a minimum, the kit should contain bandages, antiseptic, tape and painkillers like aspirin.

4. Navigation

5. Sun protection

It's easy to burn even on cloudy days, so apply sunscreen before you head outdoors and bring some with you. Also, sunglasses are important, especially if you're hiking in snow or above the treeline.

6. Insulation

Weather can change quickly, especially if you're hiking in the mountains, so dress appropriately and bring rain gear and items you can add for warmth.

7. Illumination

It gets dark in the woods, so pack a light source like a flashlight or a headlamp, as well as some extra batteries.

You may not expect to build a fire, but bring along waterproof matches just in case. If you're hiking in a rain-prone area, pack a chemical fire starter or even some dryer lint to use in case you can only find wet kindling.

9. Pocketknife or multiuse tool

These simple tools can be used for everything from cutting bandages to repairing gear, so pack one just in case.

10. Backpack

You’ll need something to carry all these supplies. Look for a waterproof pack with a hip belt to help support the pack's weight. It's important to find a pack that fits you well and can hold all your supplies, so do your research or visit an outdoors store where employees can help you get properly fitted.
