Maps
Topographical maps make it possible to visualize the terrain in a specific region. These maps, along with a compass, also help you navigate the trails. Wearing a watch helps you with pacing, tracking the duration of the hike and timing rest stops.
First Aid Kit
A first aid kit should contain adhesive bandages, gauze pads, antibacterial hand cleanser, antiseptic ointment, a cold pack, cotton swabs, an ace bandage, aspirin, sunscreen and tweezers. Pack EpiPens or other medication to combat allergic reactions. To help prevent insect bites, carry a DEET-based repellent. Pack a high SPF sunscreen as well.
Water &Snacks
To stay hydrated, carry at least two liters of water per day for your hike in a lightweight water bottle that can easily fit into your pack. If you are unsure about water sources available during your hike, carry a filter or chemical tablets to treat any water you drink. Pack snacks such as granola, dried fruit, raisins and nuts to stay nourished. Fresh fruit also provides an additional source of water.
Shoes
Hiking boots should be made of breathable, waterproof material with solid traction on the bottom. For longer hikes, wear thick absorbent wool or wool-blend socks. For shorter hikes or in warmer temperatures, wool or polyester sock liners or backpacking socks work well; be sure to pack an extra pair of socks any time you go hiking. Wear a wide-brimmed hat to shield your face from the sun.
Pants
Hiking pants should be made from quick drying, synthetic material such as nylon, for flexibility, quick drying and wicking action. Pants designed for hiking can usually be converted into shorts for versatility and have extra pockets. Cotton clothing should be avoided. Cotton takes longer to dry and absorbs moisture. Shirts should also be more form-fitting and of synthetic materials, such as Capilene, that are designed to absorb moisture and keep you dry.
Backpacks
Hiking backpacks designed to carry heavy loads distribute the weight of the pack as evenly as possible. For overnight hikes, a backpack with shoulder and waist straps makes a good choice. For shorter hikes, a backpack or fanny pack can be used to carry basic items. For every hike, a whistle, waterproof matches, flashlight, spare batteries and a pocketknife should be carried at all times. For areas prone to bears, you can carry a can of "bear spray" or pepper spray on your belt. Cell phone reception might not be available in all areas but it's still a good idea to carry a phone with you.
