Wearing brand new shoes on the trail will probably give you blisters and make it a miserable hike. Your pack will also become very important the longer you hike. Both internal and external frame backpacks work very well, and choosing between the two is only based on your personal preference. Make sure your pack is adjustable to fit your height and that the weight of the pack is transferrable to your shoulders or your hips, depending on how the straps on the pack are adjusted. This will ensure the greatest comfort while hiking.
Backpacks come in all shapes and sizes.
Choose a pack that suits your needs. It's roomy and lightweight and will fit both adolescents and adults. When you're getting ready to go, be sure to pack only what you need. Your pack will be heavy enough with just the needed things, so you don't want to add any more. If you aren't in the market for a new backpack, try thrift stores, outlet centers, holiday sales, or perhaps you could borrow from a friend or relative.
