Camping requires a lot of energy. All that fresh air makes for some tired campers at the end of the day. So, you want to make sure that all of your nature enthusiasts have the right fuel.
The best snacks to bring along are ones that will provide energy, as opposed to sugary sweets and drinks that inevitably result in a crash. Stock up on nuts, fresh and dried fruit, granola bars, peanut butter and jelly (or honey) sandwiches and of course trail mix. Hydration is also important, so bring along plenty of drinks, such as fruit juice or water. Make sure everyone has their own reusable bottle for beverages to cut down on waste; it's also a good way to monitor everybody's liquid intake.
