I really don't suggest going alone but... make sure you have a cell phone ( that's fully charged) a couple of bottles of water, snacks like granola bars, nuts, trail mix ( something not too bulky or heavy). "I" would make sure I had a pocket knife,some matches or a lighter, a waterproof jacket, an extra pair of socks, some gloves, a hat and one of those light fleeze throws ( that fold up to hardly nothing.) On the off chance you get lost, hurt, etc you will have something to eat and be able to keep yourself fairly warm. Also let someone know where you are going, what time your leaving, and what time you expect to be back. If you are going in a state park or something like that, let someone in the park ( park ranger office? the gate where you have to go in?)know the same info.
