Choose bigger camp site close to your place. Reserve your time (you can start from 1-2 nights). Take a tent, sleeping bag and pad, axe, lighter, cooler with food and beverage, water jug, flashlight and you will be fine. You may also want portable butane stove, pot, sort of disposable dishes, knife and fire starter. They usually sold fire wood at the site entrance.
Just start doing that and you can easily figure out what else you want to bring with you.
