there are some wonderful state parks in which you can go camping and hiking in. The link I put in is the website for all the state parks in PA. Hope you and your friends have fun. Just a few tips...make sure one of you has a cell phone(with good battery life/charge) and that phone gets reception wherever you go. 2. Don't eat anything you see out in the woods. Loads of poisonus stuff. 3 Wear warm clothes because the nights are chilly/cold.
