here we go you need to complete Rescue From Paradise quest or have the young at heart perk. you may also need to have good dialogue/speech/persuasion skills, and/or to have rescued Penny from the slavers. a good science/hacking ability is a plus too. if you've got good dialogue/speech points, you can talk the "mayor" of little lamplight to tell you how to get there. basically, its called murder pass, and it's a maze full of super mutants. pain in the ass, but good for exp. if you have a high science level, and have rescued penny from paradise falls, you can get them to show you a terminal that you can hack, in order to get a safer route there. hope that helps
