Absolutely worth that drive!! —from someone who also lives in the generally outside Philly area. We camped at Lyman run state park and had to make the reservations pretty far in advance in order to get a weekend close to a new moon. It’s a short drive from cherry springs so we just drove over in the evening when we were ready to stargaze. We’ve considered going back and have looked at some airbnbs, so know there are some in the area too!
