This is a state park you can't afford not to see. Fun for the whole family, members of any age. I go multiple times every year. Don't miss the Winter Hike every January. The Devil's Bathtub is great to see after a good rain. Take your time and see everything. If you can, stay in a cabin and make a weekend out of it. If you can't, it's still a good day trip. Just go, enjoy and respect mother nature.
Pros: free, beautiful, good family activity
Cons: bring your own food, bathrooms not great
