This is a very lovely place. I have been wanting to go for years. When you first go in you have the opportunity to walk through their small museum and learn a bit about the site. A few of the displays were either empty or not working but over all the place was in decent shape. Wear comfortable shoes for walking and maybe take some back up ones in case you stubble in a puddle. (Lesson learned)
I agree with the review that said this is not a place for small children as they would grow bored quite easily.
A way they could make the park even better is if they could clearly mark the trails.
