I heard about this place last year when I took my caravan to the Norfolk coast. What I didn't know is that it is that this place is based on the book, BeWilderwood. You don't need to have read the book to enjoy this place but after having read the book, it brings it all together.
This place is basically a huge climbing park. It has something for all ages. We did crafts, saw a show and rode a boat. I recommend to make time for everything and let your inner child loose.
They have places that sell food. But i always pack a lunch. So if you are coming here with two adults, I would suggest leaving your lunch in the car as its not too big to collect it when you are ready to save carrying it arround.
