Entrance is free, parking isn't but not expensive. I went because i read s recommendations from a fb group, my kids are 6 and a spit to 3 and were not that into climbing in and out of the trucks. There are signs to explain what your looking at,the place is clean and there is a small playground (slide, merry-go-round and horse that goes back and forthl). The place is located in an industrial area,not much places to eat.happy surprise no selling snacks or other wasteful junk there. There are bathrooms and lovely places to sit and have a snack. Not suitable for when it rains, all exhibition is outside .
