It is AWESOME!!!!
Kids loved it and wished we could have spent all day here.......especially after we had spent most of the day at the Science Center (http://talesfromtheroad-mwalno.blogspot.com/2010/04/st-louis-science-center-st-louis-mo.html).
There is a charge for parking, but you can almost always find it for free on the street and THERE IS NO ADMISSION CHARGE!!! There are a bunch of other spots where you can spend, spend, spend (kids rode some kind of roller coaster, merry-go-round, food, souvenirs, etc).
I did buy train tickets for all of us ($5.00 per person for one time around), and the KIDS LOVED RIDING IT. The conductor even let them announce the next stop on the intercom.
There is much to see and do here, and it is easy to walk around (or take the train). You could easily spend an entire day here. One thing to remember is that most of it is outside - so it could be rough on a brutal St Louis summer day, or in the rain/cold.
Beautiful grounds, lots of animals, and a friendly staff make it an excellent destination!!
Total - $30.00 (train tickets for $6)
