How long does it take to go thru it

It depends, your can pull over and take pics, there is an area by the birds that you can get out of your car. There is another area where you can get out, walk some trails, see the wolves, bears, eagles etc. And a petting zoo (which was closed for petting) A place to get something to eat. The gift shop at the end. All in All it took us about 3 1/2-4 hours from start to finish.

1.5 to 2 hrs or more if you do walking. There is a restroom there too. It's very interesting and fun!
