We were there about an hour. It is beautiful.
I agree with a couple hours. They have some live demonstrations which are interesting and also short hikes. Call to get schedule of demonstrations.
Depends on you. You can walk to the VC from the parking lot and look at the exhibits in an hour. If you want to thoroughly explore the site and examine the the outside e hibits, allow yourself 2-3 hours at least.
Thank you
Only an hour or two
