This place is probably more for kids.
I only enjoyed coming to see the biodome because I have never been to anything quite like it before. For a first experience, it was great to be able to reach out, touch the plants, see the many different animals in their "natural" habitat, and learn a little bit about them. My most favorite part was probably all the photos I was able to take. With no fence or walls, it was pretty intense to see a monkey only 10 feet away from me dangling with her baby in a tree.
For the $25 I spent for the package to see the Biodome and Olympic Tower, these sites maybe held my attention for about 1.5 hours. Too short lived, not enough to look at, and lacking in any kind of interaction exhibits.
A must see if you never been here but please don't expect a whole lot.
