Ages 0-12 : Free Ages 13 - 64 : $14.00 There must be a discount for senior citizens, but I cannot find info on that.
The annual pass is the best deal. Works at the many gardens across the country!
Also it's free on Wednesdays!
I think the senior discount is a couple of dollars. There is also a $5 fee for the tram if you take the tour. They only take credit cards to ride it.
