We got the family package that included the Biodome, Botanical Gardens, the Planetarium, and the funiculaire up the outside of the Olympic Stadium. Tickets are good for up to 30 days.
The pricing is ridiculously stupid. They certainly don't encourage visitors from outside of the province. If you can produce a Quebec health card or driver's licence, the family price is $160. If you come from another province, the price is a whopping $215!
The gardens were beautiful. We probably didn't see half of it because we were trying to do all 4 activities in one day. The Biodome didn't take long to go through. It can be done in under an hour. The planetarium was fascinating. There are two shows. The first is a more artistic show, and the second very educational. They should be presented in the reverse order though. The first would have been better understood if we had seen it last.
