Probably worth visiting if you plan to visit the Botanical Gardens (you can save money by buying a combined ticket) or if you have young children. Otherwise, the Biodome is interesting enough if nothing special. It suffers a bit from being situated in the wasteland that is the Olympic Park but is easy to reach by Metro from the city centre. The various climatic zones feature a variety of plants, fish, birds and animals and one can wander through these at leisure for an hour or so. The penguins at the end of the tour were a big hit with the class-room of excited children that appeared while I was there. An interesting side-note is that the building in which the Biodome is situated was the Velodrome for the1976 Olympics.
