Is there a parking lot?

Yes, it is located five minutes away on foot, in front of the Centre Pierre-Charbonneau, at 3000 Viau Street.

Parking costs $14.75 for the day, and your ticket is valid for the three Espace pour la vie parking lots: the one at the Biodôme, the one at the Jardin botanique and the one at the Insectarium. (Note that the price of parking does not include admission to the museums.)
