October brings a certain chill to the air, and you know what that means for us here in Ottawa-Gatineau: Halloween is officially taking over. From spooky trails to costume parties, our region knows how to celebrate the season right, and I've got the scoop on where to find the best of it.

1. Halloween fun at the museum

I'm thinking of taking the little ones to the Canada Science and Technology Museum for their Halloween activities. You can ride the Pumpkin Express to a patch, pick a pumpkin, and enjoy all the special spooky fun they have set up for families.
