Rattray Marsh sits sheltered between Mississauga and Oakville. With its many viewpoints along tree-bordered walkways, this conservation area attracts young explorers and bird watchers. We accessed it from Jack Darling Park, which added one hour to the whole outing but also found a shorter way to its western entrance off a local street. It took us a good half-hour to stroll along the boardwalk bordering the marsh. It was fun to go up and down the different levels of stairs on the boardwalk (not for strollers!). Make sure to stop the kids from time to time and invite them to listen to, and locate, the many birds. Ornithologists have identified some 277 species here! There's a wide range of wildflowers as well. (There are no washrooms on the premises.)
