Rattray Marsh Conservation Area

A 94-acre protected natural area — one of the last natural shingle-bar marshes on Lake Ontario — with boardwalk trails through diverse wildlife and plant habitat. Enter from the western side of Jack Darling Memorial Park, where parking is available. Per Credit Valley Conservation (the managing authority): the main boardwalk is wheelchair- and stroller-accessible with rest stations spaced under 200m apart, but a separate loop descending toward the forest and Sheridan Creek involves stairs, so not every trail in the area is accessible.
