You can't explore Rouge park in one day. It is huge, with the Toronto Zoo occupying only a tenth of its area. It offers a wide variety of natural settings accessible from different points. When I visited with my 3-year-old on a bright fall day, I chose to access the park from the Reesor Road and thought it was the perfect place to enjoy fall colours with a little one. A cascade of leaves would fall from the trees every time the wind blew, and the ground was covered with crisp leaves. The easy trail (off the small parking lot) runs along the very shallow river and, in many places, we had access to it over a wide band of pebbles. We laid out our picnic on a fallen tree by the water. Further on, the trail was narrower and bushier so we turned back. We were only twenty minutes away from the parking lot.
