I wouldnt call it much of a hiking trail however there are some decent boardwalks to cross and Toogood pond is a nice loop to go around for a short run. Also walking through the trail and than down mainstreet Unionville is a good outing
In fact, this trail now is connected from Bruce Creek (Unionville) to Milne Dam Conservation Park (10 km for a loop walk) by the City. This trail is unshaded, flat. Good for beginner.
Nice escape into a forest trail within the city - it's a paved trail with plenty of turns and bridge crossings over rivers. There are a few forks that take you into neighbourhoods so stay on track.
