Last year, I had the chance to visit this attraction on the last day of the season, hence the autumn colours. It must be a cool oasis in the midst of the hot summer! There's been many changes at Bruce's Mill Conservation Area over the years, and my favourite one is the addition of TreeWalk Village. This private attraction is hosted within the conservation, around the buildings where the yearly Maple Syrup Festival is held. (You can access it from the first parking lot to your right.)
As soon as you get out of the car, you can hear laughter coming from the Village. What's not to love! Gorgeous little tree houses that look made out of giant popsicle sticks, adding splashes of colour to the decor, suspended nets linking one to the next, slides for quick exits, plus a Hobbit-like structure in the back. All of this in a beautiful setting of tall trees, throwing a fantastic yellow glow in the fall and offering shelter from the sun in the summer. The TreeWalk Village is managed by TreeTop Trekking, also responsible for the aerial trails nearby (not included with the admission to the Village).
If you walk around the Village, you'll be able to access Bruce's Mill trails. They're not very well marked but try to follow the white or blue markers for a lovely walk through the tall trees, then on a boardwalk, over small bridges, and into a hilly field, which you will reach in less than 20 minutes. (See this photo gallery taken in the fall.)
