After participating in a mountain biking section of the Oak Ridges Trail Adventure this past June, I was compelled to get myself a mountain bike and take to the trails. I asked for a Ghost SE 2920 Mountain Bike for my birthday. What a sweet ride. I love the 29 inch wheels.
Here's a map compiling my online research about mountain bike trails in York Region.

I decided to check out Centennial Park in King Township. It has about 5km of single-track mountain bike trails, categorized into three skill levels: beginner, intermediate, and advanced. It was exhilarating to travel these forest trails by bike! I can see myself getting more into this sport. Here are a few pictures I snapped of Centennial Park (entrance on the east side of Jane, north of 16th sideroad).
There are no park signs on Jane, and there's a long driveway, so the park is easy to miss. Here's the view from the park looking toward Jane St.
