While ideally you'd be biking here to go mountain biking in McLaren Park, if you must drive to get here, this is the highest trailhead parking in the park. From here trails go in all directions: An interesting climb goes a bit higher to the Blue Water Tower, with the main trails of the park obviously downhill to the south and east from this point. To circle McLaren Park on upaved MTB trails, you can go clockwise or anti-clockwise from here.
