The pavilion site is accessed from Springbank at 681 Blair Road. You can check it out on google maps (however, the location is a bit farther east along Blair Road than shown). Look for a sign for "Springbank", a stone house and a gravel parking lot to the south of the Blair Road. Park, and walk up the cart track at the left edge of the lot, which winds behind the stone house, and up past the community gardens to the pavilion site.
Here is a location map that will help you find your way to the pavilion site. (It is the wee rectangle marked "proposed education pavilion".)
