I finally stopped at the Swan Preserve in Canton, right near the Canton/Granby/Simsbury border.
I have been passing by this little area each time I have driven out to Burlington to explore the Tunxis, and I kept thinking "... one of these days, I'll see how close these trails get to McLean's West Ledge Trail".
The map at the Kiosk, as well as the online available information, showed Red, Yellow and Blue Trails, with a bit of a possible extended trail to the west. This would be the one I hoped would get me close to West Ledge.
