This area of the bike path seems to come to a end at a road, but after looking both ways, you can see that it continues just a ways away. Plenty of area to park nearby with only a short distance to walk. If you're taking the bike path, then you'll more than likely go right by the GZ. This cache shouldn't be too difficult to find and add a smiley to your collection.
Again, please make sure you're looking both ways before and after making the find. Safety first!
