Continue your paddle upriver past the #416. Here the river starts to narrow and shallow, so the water is starting to move a little faster. Take care approaching the riffles upstream from here!
You will need water transportation to reach the cache once at the GZ, which is reachable from your watercraft.
This cache will take you to a put-in on Cedarview Road, just southwest of Ottawa, where you'll find parking at the side of the road, and a launch for your cartop boat.
Watch for painted, and snapping turtles sunning themselves on logs, and green herons perched on trees on the way to the GZ.
FREE canoe and kayak (Rooftop boats only) launch and parking at N 45° 15.116 W 75° 45.868.
