Go to the swan's fenced home, continue west along the small (barely visible) trail. This cache is close to one of the large trees along the path.
Short walk, 20 metres off the paved path. Mild bush wack, might need to push some branches out of the way.
Warning: It has been moved around a lot. I apologize if you can't find it.
New CO note: New container in play, much more camouflaged than the last.
