Keep your eyes out for a lot of wildlife - in and out of the water. I am sure plenty of eyes will check you out along the way too. You may want to bring a fishing pole on this short trek, as it's a popular spot for easier catches.
As far as seeking the cache, you should be able to stay on the trails to find this one...till you get close anyway. Also, you can park along the road next to Clark Park.
If you are extremely fortunate, you might just see one of these Wisconsin birds:
Northern Saw-whet Owl -
Source: allaboutbirds.org/
A tiny owl with a catlike face, oversized head, and bright yellow eyes, the Northern Saw-whet Owl is practically bursting with attitude. Where mice and other small mammals are concerned this fierce, silent owl is anything but cute. One of the most common owls in forests across northern North America (and across the U.S. in winter), saw-whets are highly nocturnal and seldom seen.
fact:
- Migrating Northern Saw-whet Owls can cross the Great Lakes or other large bodies of water. In October of 1999, one landed on a fishing vessel 70 miles from shore in the Atlantic Ocean near Montauk, New York.
Also, the idea of eyes watching turns my attention to a verse you may enjoy knowing- "Nothing in all creation is hidden from God's sight." (Hebrews 4:13).
Enjoy the search.
