Spend a moment to observe swans and ducks on the water while there. It is a low traffic location.
You are looking for a small well camouflaged container at the end of the footbridge.
It is a small DIY container with log only. BYOP. Tweezers may be useful to remove log (otherwise you should be able to shake it out). Replace cap tight before rehiding. Happy caching!
Congrats to IslePunkFan for being FTF:) only few minutes after posting.
