The oldest multi-cache in Florida!
The marina and condo roads have opened up numerous ways to get to the caches, although all routes will involve hiking after parking your vehicle. (You do not have to cross any fences, although the fences seems to be there just to keep vehicles out.)
The first step is to find the "23 Nails" step one which perches near the river.
A note in a plastic bag is in a plastic container with no need to open the bag or container. Read the coordinates there for the 2nd step.
Then from the first find, travel to the location noted along the water to find "the final cache".
Thanks to all the vistiors' nice comments to this double step cache over the many years!.
This a fairly long walk but scenic to get to, so prepare for a little time to locate it! But you will enjoy the scenery during your trip!
