This is a high traffic area and much stealth will be needed to find this cache. I suggest trying it on days when there may not be many beach goers. Early morning or night would be good times as well as days with inclement weather.
If you must try during good beach times you may want to bring a book or paper to read while you sit on one of the two benches and wait for the people to leave.
The cache is one of those metal pill bottles that you put on your keychain. There is no pen or pencil so be sure to bring your own. Roll the log up tight and put it in the lid first then screw it into the bottom. If you try to put it in the bottom first you will not be able to get the top on.
