The views on both sides of this cache are worth the swim! I want to take you to this cache so you can see views that do not make the post cards and will make your photo memories even better should you you bring a camera -highly suggested. The cache is a plastic tupperware like square box, wrapped in plastic. Log book, pen, and standard fun goodies inside. I do suggest watershoes for your short hike. I personally did the back stroke with my GPS and supplies wrapped in 2 plastic bags and swam with it on my chest. It was a light easy swim. Yes muggles saw me, but it looked like a bagged lunch. And that is a good idea too!
