South Marco Beach is very average compared to Tigertail Beach and others in Naples, too. It isn't as spacious and very crowded, besides it's so covered in shell particles and things that it finds a way to wedge itself in your shoes. Look closely into the distance you'll see sea birds and possible even dolphins! This beach has very great shelling, but swimming here isn't nearly as glorious. In the end, this beach is mostly just a nice place to relax and go shelling or enjoy the wildlife.
