A quiet day at the beach gets an adventurous start when you board a tram and careen down a ¾-mile boardwalk through shaded mangroves and a network of canals. At the end is a pretty, secluded patch of sand that still has notable activities because of the family-vacation-magnet Waldorf Astoria Naples just a few steps from the public parking lot. The surf is calm, perfect for swimming, and aside from the usual lying out, shelling, and sand-castle building, you can spring
for a kayak and meander around the marsh for a different kind of water experience. Amenities: food and drink; showers; toilets; water sports; parking (fee). Best for: solitude; swimming.
