A funicular railway links Capri’s port, Marina Grande, with its mountainside main town, an enticing warren of narrow lanes lined with walled villa gardens. Town life radiates from the Piazetta, a small square that at times is so full of visitors that it’s called the “world’s living room.” From there the old town’s narrow streets lead west to the Giardini di Augusto, the terraced, pine-shaded public gardens that overlook the sea.
