Called "the Avenue" by Palm Beachers, this half-mile-long street is synonymous with exclusive shopping. Nostalgia lovers recall an era when faces or names served as charge cards, purchases were delivered home before customers returned from lunch, and bills were sent directly to private accountants. Times have changed, but a stroll amid the Spanish-accented buildings, many designed by Addison Mizner, offers a tantalizing taste of the island's ongoing commitment to elegant consumerism. Explore the labyrinth of nine pedestrian "vias" off of each side that wind past boutiques, tiny plazas, bubbling fountains, and bougainvillea-festooned balconies; this is where the smaller, unique shops are. The Worth Avenue Association holds historic walking tours on Wednesdays at 11 am during "season" (after Thanksgiving to late April). The $10 fee benefits local non-profit organizations.
