Palm Beach is separated from the mainland of South Florida by the Lake Worth Lagoon. Expect glitzy estates and sandy beaches, including the famous Palm Beach Municipal Beach. Worth Avenue is lined with high end shops, restaurants and art galleries. Art-lovers should head to the Henry Morrison Flagler Museum, inside the hotel and railroad tycoon’s huge mansion. Forbes reports that Palm Beach has at least 30 billionaires, with the town ranking in the top 30 wealthiest places in the USA.
