National Geographic collectively dubbed the four white-sand Clifton Beaches the second most beautiful beach in the world. The most popular section is #4, the unofficial playground of the rich and beautiful, at the foot of some of the most expensive real estate in the world with a fleet of yachts anchored off shore. Lots to ogle at this Blue Flag beach even if it the water is too chilly for swimming. Accessible by public transportation, it's a bit of a hike to the beach, including some steep stairs, but the popular beach bar La Med is nearby with DJs on deck after sunset during the summer months.
