Repulse Bay Beach
Despite its name, Repulse Bay is actually one of the most beautiful beaches in Hong Kong (which at least partially explains the explosion in residential real estate prices here). The development of the suburb is relatively controlled to the area directly surrounding the beach, so views of the lush hills—and the ocean—make it a great spot for escaping the hustle-and-bustle of the city center. A few tips for newcomers: The beach is most busy in the summers, when weather is warm enough for sunbathing, and the neighborhood is actually not accessible by MTR, so you'll want to book a taxi or take one of the city's express public buses (which only take about 15 minutes from Central).
28 Beach Rd., Repulse Bay
If you don't want to spend all your time in the city center of Hong Kong, head to Repulse Bay on the south side of the island. If you really want to feel like you're in a different place entirely, spend an indulgent afternoon at this lounge space at the top of The Pulse shopping center: Japanese baths, private cabanas (you can reserve online), champagne bottles, DJ'd events. Yes, it's a scene, and Miami-esque—and very fun.
