Armação dos Búzios, Brazil

With a population of 42,527, Armação dos Búzios is no quaint fishing village. This once-sleepy retreat for Rio's elite has blossomed into an international tourist hub, complete with all the headaches that come with rapid development. The town's 23 beaches are a major draw, but the east-facing shores can be wild and unforgiving, attracting surfers more than casual swimmers. And while the mild, tropical climate is pleasant for much of the year, the rainy season from November to March brings a persistent bureaucratic headache as the influx of visitors overwhelms the city's infrastructure. Armação dos Búzios may offer an escape from the chaos of Rio, but those seeking a truly relaxing beach getaway would be wise to look elsewhere.
