The only control they have is a paddle.
You don't need to leave the city if you are in the mood to catch some sun in Nha Trang. A long, palm-lined stretch of soft white sand lapped by turquoise waters runs along the east side of town. All you need to bring is a bathing suit and sunscreen; everything else, including pillows, towels, beach chairs and umbrellas, can be rented. Small restaurants along the beach serve inexpensive food and icy cold beers. If you need to retreat to some air-conditioning, a number of resorts along the beach have blissfully cool restaurants.
