Phuket's famous beaches are on the west coast; Rawai faces east and south, and it is a very different place. Longtails and speedboats bob offshore, boatmen wait on the pier for island customers, and the promenade is a place where locals fish, walk and eat. It is not a beach for swimming: the water is shallow, boats are moored offshore and low tide exposes mudflats and rocks. For a swim, Nai Harn is about 4 km west.
What Rawai does well is food. The seafood market runs along Wiset Road just past the pier: you choose fish, prawns, crab or squid at the stalls, agree the price per kilo, then carry your bag across the road to a restaurant that cooks it for a fee. A Chao Leh (sea gypsy) community also lives near the pier, which gives the seafront its working, lived-in character.
