The north-east coast of the island of Ko Samet, home to most of the tourist bungalows and restaurants, is often packed. However, you can choose to ignore them and head for the island's most beautiful beach, Hat Sai Kaew (Diamond Beach) and a 5min-walk away to the south, its extension, Ao Hin Khok, a delightful stretch of sand that is most enjoyable at the start of the day.
