There are bamboo bridges for tourists to walk around the island. Tourists have to buy tickets from Cau Da Port in Nha Trang.
A one-day tour to the island costs VND350,000 (US$16) a person and tourists will be served breakfast, lunch, drinks and fruits. All tourists have to leave by nightfall.
Different sea currents make the water cool on one side and warm on the other.
