On the first day of your trip to Sanya Phoenix Island, start by arriving at Sanya Phoenix International Airport. From there, you can take a taxi or arrange for a transfer to your hotel on the island. Once you have settled in, head straight to the beautiful beaches that Sanya is famous for. Spend the day relaxing on the soft white sand, swimming in the crystal-clear waters, and soaking up the sun. You can also try out various water sports activities such as snorkeling, jet skiing, or even taking a banana boat ride. In the evening, enjoy a delicious seafood dinner at one of the beachfront restaurants and take a leisurely stroll along the shoreline to end your day.
