The answer is the popular one-day boat tours to enjoy the beautiful islets. There is a four-hour trip to Thien Cung Grotto, Dau Go Cave, Dinh Huong Islet and Ga Choi Islet and an eight-hour trip to Thien Cung Grotto, Dau Go Cave, Dinh Huong Islet, Ga Choi Islet, Sung Sot Grotto and Titov Beach. There is also a two-day and one-night tour which allows for time to go kayaking and cuttle fishing in the bay at night.

On these routes tourists can contemplate the beauty of many of the areas that have contributed to the recognition of Hạ Long Bay, including two of the largest and most beautiful grottos in the bay: Thien Cung (Celestial Palace) grotto (covering 3,000 square meters) and Sung Sot (Surprise) grotto (covering 10,000 square meters).

Both grottos are divided into three chambers containing ornamental stalactites and stalagmites formed millions of years ago. The Sung Sot grotto is also known as “surprise” grotto because its third chamber suddenly opens to a large, monumental palace with natural works of rocks and stalactites.

Dinh Huong Islet, the icon of the bay that resembles an incense burner made of stone, and the Ga Choi Islet, an islet that looks like two fighting cock facing each other are also part of the tour.

After touring these beautiful spots there is time to relax at the beach of Titov Island, about 13 kilometers from Bai Chay Tourist Wharf.

The island was originally named Cat Nang. However, in 1962 President Ho Chi Minh and Russian astronaut Giecman Titov visited the island and Uncle Ho renamed it after the astronaut to mark the visit and the Vietnamese – Russian friendship.

The island offers sun-bathing on a sandy white beach on one side and a climb up to a watch-tower gazebo at about 100 meters above the sea level for a panoramic view of Halong Bay on the other side.
