When you feel like cruising with your friends and enjoy the breeze then this is something for you! First, we all transfer to Halong Bay, Quang Ninh province. Driving along the Red River Delta with outskirt of Hanoi, Bac Ninh province, the home-land of “Quan Ho folk song” which is one of the World Culture Heritage of Vietnam. Hai Duong province where we will have a short stop for relax at around 10:00 or 10:30. Keeping on driving to Quang Ninh province, we can see the land of coal, the land of sea... We arrive at Bai Chay wharf at midday. Warm welcome by the local crew team and we start enjoying 4 hour boat trip. A delicious seafood lunch will be served when we are completely relaxed on board. We are both having seafood and marveling the splendor of the surroundings. When our lunch time ends, it is the time we walk into the Thien Cung cave (Heaven Palace cave) and Dau Go cave to see thousands of stalactites and stalagmites colored by hundreds of neon lights.
