write a travel guide about natural wonders of vn you know .

There are many natural wonders in Viet Nam like Paradise Cave, Perfume Pagoda, Cuc Phuong National Park,... but I like visiting Ha Long Bay best because of its attractive scenery, picturesque setting and touring experience.
Ha Long Bay is one of seven natural wonders of the world. It's located in the northeast of Viet Nam. In 1994 and 2000. Ha Long Bay was recognized by UNESCO as a World Heritage Site. Administratively, the bay belongs to Ha Long City, Cam Pha town and a part of Van Don District. It has 1969 islands and thousand of limestone karsts in various sizes and shapes, concentrated in 2 main zones: the southeast (belonging to Bai Tu Long Bay) and the southwest (belonging to Ha Long Bay). Many of them were acquired their names as a result of interpretation of their unusual shapes such as Voi Islet, Ga Choi Islet, Mai Nha Islet. At the centre of the islands, there are wonderful caverns such as Thien Cung, Tam Cu, Dau Go, Sung Sot,... Coming here, you can have unforgettable experience with the peaceful nature, blue sky, white sands and tourist facilities as standardized hotels, restaurants,... Ha Long Bay is famous for its seafoods such as crabs, cuttles,...
In short, tourists should visit Ha Long Bay. I feel comfortable and relax here. Touring experience is very good. Seafoods are delicious and at reasonable price. I love this place and I want to visit Ha Long Bay again.
