The Perfume Pagoda - The pagoda, or rather an accumulation of several pagodas about 60 kilometers southwest of Hanoi, is considered one of the most beautiful places in all of North Vietnam. The pagodas and shrines are in between and even inside various limestone caves.
Ho Chi Minh Mausoleum - The mausoleum, built from 1973 to 1975 in a style similar to that of the Lenin Mausoleum in Moscow, is located at Ba Dinh Square, where Ho Chi Minh publicly declared Vietnam's independence on September 2, 1945. Right after his death on September 3, 1969, Ho Chi Minh's body was embalmed by a team of Soviet experts.
The One Pillar Pagoda - The One Pillar Pagoda is one of the few monuments of Vietnam dating back to the time of the founding of the first Vietnamese empire independent from China in the 11th century.  However, the present pagoda is not the original building.  After it has repeatedly been damaged or destroyed in its almost 1,000 years of existence, it was renovated and rebuilt over and over again.
The Temple of Literature - This pagoda and the surrounding complex have played a prominent role in the history of Vietnamese thinking.  Originally it had been built in 1070 in honour of the Chinese philosopher Confucius, whose teachings have influenced Vietnam almost as strongly as they have shaped China.
National Preserve of Cuc Phuong - This national park is one of the last tropical primeval forest reserves on Earth. There are 64 species of fauna and thousands of species of flora, many of which are extinct everywhere else in the world. Bizarre and fascinating species of animals from flying lizards to monkeys dwell within the park's 61,000 acres.
Halong Bay located about 170 kilometers east of Hanoi near the most important North Vietnamese port city of Hai Phong, is of a breathtaking scenic beauty.  More than 3,000 islands, islets and limestone rocks rise from the waters of the bay.  The coast is rocky and perforated by numerous caves and grottoes with ancient stalactite and stalagmite formations.
Ho Tay Lake Water Park - The latest addition to Hanoi's entertainment parks, the Ho Tay Lake Water Park is having the same success as a similar park found in Ho Chi Minh City.  With 12 large and small slides, including some group tube rides, it is a big attraction for Hanoi families.
