20 Fascinating Fun Facts About Vietnam

Vietnam attracts a growing number of visitors worldwide each year, thanks to its impressively long coastline, uniquely captivating culture, and irresistible cuisine that leaves you wanting more. Beyond these trademarks, the country boasts various astonishing facts seldom found elsewhere. Drawing on our knowledge and experience accumulated over the years living in this wonderful country, we will guide you through the top 20 special facts waiting to be explored about Vietnam.

1. Home of the largest cave in the world

Son Doong Cave was discovered in 1990 in Phong Nha-Kẻ Bàng National Park, Vietnam – a UNESCO Heritage Site – by a nearby farmer. However, it was not until 2009, during the British–Vietnam Cave Expedition, that the destination was officially surveyed and measured, leading to its recognition as the largest cave ever found. The cave stands 200 meters high, 150 meters broad, and is 9 kilometers long, with a scale capable of holding a 40-story building.

The extraordinary and mysterious underground world within Son Doong is the reason for the cave's worldwide fame and renown. It has its own ecosystem, weather, and a mysterious underground river that no explorer has yet traced to its end, along with many complex and giant stalactites (over 80m high).

2. A system of long and massive caves 

The longest cave in Vietnam, Thien Duong (Paradise) Cave, stands as a captivating marvel nestled in the heart of Phong Nha-Ke Bang National Park. Stretching an impressive 31 kilometers, this underground labyrinth reveals an enchanting world of geological wonders. The cave showcases a mesmerizing array of stalactites, stalagmites, and intricate formations, each contributing to the awe-inspiring beauty of its subterranean landscapes.

Beyond its geological allure, Thien Duong Cave may harbor unique biodiversity, creating a distinct ecosystem within its confines. This underground realm could be home to rare species of flora and fauna, adding to the cave's ecological significance.

3. The Cu Chi tunnel network 

The Cu Chi Tunnels, a renowned historical site, are located 70 kilometers from the center of Ho Chi Minh City (Saigon). During the war, the Viet Cong dug these tunnels under Vietnam to evade aerial attacks and later utilized them as a means of transportation between their homes. Remarkably, they extended for a total length of 200 kilometers! This impressive structure also served as a complex, featuring clinics, kitchens, meeting halls, and even a weapons vault. The 120 kilometers of tunnels preserved over the years have been transformed into a war memorial park.

4. Red weddings

Weddings in Vietnam follow a slightly different ritual than those in the West, and they are a significant celebration, often with as many as a thousand people in attendance. Unlike Western weddings where white is predominant. In Vietnam, the color red holds more cultural significance. Traditionally, brides wear red attire on their wedding day, with the red Ao Dai being the dress of choice for almost all Vietnamese girls. This choice is rooted in the belief that the color red symbolizes happiness and will bring good luck and joy to the newlyweds.

5. Extraordinarily thin buildings

Hanoi boasts a skyline adorned with modern skyscrapers, traditional tenement buildings, and remarkably compact blocks — some as narrow as a bicycle! In the nation's capital, these unique structures are referred to as 'nha mong,' and there are 179 of them. Typically, these buildings, found in various parts of the city, consist of five levels. The Ba Dinh District, in particular, is home to 44 of these distinctive constructions, easily visible in the cityscape.

However, since 2005, the government has implemented a rule prohibiting the construction of such petite homes. This regulation stems from concerns about the buildings' resilience to earthquakes, necessitating a minimum width of at least 3 meters.

6. The cheapest beer in the world

In Vietnam, you can always find good and affordable beer! Bia hoi, often referred to as 'steaming beer,' is a type of barrelled beer sold within 48 hours of being barrelled. Its unique characteristic is that it spoils quickly due to the absence of pasteurization. The traditional beer in Vietnam offers a more flavorful experience, particularly during the first 36 hours after the barrel is opened, gradually developing a distinctive sour taste over time.

13. Snake-wine

A popular tincture in Vietnam, known as 'ruou ran' or snake vodka, is made using a snake, preferably several dangerous ones.

In Vietnam, snake flesh is believed to have health benefits, contributing to improved well-being and extended youth. The combination of snake and alcohol in 'ruou ran' is thought to cause the degradation of snake venom, rendering it harmless to drinkers. While these practices exist, it's important to note that views on their efficacy can vary, and they are often deeply rooted in cultural beliefs. As always, individuals should exercise caution and consider cultural contexts when exploring such practices.

Enthusiasts often transform their gardens into 'miniature forests,' adorned with numerous trees and even aquariums. The craft of creating custom bird cages, skillfully executed using bamboo, adds an artisanal touch to this cherished tradition.

This exquisite balance not only tantalizes the taste buds but also reflects the intricate connection between Vietnamese culinary traditions and the broader cultural and elemental influences that shape the nation's rich food heritage.

Delve into dishes like 'ngu vi huong,' where the five-spice blend elevates the flavors of various meat dishes, or savor the aromatic 'pho bo' with its robust broth featuring a careful fusion of spices.

18. Water puppet theater

Vietnam is the birthplace of water puppets, wooden and vibrant creations that take on the roles of actors in traditional plays, but with a unique twist — they perform on water instead of a traditional stage. Behind bamboo screens, skilled animators manipulate these puppets, a task that demands considerable physical effort. These effigies, weighing up to 5 kg and standing as tall as 100 cm, showcase the intricate craftsmanship and artistry that make water puppetry a captivating and distinctive cultural performance in Vietnam.

19. Fair markets in the mountains

In the foothills of northern Vietnam, the town of Bac Ha hosts thriving, vibrant, and colorful marketplaces.

In addition to the lively commerce, Bac Ha's markets are a kaleidoscope of cultural exchange. The atmosphere echoes with the chatter of local dialects, creating a rich tapestry of traditions and stories.
