Cúc Phương, established in 1962, holds the title of Vietnam's first national park. It is a place of incredible biodiversity, home to thousands of species of plants and animals. Every year, many people, including students on school trips, visit to experience its natural beauty. However, this popularity creates a difficult question: how can the park welcome visitors while also fulfilling its primary mission of protecting its delicate ecosystem?

The park's commitment to conservation is its most important duty. This is most visible at its world-famous Endangered Primate Rescue Center. This center plays a vital role in protecting and rehabilitating rare monkey and langur species, many of which are found nowhere else on Earth. By focusing on these vulnerable animals, the park serves as a critical sanctuary, ensuring that future generations can appreciate Vietnam's unique wildlife.

While tourism brings necessary funds for conservation, it also presents negative consequences. A large number of visitors can lead to problems such as litter left on trails, noise pollution that disturbs animals, and damage to plants. Park managers work hard to manage this impact, but they depend on the cooperation of every visitor. The challenge is to educate people so that their visit helps, rather than harms, the environment they came to enjoy.

Ultimately, the future of Cúc Phương depends on responsible tourism. Visitors have a role to play by following park rules, staying on marked trails, and respecting the wildlife. By understanding that the park is not just a tourist attraction but a precious natural treasure, we can all contribute to its preservation for many years to come.
