Tourism resources are all-natural, cultural and social factors that can attract tourists to the destination. Tourism resources in national parks not only create biodiversity but also are the premise for tourism development. One of the characteristics of tourism resources is their vulnerability. Therefore, the problem is that the exploitation of tourism resources must be associated with conservation and this is vital for national parks and tourism activities. This study was conducted to explore the conservation activities of tourism resources in U Minh Ha National Park. Research data was collected from a survey of 30 officers and employees working in the National Park. Descriptive statistics were used to analyze the data. The research results show that there are many measures used to conserve tourism resources. Of the proposed measures, five were rated as the most effective (over 50% of responses): Developing a canal network to limit the scope of forest fires and facilitate firefighting; Actively guarding and patrolling; Setting up warning signs for forest fire forecasting; Conserving water all year round, limiting forest fires; Releasing animals back into the forest. The research results supplement the theory of tourism resource conservation and the practice of tourism resource conservation in national parks.
