The park's Tourism and Environmental Education Centre said visits, tours and related services had been suspended from noon on September 23 until further notice to ensure the safety of residents and visitors.
Nguyen Thanh Trung, director of the centre, said the decision followed recent moderate to heavy rain and thunderstorms across parts of the park.
The conditions have increased the risk of landslides, falling rocks and trees, slippery trails, localised flooding and flash floods, posing risks to visitors.
The park includes steep terrain, trails, streams and ravines, with some areas prone to landslides, falling rocks, slippery conditions and strong currents, particularly during heavy rain.
Tour operators, businesses, guides and others providing ecotourism, trekking, camping and outdoor services have been asked to stop taking visitors to affected sites and routes during the suspension.
They have also been told to inform customers who have already booked trips and adjust their schedules to ensure visitors are not trekking, camping or taking part in outdoor activities in unsafe weather conditions.
The park said service providers would be responsible for complying with safety requirements and the temporary suspension.
