Thousands of visitors descended upon Ba Vì National Park this weekend, starting in the early morning, hoping to witness the stunning cloud sea surrounding the peak of Tản Viên and greet the sunrise. The influx of tourists, primarily arriving by motorbike, resulted in significant traffic congestion on the mountain roads leading to the park. The desire to capture the picturesque scenes of the "cloud sea" drove the early and massive turnout. Authorities have not yet commented on managing the increased traffic flow. This popular phenomenon attracts many seeking a natural escape from the city. The congestion highlights the increasing appeal of Ba Vì as a tourist destination. Visitors are advised to plan for delays when travelling to the area.
