Ngu Hanh Son (Marble Mountain), a famous tourism area in the central city of Da Nang, has welcomed 5.5 million visitors during the last 15 years.

Each year, the volume of visitors has risen 15 per cent on average, according to the management board of the tourism area.

This year, the board targets receiving 600,000 visitors. To reach the goal, the board has proposed that night tours should begin at Thuy Son Mountain, the biggest mountain in the area. This is to attract more visitors to spend the night in the area. — VNS
