The management board of My Son Sanctuary has officially inaugurated a 2km road connecting the Khe The Bridge to the central group of Cham towers.
Management board head Phan Ho said the road is one of the first trekking routes in the UNESCO-recognised world heritage site.
He said tourists have differing tastes, some might prefer walking under a canopy of trees, and so different paths will be developed.
The management board also provided 10 battery-powered cars to transport tourists from the entrance to the towers.
According to Ho, more dinning, shopping and guesthouse services will be available this July to keep tourists at the site for longer.
The world heritage site hosted 102,000 tourists in the past four months this year.
