Staying overnight at Ba Na Hills is the single best way to experience the mountaintop. 
Even better, staying overnight grants you exclusive, crowd-free access to the iconic Golden Bridge at sunrise (6:00 AM) before the first daytime cable cars arrive from the valley below.
Mercure Danang French Village Bana Hills (Top Pick): This 4-star Accor property is scattered across 7 French-themed villa buildings right in the middle of the complex.
Watch the fog roll in as the ambient Gothic street lamps light up. 
A must when visiting Da Nang.
