Da Nang, located almost directly between
Ho Chi Minh City and
Hanoi, is the third largest city of Vietnam.
It has a lively feel to it, but more of just being a city, and less of a entertaining destination for the wondering traveler and tourist. If you want that, go visit its southern neighbor
Hoi An.
Hoi An was the focal point for the French-Indochina, acting both as administrative hub and port. But as the river suffocated itself with silt, Da Nang replaced it as the port city and grew to be the 3rd largest city of Vietnam.
Hoi An is just a few minutes away. So that means that the day trips to places like Marble Mountain, Monkey Mountain, etc. are still options.
But otherwise, there are two major museums in Da Nang (Cham Sculpture Museum and the HCM museum) and that is it.
