I am planning to go to Vietnam for more or less 12 days next year. I am looking for a good map to mark up routes and sites for historic areas and parks in some of the major cities. I can't see inside any maps on amazon except 'groovy' series. And it doesn't seem fitting for my purposes. Also, AAA doesn't have a map for almost any country in Asia.
Does anyone have a recommendation for either paper or travel maps that have blow-ups of areas?
Lots of the maps online for Vietnam relate to historic eras. I want something close to current, since I don't want to plan to visit a site that no longer exists.
I also thought there might be a "helpful resources" page like for some other SE sites, but couldn't find it.
