Northern Vietnam, while bustling with activity, tends not to have a high degree of street harassment. Women are generally treated with respect and the locals are often more respectful to travelers. However, that doesn't mean it is harassment-free. It holds good to be aware of one's surroundings, not to move around in secluded areas alone especially late at night, or at least inform someone before doing so. As in any place, occasional unsettling situations may still occur, but overall, many solo female travelers report feeling relatively safe in this area.
