He could meet Fleur Delacour's family. Since Fleur is from France, her family might be an important part of the French wizarding community that Harry interacts with.
Well, he might visit Beauxbatons Academy. Maybe he would meet some new friends there, like some interesting French wizards or witches. He could also explore the French wizarding culture, which is likely different from what he's used to in England.
Well, if Harry Potter goes to France in fanfiction, perhaps he would visit the Beauxbatons Academy. He could learn about their different styles of magic education. There, he might make new friends and enemies. Maybe he'd get involved in some sort of international magical competition that involves both Hogwarts and Beauxbatons. And who knows, he could even discover some long - lost French magic spells that could help him in his future battles against the Dark Arts.
Well, it could be that Harry goes to France on a secret mission. Perhaps he's following a lead on a dark wizard who has ties to France. In France, he might have to adapt to different magical customs while trying to complete his mission.
In fanfiction, Harry Potter going to France could lead to an adventure where he gets involved in a mystery related to a powerful French magical artifact. He'd have to team up with local wizards to solve it and in the process learn about the rich history of French magic.
Another unique feature can be the settings. Some fanfictions might introduce French locations like the French Ministry of Magic or French wizarding villages. These new settings can bring in different types of magic, different magical creatures that are native to France, and different social structures within the French wizarding community. This all adds a whole new dimension to the Harry Potter universe that we know from the books.
He could meet French pure - blood families who have their own long - standing traditions. For instance, there might be a family that has a special connection to a particular magical forest in France.

Well, one way could be through a magical accident. Maybe a powerful spell gone wrong transports Harry Potter to France and, due to some strange magic laws there, he ends up being proclaimed king. For example, if the spell disrupted the line of succession and the magic of the land recognized his powerful magic from Hogwarts as a sign of leadership.
