I live near for almost one year and I can say that this city is really safe compared to many other tourist destinations, at night streets are almost empty ( but I’m sharing my own experience and i’ve never left busy areas during the night )

After traveling in many different countries as well as living all over the United States, Biarritz is absolutely one of the safest places I’ve ever experienced. Based on what I’ve seen it’s tranquil and respectful — a very clean city where people go out of their way to be polite.

You can definitely walk around Biarritz and not really be worried. From all my nights out, I have never had any problem or anything but I think people should still be careful at night anywhere, even in Biarritz.
