Location

The NHML is in a very known place (the Place de la Riponne) and there's some pretty dodgy stuff over there, watch out. You can take the bus directly into town stop at Bel Air, take the street up to the McDonald's, continue forward right into the square.This area also offers great food including the classic McDonald's, and some very good japanese food at the Haiku. If your parents or any adult brings you there, there is a very convenient car park right in front of the Natural History Museum! If the map is not enough you can see it in google street view!
