Just as you’re picking a place with less light pollution, you need to select a time of the month when the moon won’t be as bright, or preferably not visible at all. If you want a picture of a clear milky way against a black sky, opt for new moon timings. Depending on the foreground, I prefer to have some lighting at the scene because a little natural light helps enhance other details of the surrounding area. If there isn’t any light then I will sometimes use the light from my iPhone or a torch.
