La Hague is a picturesque place of Precambrian granite and gneiss cliffs, coves and small fields surrounded by hedges. France's oldest rocks are to be found on its coast in Jobourg. Other rocky outcroppings on the coast include Cadomian granite in Auderville and Variscan granite in Flamanville
The dialect of the Norman language spoken by a minority in the region is called Haguais. The Norman poet Côtis-Capel was a native of the region and used the landscape as inspiration for his poetry. The painter Jean-François Millet was also a native of the region.
The La Hague site, the largest light water reactor nuclear waste reprocessing plant on earth (over half of the world's capacity), is located in the region.
