Final answer:
France is the country with the Pyrenees along its southern border with Spain, acting as a natural geographical divider.
Step-by-step explanation:
The country that has the Pyrenees in the south along its border with Spain is France. The Pyrenees are a significant mountain range that serves as a natural border between Spain and France, extending from the Bay of Biscay to the Mediterranean Sea. The range includes rugged terrain and peaks that are well-known for their beauty and outdoor sports opportunities. This landscape not only creates a physical division but also has historical implications, as it has played a role in the geographical isolation of the Iberian Peninsula from the rest of Europe.
