The Ebro and Rio are two rivers in Spain. The Ebro is the longest river in the Iberian Peninsula, stretching over 800 miles from its source in the Cantabrian Mountains to its mouth in the Mediterranean Sea. The Rio is a much shorter river, only about 200 miles long, and it flows through the city of Madrid before emptying into the Atlantic Ocean. Both rivers are important sources of water for the country and provide a variety of recreational activities for locals and tourists alike.
