Highlights: The Garonne River flows through the urban area of Toulouse from south to north. The scenery on both sides of the river is beautiful. The historic New Bridge and the Saint-Pierre Bridge are all across the river. It is especially beautiful at night against the backdrop of landscape lights. The Garonne River is one of the five major rivers in France. It originates in the Spanish Pyrenees and flows into the Atlantic Ocean along the Gironde estuary in northern Bordeaux, France.
