Go for a stroll by the water's edge and soak up the views at Port Canal Capitainerie. The shimmering sea and bobbing boats make for an excellent photo opportunity.
When you've spent some time at this place for ships to anchor in Montauban, why not make your way to Place Nationale, Ingres Museum, and Jardin des Plantes? They're not very far from Port Canal Capitainerie and also a favorite with travelers.
