Spot at Camping de Colombier beach. 

Off-season spot as the beach is very crowded as soon as the water temperature is good. It's also a spot that gets loaded with seaweed, making foil launches very complicated from mid-June onwards (In any case, unless the weather is bad, there will be too many people on the beach to launch a kite safely).

Full on-shore spot, so not ideal at all for beginners.
Since you're launching from a swimming area, you must first exit it by body dragging before getting on your board. As a reminder, you are considered a navigating craft and therefore subject to fines in swimming areas, both for kite and wing.
