La Caserne at Gâvres is a lagoon-style kitesurfing spot located in Brittany, France, characterized by a series of connected shallow ponds and saltwater basins separated by dikes. The coastline faces northeast toward the Atlantic, with a sandy beach strip providing access to protected lagoon waters. This spot is primarily suited for beginners and intermediate riders seeking flat-water or very small wave conditions. The enclosed lagoon environment offers natural wind channeling along the northeast-southwest axis, making northwest winds ideal for side-shore conditions. Water depths are generally shallow, creating both safety benefits and navigation constraints. Average wind conditions are modest at 10 knots with relatively low reliability (25.5%), suggesting this spot works best during Atlantic weather systems. The industrial ponds and embankments require careful route planning to avoid obstacles. Wave activity is minimal (1.03m average), making this location suitable for progression rather than wave-riding. Best visited during autumn and winter when Atlantic storms increase wind frequency. Water temperature is cool year-round, necessitating appropriate wetsuits.
