Lagune du Letty is a shallow coastal lagoon in Brittany, France, separated from the Atlantic by a sand barrier beach. The estuary receives freshwater input creating a brackish environment with complex tidal dynamics. The lagoon offers protected, flat-water conditions ideal for learning and progression, with depths generally 0.5-2 meters. Wave energy is minimal due to the sand barrier protection, making this suitable for kiters seeking consistent, smooth conditions rather than swell. Wind-driven chop dominates rather than ocean swells. The spot faces west toward the Atlantic, making northerly or southerly winds ideal for side-shore conditions. With average wind reliability of only 16.5% and modest average wind speed of 8.4 knots, sessions may be inconsistent. The shallow lagoon environment requires awareness of tidal changes, as exposed mudflats appear during low tide. Beginner to early intermediate kiters benefit from the forgiving flat water. Residential proximity limits session duration and requires consideration of local access.
