Lachanau (Lac d’Hourtin)

Lachanau (Lac d’Hourtin) is a shallow, sandy freshwater lake spot on the east side of the lake, best known for flat-water kitesurfing in a clearly defined kite area marked with yellow buoys. The conditions are typically very approachable for progression thanks to the broad shallow zone and generally negligible currents, but you must be disciplined about where you ride and launch. Wind is described as thermal-driven and especially dependable from late spring into early autumn, with the most favorable months running from June through October (and a wider May–October season overall). Multiple sources highlight afternoon reinforcement from a southwest-to-northwest component, with typical winds around the 10–20/12–25 knot range. For safety and comfort, wind direction matters: north, west and southwest are favored, while easterly winds are noted as offshore and can be gusty. The beach/launch setup is framed by trees and vegetation. That makes rigging and first kite handling more technical—particularly when the lake level is high in spring, which can reduce the usable launch space. There are also noted submerged hazards in shallower edges (alios/flat rock and some underwater obstructions), so riders should avoid the shallow margins outside the main sandy area. Seasonal rules are important at this spot. Kitesurfing is restricted to the designated kite zone/channel, with additional summer enforcement: the spot is closed in July–August due to swimming zones, and kitesurfing is prohibited before 19:00 except in a reserved Super-Sud area. Emergency access is available via 112.
