Sand sailing (char à voile) is Berck's signature activity — three-wheeled land yachts driven by the wind across the firm beach sand, reaching speeds that can genuinely alarm first-timers. The Opal Coast wind makes Berck one of the best places in France for the sport, and the beach is wide enough to run proper courses without conflict with swimmers or walkers.
Several schools operate from the Esplanade Parmentier, offering two-hour introductory sessions with all equipment provided. Dress for the wind: a helmet is mandatory but you will also want waterproofs and closed shoes, since the sand spray is considerable. The Éole Club (Esplanade Parmentier) is the longest-established school and runs sessions for individuals and families daily in season, weekends only off-season. Booking in advance is recommended in July and August.
