Local association recommendations

Emeraude Kite (emeraudekite.com) — the local reference association, manages spot regulations on the Côte d'Émeraude and publishes a weekly safety bulletin. EVORIDE (evoride.fr) — itinerant kitesurf/wingfoil school, moves between Le Sillon and Baie de Lancieux depending on conditions.

Spot functioning

Main meeting point: at the Surfschool / Thermes Marins. Freeride or waves depending on tide. Waves mainly on the east side (Rochebonne), chop on the west side. Specific summer regulations — check the Emeraude Kite app or emeraudekite.com before each session.

Spot opening date · Required level

Spot opening date: Open all year round
Required level: Intermediate

Wind specificities

Works from west to north-east. Depending on wind direction, riders move toward Fort National (west wind) or toward Plage du Pont (less disrupted wind). Waves on the Rochebonne side (from Surfschool east) or chop depending on tide. Wind sometimes disrupted by the seawall and ramparts at high tide.

Hazards

Rocky areas invisible at high tide — exposed at low tide, vigilance required as danger zones shift. Historic wooden breakwater posts dangerous at high tide — invisible traps. Beach narrows significantly at high tide (even small coefficients): riders end up close to breakwaters, seawall and tourists. Significant co-use: long-distance swimmers, surfers, windsurfers, sand yachts, walkers, bathers — kite not priority. Specific summer regulations (see emeraudekite.com). Not recommended for beginners.
