Main launch spot for North wind (N/NNE/NE/NNW). In North wind, you leave from Séselets heading north for 15 km runs along the lake's axis - comparable to l'Almanarre or Serre-Ponçon in distance.
Works mainly with synoptic wind (Bise) which can blow quite strong. Big downwinds possible.
In summer: complex conditions, about 4 days >15 knots in July-August. Some light thermals 8-10 knots in evening or after rain.
Open all year round

Small free parking lot with about 30 spaces facing the beach (often full in summer). Secondary parking further south near La Maison des Pêcheurs hotel.

Very irregular wind: can drop at any moment, fins mandatory!
Airport proximity: runway 1500m away. Kite flyers have been contacted by control tower - stay vigilant about heights.
If wind dies: NEVER walk back along the road with kite in the air. Pack lines in water and deflate before returning to shore.
Riding mandatory beyond yellow buoys (200m zone). Riding >5 knots and jumps only in open water.
Important cohabitation: swimming, fishing, paddle, snorkeling. Store kites and lines, minimize time with kite in air, immediate launches/landings only.
