Spot Guide & Local Knowledge

Punta Trettu, situated in southwestern Sardinia facing the island of Sant’Antioco, is one of the Mediterranean’s most celebrated flatwater kitesurfing arenas. The long, sandy spit juts out into a shallow lagoon, creating a natural windbreak that guarantees dead-flat water even in 30 knots of wind.

The Venturi wind engine

The strait separating the Sardinian mainland from Sant’Antioco forms a natural bottleneck. When the Maestrale (Northwest) sweeps across Sardinia, it funnels through this channel, consistently adding 4 to 8 knots above regional weather forecasts.

Riding zones and bottom topography

The spot is divided by the sand spit into distinct zones. On the sheltered leeward side of the spit, the water is as flat as a sheet of glass, perfect for freestyle training and board-offs. The bottom is fine sand mixed with soft silt, and the water stays waist-deep for several hundred meters from shore.

Crucial navigation rules

Riders must strictly avoid the deepwater commercial shipping channel used by ferries and fishing vessels heading into Portovesme. Dedicated kite schools monitor the safety zone, and entering the ferry passage will result in fines and spot access restrictions.
