La Boca is a kitesurfing spot located at the mouth of the Rio Negro on the Atlantic Ocean, near Viedma and El Condor, in Rio Negro Province. This spot offers varied conditions with flat water in the estuary and waves on the ocean. The prevailing winds blow from the west and northwest, typical of Patagonia, with often strong intensities. The spot can offer flat water on the river side or waves on the ocean side depending on wind direction. Suitable for advanced riders due to powerful winds and currents at the river mouth.
