The area around Los Barriles is world famous for its kiting and windsurfing. The main reason naturally is the WIND! How clever is that? Actually the best part is that the wind is generally parallel to to beach. Not offshore; not inshore. That means you can take off from the beach, go groove in the wind for awhile and sail back in without a bunch of brutal tacking maneuvers. During the winter, the wind is from the North mostly; summer it comes mainly from the south.
The most well known area is called "North Beach." It's located North of Los Barriles. Go figure. A newer hot spot is between Los Barriles and La Paz called "la Ventana." Great winds and less well known.
This video is from Exotikite. They have a school and store in Los Barriles. I can't recommend one school over another from personal knowledge but my grand daughter and her boyfriend both work for Exotikite. What are ya gonna do?
If you're a kiter or windsufer, check out the Lord of the Wind contest being held here in January. This is going to be huge, get your hotel reservations soon.
