The Best spots are in the East of Culebra :
"Las Pelas" is one of the best spots. Here are two videos in " Las Pelas"
You need a boat to acess this spot and I think that
the best spots in "Culebra" and "Culebrita" are boat access only.
"Ensenada Honda" is a big bay with open areas on different small spots that you can kite.
Launching would be from water only.
In "Las Pelas" and "Ensenada Honda" you can find a lot of boats anchored usually
there is more boats during weekends. But Culebra is not a place that you would find a
lot of kiters probably you would be kiting alone.....................
Flamenco Beach is on the North Area of Culebra and can be acess by car and is one of the most famous beaches in Culebra is not considered a kite spot but with the correct wind direction you can kite this beautiful beach. I think that during December you have a chance to kite in Flamenco Beach. I found this video with a quick search.
