Incredibly far-flung (closer to Cuba than Cap-Haitien), but more than worth the drive, this is the first and only kitesurfing school in Haiti. The well-constructed bungalows and restaurant-bar are top-notch and will be attractive even to travelers who prefer to remain spectators. Tents for beach camping are also available and highly recommended.
The camp is perched seaside, on a cerulean bay that receives year-long downwind gusts of up to 25 knots, allowing kitesurfers to gear up fairly often, particularly in December through April and July through September. Lessons are available (US$60/290 per one hour/six hours), as is equipment rental (US$50/70 per two hours/half-day).
Other activities available include hiking to nearby historical sites, kayaking, snorkeling, sailing and motor boating. There has been vague talk to introduce scuba diving, but nothing has materialized after several years of planning. Don't hold your breath, as it were.
