Aruba is a year round kite vacation dream spot with consistent wind and warm weather almost every day. Bring 7-12m kites and lots of sunscreen!
You'll find waves and flat water to suit experts and beginners, and the trades really do blow daily except sometimes a small break in September & October.
When you're not on the water there are a ton of things to do including scuba/snorkel, exploring via atvs, boat cruises, and lots of great bars & restaurants.
If you stay in Noord you may not need a car, except if you want to ride Boca Grandi. This wave spot on the south side of the island gets great clean wind, but you'll need a car to get there.
