The beach activities outside the Marriott Resort in Aruba are much the same you'll find at any beach resort—tubing, waterski, jet ski, stand-up paddleboarding. But what you won't find at many others is a certified yoga instructor ready to teach newbies how to practice the art of vinyasa atop an unbalanced paddleboard. Rise early and head down just as the activities shack opens to catch the morning rays before the ocean fills with the day's adventures. The added complication of staying on your board tightens and tones parts of your body previously unreached. And the peace you'll feel drifting under the Caribbean sun is one unreplicated in your local yoga studio.
