Try Kitesurfing!

With your feet attached to a kiteboard, which is similar to a surfboard but with straps or bindings, and your arms hooked into a harness that's attached to a kite, it's possible to take a flying leap off flat water and find yourself soaring 40 feet in the air. Kitesurfing, described as a fusion of windsurfing and kite flying, was popularized by Hawaii's Robbie Naish.

Experts say it's not difficult; easier, in fact, than windsurfing and takes only a few months to learn. You'll need some equipment — a kite, board, control bars — as well as initial lessons.
