5. SNUBA - It's a combination of snorkeling and scuba. You basically get the experience of scuba diving without having to get certified AND there's no heavy tank to carry. It's offered all over Hawaii, in parts of Florida and on Catalina Island! Check out Catalina Scuba Luv or snuba.com.
3. Underwater Rugby - Picture all the fun of rugby without all the injuries. Two teams of six players chase a plastic ball filled with water from one end of the pool to the other trying to score goals and earn the most points. Players wear fins, headgear and masks, but they don't get as hurt, because they can't gain as much speed in the water. Can be played in any pool near you!
2. Horse Surfing - No, the horse is not doing the surfing... you are! This combines one person on a kiteboard holding a tow rope and another on a horse, with the horse doing all the work. Seems unfair to the equine! Just say "neigh!!!" Anyway, you skate across the water at about 25 mph without using any type of engine. Talk about horsepower! There are even horse surfing competitions all over the world. You can check it out online, if you like.
1. Glacier Surfing - This might be one of the riskiest water sports around. Not many people have even tried it, but back in 2007, professional surfers Garrett McNamara and Kealii Mamala successfully rode a wave caused by a splitting glacier. They spent three weeks camping in Alaska waiting for huge chunks of the icy wall to come crashing down creating humongous waves. McNamara told CNN that it was the closest he'd ever come to death. Keep that in mind if you're thinking about trying it!
