Extreme Orlando

Skydiving:

When it comes to sky diving it's either go big or stay home! So, if you want to go big, you can try Skydive Orlando. I haven't been there yet, but I have been to Skydive Space Center. Not only does this place boast the World's highest tandem jumps at 18,000 feet, but you also have a scenic view of the Atlantic Ocean, the Indian River, and the Kennedy Space Center including all the launch sites and the main shuttle assembly building. This was an amazing experience and I can tell you I went big, because it was also my first time in an airplane!

Rock Climbing:
While not technically in Orlando, Aiguille is the largest and most well known rock climbing center in Central Florida. The center also features classes like introductory belay, rappelling, introduction to climbing and technique clinic.

Shark Diving:

Take a cage dive with SeaWorld Orlando's Sharks Deep Dive at the parks Shark Encounter exhibit that features over thirty sharks of five species and some over nine feet long. The tour includes education on sharks and thirty minutes in the cage.

Parasailing, Skiing, Wakeboarding:
Sammy Duvall's Watersports Centre at Disney's Contemporary Resort offers 450ft and 600ft parasailing as well as Personal Watercraft rentals and tours, waterskiing, wakeboarding, kneeboarding and tubing trips. I have done the parasailing and I can say it is worth your time to go check this place out.

Skate Boarding & BMX:
I really don't think I'm agile and in shape enough to attempt these any longer, but if you are, then check out Vans Orlando Skatepark and Orlando Skate Park.

Indoor Skydiving:
If you're not quite brave enough for the real thing yet, or just want to try something new and exciting, SkyVenture Orlando Indoor Sky Diving features a 12 foot, open flow, 1000 HP wind tunnel that gives you the sensation of flying on a 125 MPH column of air.

Hang Gliding:
Wallaby Ranch was the birth place of aerotowing, which makes this exciting sport available here and not just off the side of a mountain. With tandem aerotowing, a two-place hang glider is being towed by a specially designed ultralight towplane up to 2000ft and then released for a 15 to 20 minute free-fly.

Human Sling Shot:
"Catapult 365 feet in the air with extreme force, all powered by giant cables and springs!" How does that sound to you? Good, well climb on board the Human Sling Shot at Old Town then.

Free-fall Water Slide:
Orlando is home to one of the World's tallest and fastest free-fall body slides.  Located inside Disney's Blizzard Beach is the Summit Plummit, a 12-story thrill ride that sends you down a 360-foot long flume and through a darkened tunnel at a speeds reaching 50 to 60 miles per hour!

Airboat Ride:

Glide through the Florida wetlands on an airboat tour by Boggy Creek Airboat Rides. Start out with a leisure wildlife tour and then travel up to 45 miles per hour through the wild swamp lands. If that's not enough for you, how about doing it all in the dark with a night tour and search for the native Florida alligators.

Orlando has a lot of these, so I'm just going to name drop a few by park that you would definitely want to check out.
