Skydiving is simply awesome! It's definitely for the risk takers in life and if you can do the serious roller coasters, you'll love this! You only get about 20 seconds of free fall but it's a scary and incredible feeling that I've never gotten doing anything else. Ironically, I was super nervous about the experience until I got on the plane. (very weird, I know) I think it's because I realized I wasn't jumping out of this plane with just me and the person I was hooked up to. You'll jump with a group of people. Also, it doesn't seem like you're that high in the air from where you jump but I jumped about 15,000 ft!
Most of my nerves prior to jumping were because I wasn't 100% sure how this worked and the waiver you have to sign is very demanding but for good reason. If you ever have a chance to skydive, I highly recommend it. It's one of those things in life that boosts your adrenaline and lifts the stress of life off your shoulders. I am actually planning on doing this again next year with one of my friends! If you aren't a roller coaster lover, I would say zip lining is the best thing to try. I've never done it but I've heard from people who don't like roller coasters that they really enjoyed it.
