Not the best Zip Line you can ever experience but what more can you do when its located in downtown Vegas. $20 for one try but I believe it's cheaper before 6pm.
If its your first time ever ziplining, I'm sure you'll have a blast and if you're a lady I suggest wearing a skirt if you like attention. Law of physics will also play a part of how fast you will go. I estimate the zip line having about a 25% angle going down from start to finish, so the more junk you have in your trunk, the faster your ride will be.
Go at night because the experience is better with the ceiling light of fremont putting on a show while you're up there. Next time maybe I'll wear a skirt to put on a show for the ladies. Who am I kidding, i'm filipino....not that much to show if you're comparing me to your ex black boyfriend.
