text: I did the low line zip with my bestie and my cousin did the high line now open superman style It was Labor Day weekend the Monday after and it was HOTnnYou sign up downstairs and pick a time slot it fills up at dark if you sign up about pm you are going to be looking at zipping around pmnnYou wait around until your time slot is called we did slot and walk up a flight to be weighed fitted and put in an elevator to go up to zip We waited about minutes during this time frame I thinkbecause we zipped right at the start of the Freemont experience which is every hour on the hournnZipping You are attached to the harness on the wire then step forward to a cattle gate which opens at one point You walk down the stairs about and sit in your harness so you are dangling At this point they release the lever holding your harness in place and you slowly build up speed to about mph as you zip across the street onto Freemont nnThe stop is the WORST part It is a HUGE jolt my besties neck was very sore the next few days and they warn you not to hold the harness too close to your face or you can knock yourself outnnIt was an adrenaline rush and it was a bit more scary to me than zipping in Jamaica It goes by pretty fast so I would recommend enjoying the ride and not paying attention to anything elsennI said I would never go again the night we did itbut I have already changed my mind For it is one of the best things to do in VegasnnTIP You can reserve your slot online way ahead of time do that if you are a planner We just were not sure when we might be going downtown at the time
