Working in a reservation room for a while there was one question we kept answering over and over: what is the weight limit for zip-lining?
The answer you get will vary depending on the place you go. The zip line place I worked for the max limit was 270 lbs. That limit had nothing to do with the strength of the cable as there are 2 and each 1/2 inch steel cable will hold a car. The problem is momentum. Big guys/gals get going too fast and it makes for a rough landing.
Be sure to call ahead where ever you plan on going and find out for sure what their policy is.
Many college age kids will be heading for spring break so as you’re headed out to zip line in Maui (lucky you! I spent my spring break in Gatlinburg).
