Our family of 6 all had a great time. It was our kids' first time zip lining. (kids' ages 14, 12, 11 & 8). Our two youngest are pretty small (around 45 lbs and 65 lbs)...they were able to zip by themselves on all but one of the lines where they rode tandem. Even two in our party who are afraid of heights really enjoyed themselves. It took us approximately 3 hours to do the 12 lines...only had to wait on another group one time for just a couple minutes. Our guides, Snow, Kara and Bogs (not sure I heard his name right or am spelling it right) were patient and fun to be with. There is a relatively steep hike before you start zip lining...not a problem...just something to be aware of. One thing I really liked was how they have you clip into a line on the ground to practice before you get on any platforms...really helps everyone to know what it feels like...especially for those afraid of heights.
