I just got back from a 12-day trip to Costa Rica. I spent the day after Christmas ziplining through mountains and trees and clouds. We were in Monteverde, a really cool mountain town & cloud forest somewhere around 5,000 feet.
My main fear was going too fast along the lines -- I'm not a big fan of roller coasters or quick drops. But the wind was so strong that day, it turned into a fear of going too slow. When the wind is strong and you are not so heavy, it can interfere with your ride. So... my friend and I both got stuck on the lines at various times along the way, hanging on by just a cord, a hand, and lots of wind throwing and spinning you every which way. The whole thing was an amazing experience. Although I must admit, the final line was a half-mile long and while I was stuck in the middle being thrown around by the wind, I screamed at the top of my lungs "I thought this was supposed to be fun!!"
Here's a video of our experience. I got a clip of my friend, Angie, stuck on a line so you can have an idea of what I'm talking about:
I love Costa Rica!!! I was there in 2007 and really enjoyed Ziplining in Monteverde especially the longest distance which was approx 800 ft long and approx 300 ft high. The cloud forest was great, loved the hummingbird gallery. Did you go horseback riding at sunset in Monteverde? Did you make it to Arenal, I believe its called Tabascon (mineral springs). I hope to go back someday..=)
