The staff as absolutely amazing! A few things to note!
1) They have a test zipline. I was really panicked about the first zip, not knowing there would be a small test zip from tree to tree, this makes you feel a lot better.
2) The go pro package is 100% worth it. You get endless good quality video of your entire journey.
3) THE HIKE is no joke. I have pretty severe breathing problems. However, I hike all the time where I'm from, and usually 7 miles is no problem for me. I can also do 30 minutes of stairs at the gym no problem. I think the altitude completely messed me up, that, and how very heavy the gear was. They do let you bring your inhaler but this did not help me much. I truly didn't think I'd make it to the top at one point. It's only a super short hike as well but I only walked about five steps before having almost no oxygen. I needed branches to make it up. If you have COPD or SEVERE asthma and are from a place with low altitude I highly recommend you put this near the end of your trip when you've acclimated more. Bring your inhaler. And calm your nerves because the anxiety will also quicken breathing. I was incredibly shocked at how little I could breathe. Still worth it, once you get up the hill for the second zip it's all downhill.
