There are a number of different zip line outfitters and most of the hotels seem to be happy to either offer their own tour or a trusted provider in reference. I’ll post links to some of these services and try to organize them geographically in the activities tab.

Zip lining is essentially an activity that involves a series of platforms ranging in height from 50-100 ft high built into the forest at 100-250 ft intervals. A series of wires run the length of the course. Through some careful rigging (harness, a hook and wheel, etc.) one can attach himself/herself to a cable at one of the platforms. A leap of faith and gravity lets one ride through the air along the length of the cable to the next platform at breakneck speeds. Really, it’s more like 20 mph. Once the next platform is reached, some friendly guides secure the individual and set them up for the next platform.

Most zip trips offer several platforms and cover quite a lot of jungle real estate. The fun is in the speed and feeling of flying. The jungle sights and sounds are likely mostly missed due to the speed and noise of the zip.

But most who try it, love it. I suspect that Liz and I will marvel in the adventure, especially if I get one of those awesome helmet mounted cameras for the trip.

Hygiene Follow-up
It appears that there is a high likelihood that Zip Line tour operators have a limited set of helmets which they reuse multiple times within the same day. In a jungle environment, this translates to hot, sweaty, smelly, helmets with a very high “yuck” factor. Keep this in mind and perhaps pick up a handkerchief to wear while sharing the browsweat of your neighbor. We recommend these: Belize Bandanas to give yourself that “I’m a tourist and proud of it” vibe.
