We went on a zip line tour while we were in Manuel Antonio. It was great. We were over 100 feet above the ground, strapped into a harness, and sent zipping through the forest. It is hard to see what is all around you since you have to concentrate not to spin and run into an adjacent tree. It all happens pretty fast. Once you are on the platforms though you can see all around you. The guides are really professional and we had a man who told us a lot about all the medicinal trees and animals. There was even a 5 1/2 year old that went on the trip. These pics were taken by the tour company which is nice since I am usually behind the camera and we have few pics together.
