This was a first time zip lining experience for me, my husband and my 17 yr old. The guides did an excellent job making us feel comfortable. They obviously were very knowledgeable about zip lining and we felt comfortable right from the beginning. The course starts out with a very easy zip line and builds to longer zip lines from there. At the end, you zip line over a magnificent waterfall and in between are treated to zip lines through a beautiful rainforest area with lines criss crossing steams. The guides take photos, point out trees of interest and make it a fun time. Definitely a highlight of our trip! If you are hesitant about zip lining but have always wanted to try it, this is the course for you!
