I was both terrified and very excited for my first real zip-lining experience (the first time involved zip lining across a river in Cusco with gloves that were half broken). We booked with Original Canopy due to the high ratings on TA, and they did not disappoint! We reserved for the 7:30AM tour and were promptly picked up from our casa around 6:45AM. There were a total of 4 people, plus 2 guides on this tour - it wasn't very crowded, the guides were very attentive and helpful and FUN! The Tarzan swing was the scariest for me, the first warm up exercise, but I felt safe the entire time. We started with some shorter practice lines, then rappelling down a tree / climb up a hollow tree (strangler fig). The guides, David and Camber (sorry if I misspelled!!), were really great at explaining instructions, checking equipment, and not to mention great photographers! (they will use your camera to take pictures of you and videos of the ziplining so you can enjoy the experience, and then take home memories).
Overall, LOVED the experience, especially the two last lines (800m and 500m) both with fantastic views of the canopy and the Pacific Ocean. Highly recommend booking with Original Canopy and reserving the 7:30AM - the early morning is so worth it!
