I'll preface this by saying that I'm definitely not an adventurous or daring person by any stretch. And I still had a phenomenal time! My friend wanted to do the zipline part and I was mainly interested in swimming in a waterfall, but I thoroughly enjoyed the entire day. The guides are phenomenal and really make this an incredible experience. Our guides, Nick and Curtis were unparalleled! They were great at reading the group- for example, they knew I was pretty terrified and never made me go first for any of the ziplines or rope bridges. They were also so knowledgeable about the island and our surroundings, so we learned a lot about the area- things that only locals would know. Both guides were very entertaining too. I fully expected to spend most of the zipline portion being scared out of my mind but their humor really helped put me at ease! This tour was so scenic- the day was filled with gorgeous locations: the forest where you zipline, the lunch spot had a breathtaking view of the ocean and some cliffs, and the hike to get to the waterfall was beautiful! Also, this was the second tour that I've taken with Hawaii Forest and Trail (first one was the Epic Island Volcano your) and I continue to be impressed. Their service is amazing and I trust the company and felt completely safe with them. Lastly, the waterfall portion was truly amazing! I would recommend bringing water shoes because it is a bit rocky beneath the water and you can ruin your pedicure if you're not careful!
