This was by far my most exhilarating experience during our 10 day stay in Hawaii ( which included lava tours, cliff jumping, snorkeling, whale watching). The zip lines themselves are spectacular. I was very nervous to begin, but Skyline does a great job by starting off on a couple smaller lines to get used to the lines. The best part of the experience was the guides!! It started off when Giggles(very fitting nickname) told me it was his first time as he was fastening me into my harness!! Blake and our other guide (I'm so sorry but can't remember his name) were fantasic. They were funny and even educational, stopping on our tour to let us have fresh bananas and berries. They assured our group that they would do all of the work and it was our job to have fun. They eased us into being able to turn side to side to get the best view of the waterfalls(several). By line 4, I was doing 360s!! Great fun, great views, great guides!! Only regret was I didn't rent the camera, but I will save that for next time.
