This safari was the perfect balance of the three things our group of five wanted to do, without any one activity being so long that it became tedious. The kayak trip was about 45 minutes of paddling and not difficult. The walking trip was easy and the swimming holes were beautiful. They do require the ability to walk sure footed though. Our oldest member at 70, with some health limitations, was able to do it though slightly slower then most of the group. The group leaders were very accommodating. The steep climb was done via a wagon ride up the hill to the zip lining site. Lunch was before the zip line activity and was very good. The zip lines were great fun for all. The walk out took us to the a line with a drop into a beautiful swimming hole. The walk out was mostly level and took us back to where we had kayaked in. A motorized boat brought us back in about 20 minutes. It was a great active day but not exhausting. Our group was 32, 42, 44, 65, and 70. All of us had a great time. It was the perfect way to start our visit to Kauai. I would definitely recommend this safari tour.
