Wasn't sure exactly what we were getting ourselves into, but we ended up thoroughly loving our adventure. The 2.5 mile kayak voyage as not as hard as we thought it would be. Then we hiked through rivers and dense vegetation to end up at a beautiful waterfall. Swan under the waterfall and had a quick lunch before trekking back to the kayaks. What made the trip perfect was that we were the first group of the day, which meant we got to enjoy the waterfall before it became overrun with other tour groups. And to top it off, our tour guide, Thomas, really showed his teaching roots by pointing out different plants, rocks and birds. He really knew his stuff and shared it in a fun and interactive way. Highly recommend this trip and Rainbow Kayak Tours to anyone coming to Kauai.
