We visited Kauai in May, and booked the "Secret Falls" kayak/hike trip with Kayak Wailua -- two couples with very limited kayak experience, including one who was still recovering from a broken foot. Because of that, we opted for a small-group trip (consisting of just our foursome, plus the guide). Check-in was easy and quick, with no up-sell or hidden costs (there were options for different equipment, but no pressure around any of those choices). As novices, we got a straightforward briefing on two-person kayak safety and practicalities (how to get in and out, how to handle the boats in the water, how to most efficiently paddle), and were then off to the river (a quick trip). Our guide, David, was outstanding. He had an easy, friendly manner, and gave us good advice on handling the kayaks. He was also good company, and truly knowledgeable about the river, the natural setting, the flora and fauna, and Kauai/Hawaii in general. He gave us choices as to how we wanted the trip to unfold (also giving his professional opinion as to what would work best). We opted for the hike to the falls (our broken-footed kayaker patiently waited for us), which was worth the trip, even on the somewhat muddy trail (David warned us in advance that the trail might be muddy, given recent rains, so we made an informed decision to try it). David snapped pics of all of us through the day, and shared them with us later, which was great, as we had forgotten cameras. In every dimension, a great trip with a wonderful guide. Would definitely recommend it.
