Nothing makes us happier than sharing our love of the sea, and the magic of this island, with everyone we meet. Oahu is a very special place, and many of the most breathtakingly beautiful locations are only accessible by boat. It is important for us to provide a means for our guests to observe the abundance of amazing creatures that inhabit our waters, and to observe these animals existing wild and free - as they should be. Our hope is that after an excursion with Kapu Kai, you will leave feeling connected with these precious waters, and the mana that lies within.
