About
We invite you to sample our aloha and explore Kona’s famous warm, clear waters in an up-close and personal way. After leaving Keauhou Bay (birthplace of Kamehameha III) we head south along the cliffs toward Kuamoo Bay. Along this stretch we look for dolphins, manta rays and turtles. In Kuamo’o Bay, we head for a sea cave/ lava tube that often allows us inside it.
Heading south along Kuamo’o Bay, we follow the coastline, and paddle over coral gardens and underwater lava tubes, till we arrive at the next cave which is almost always calm and cool. Next we head to one of our snorkel spots (each day is different depending on the waves and conditions). Ample time is allowed to snorkel the reefs. The tropical fish are abundant, and if you look, you may see: octopus, uhu (parrotfish), yellow tang, butterflies, wrasse, or even a crown of thorns.
Exiting the water here, we climb up to a vantage point above the cove where we enjoy our snacks and cold drinks. From our vantage point above the cove, the water looks clear and tempts many to jump off the 12 to 25 ft. cliffs into the water below. The water is deep and safe. After a refreshing break of an hour or so, we pack up and head offshore where we hope to ride the trade winds home.
