Scuba Diving with humpback whales.

Whale season is upon almost here, with a sighting by boat last week here in Maui. Our humpback whales travel from Alaska in the winter to the Pacific Whale Sanctuary in Hawaii to calve and breed. 

Whales travel thousands of miles without feeding.

There is not a food source in Hawaii, and these whales do not feed, but live off their summer reserves for the season.  By the time they return to Alaska in the spring, they are fairlly emaciated and have the appetite of….you guessed it …a whale!

Happy 2016 to all our fans and  clients.

We are off to a great year with the Hawaiian Humpback Whales showing up just in time for the holidays and providing background music for our underwater tours. If you love the whales as much as we do, join us daily on a Kayak Whale Watch Tour thumb-kayak-eco-snorkel-480x360an hour and a half easy paddle out to visit with the whales. Mother and calves, with their escorts, or solo singing males are awesome and gentle creatures to experience on Maui;s calm waters.


Check our website for all our tours and instruction possibilities. Whales season ends May 15th, but the best action is from now through the end of March. In February there is a Saturday “whale count” throughout the Hawaiian Islands and in the past there averages around 10,000 whales sighted! Often over 2/3rds are around the island of Maui. Talk about good odds of seeing a whale! We like to skip the crowded boats and have an intimate, peaceful; interaction with our large sea mammals visiting from their summer in Alaska. Our tours are semi-private groups of up to 8 people or as a private tour with just your party and a guide. All our guides are professional photographers, as well as whale lovers! We provide an amazing and safe experience that often jumps to the top of peoples life adventures.


Bring your hat, sunglasses, and rashguards and let’s go whale hunting!

PageLines- wailea-beach-250x188.jpgAloha from Maui! Our reef today was so epic. Over 100′ visibility let us see across the reef. Turtles, eagle rays and more were easy to spot and track their behavior by all our divers today. Paddle boarders were raving about being able to see straight down to the reef, while Opelu Kala (White-tailed Unicorn Fish) were schooling near the surface feeding on micro-plankton. The sea life is so abundant. The winds are in a light phase right now, not kicking up white caps until afternoon. All our families on the beach had such a fun and relaxing time playing, flat calm water let even the toddlers play at the water’s edge without worry or sand in the face. We are looking forward to diving all we can over the next week to take advantage of the automatically awesome photos our guides take while showing guests the reef. If you’re in Maui, come play with us!

Green Sea Turtles are our favorite, and there are now 2 new baby turtles on the reef, probably around 3 1/2 to 4 years old. Come see them for yourself, they can often be found near the point, at high tide or in the morning, feeding on the red algae growing near the surface.

One of these baby turtles is “Starburst”. She has an amazing shell pattern, and is really comfortable with snorkelers and divers around her. After the last series of waves and stormy weather, starburst has moved out from here hidden lair in the south reef shallows, out to “Joe’s garage” a little lava “slot” in the swim thru where a baby turtle can “park” and stay safe on the reef.



new baby turtle-no name yet!

another new baby turtle on the reef.

The other newest little one has yet to be named by one of our guests, but he stays close to shore, where he fells safe while getting used to reef life.




Do we really know if the are a boy or a girl? No! At this young of an age we can only guess, not accurately until they are anywhere form 15-20 years old or more. Turtles are slow growers, but as they age the “boy’s” tails grow longer, and the girls stay small. We have also noticed that older females tend to be thicker in the chest area than the boys. The older females will often be more comfortable “hanging out” with us underwater, while the males will shy away.

Spring water is here to bring the clear, deep ocean water and loads of new fish to our Hawaiian coral reef. Come play with us and explore Wailea Point and beyond!
