Experience Kailua Bay's Spinner Dolphins!

Kailua Bay, located on the picturesque Kona coast of Big Island Hawai’i, is a vibrant marine ecosystem renowned for its rich biodiversity.

Among its most enchanting residents are the playful Spinner Dolphins, known for their acrobatic displays and energetic spins as they leap from the water.

These dolphins are often spotted in pods, showcasing their social nature and close-knit family bonds. They typically frequent the bay during the early morning hours, making it a prime time for wildlife enthusiasts and tourists to witness their lively antics.

The warm, clear waters of Kailua Bay provide an ideal habitat for these marine mammals, offering abundant food sources such as fish and squid. Conservation efforts have been implemented to protect their natural environment, ensuring that future generations can enjoy the sight of these magnificent creatures.

Visitors to Kailua Bay can take guided tours or participate in eco-friendly activities to learn more about Spinner Dolphins and their habitat. Observing these dolphins in their natural setting is not only a thrilling experience but also a reminder of the importance of preserving our oceans and marine life.

    Amazing rental place!

    The owner and employees are extremely knowledgeable with a great attitude as well. The area is fantastic for paddle boarding and kayaking, as soon as we hit the water we saw a huge pod of spinner dolphins which were accompanied by humpback whales shortly after! 10/10, Incredible experience!

    We rented here twice!

    Dolphins!!! Paddle boards one day and kayak another. Both were excellent experiences with the owner who was friendly and helpful. We immediately saw dolphins after a 10 minute kayak to the spot she pointed us to. It was incredible to see them up close.

    Also great swag here!

    Thank you again for such a great experience!

    We were the first customers of the day and we were taken such good care of. We had to fill out our forms and as we did they started to get busy but she made sure to get us out on the water before she finished up with anyone else, which I really appreciated. I would’ve waited patiently but the fact she told the other customers “Let me get these guys since they were here first” Was so nice. The double kayak was awesome and the prices were beyond reasonable. Thank you again for such a great experience!

    Great watersports rental outfit

    They offer online booking, which is useful if you plan ahead or visit during peak times. They advertise the “lowest rates in town,” and after walking around, I found this to be true. They are located across from Kamakahonu Beach, which is a great place to test their equipment before taking it out into the bay.

    We were given a detailed safety briefing, launch location information, and several tips to make our time on the water more enjoyable. We rented rigid paddleboards (not the inflatable kind), which were great for the early morning conditions we encountered in the bay. Other than some minor wear and tear typical of any rental gear, everything was well-maintained. Their gear also appeared more robust than the more anemic-looking gear we found at other rental outfits.

    A memory I will never forget

    We decided to rent out some kayaks for our party of 9, although some of the party were a little apprehensive. When we got here, the lady who runs it (I didn’t catch her name), went through all the safety checks and told us about the expected conductions of the waters, this made 5 of the 9 decide against it, which was a wise decision as the waters were choppy as she explained and this would have given a few people motion sickness and have been scary for the smallest member of our party. She prioritised our experience and safety over business sales and this speaks a thousand words about how much she cares about her clients. The safety briefings, the actual kayak itself were all perfect, and we were lucky enough to be joined in the waters by around 15-20 spinner dolphins. Of course you need to stay away from them but seeing them jump in and out of the waters in their natural environment was incredible, a memory I will never forget. She also filled us with local knowledge of the Outrigger races, the history of the queens and kings of the island, which made our transaction even more special. Thank you for everything ♥️

    Awesome staff

    What I liked is that this shop is so close to the water, right across from Kailua bay. The staff is super friendly and helpful and they have stand up paddle boards, e-bikes,surfboards,beach equipment, snorkel and scuba rentals, all new looking and reasonably priced. The snorkel gear worked great. I would definitely recommend this place.

    Great rentals and staff

    My family and I visited Ali’i Adventures day before yesterday and I’m glad we did! Sherry was so helpful and was able to get us all properly fitted gear and a couple of paddle boards. She even told us about a few snorkel spots to hit up! I highly recommend this shop. They’re right across the street from the water so we were able to rent the board and paddle out right away.
