Just beyond the shoreline of Waikiki, tucked beside the golden sands of Kaimana Beach and in the shadow of Lē‘ahi (Diamond Head), you’ll find one of O‘ahu’s most iconic destinations, the Waikiki Aquarium. This oceanfront gem is more than just a fun rainy-day activity or a great way to entertain the kids (though it’s definitely both!). Here’s why you should add this one-of-a-kind experience to your itinerary while staying at Prince Waikiki.
Founded in 1904, the Waikiki Aquarium is the second-oldest public aquarium in the United States. Today, it’s home to more than 3,500 marine animals representing over 490 species, many of which are native to Hawaiian waters and can’t be found anywhere else in the world!
Developed initially to showcase the beauty of Hawaii’s coral reefs, the aquarium has grown into a globally recognized hub for conservation, education, and marine research. Operated by the University of Hawaii since 1919, it continues to evolve, blending cutting-edge exhibits, hands-on programs, and environmental stewardship while staying true to its original mission of inspiring understanding and care for our oceans.
With a range of unique exhibits and a stunning location beside a living coral reef, the Waikiki Aquarium brings the wonders of the Pacific Ocean to life. As you wander through the galleries, you’ll come face-to-face with native Hawaiian species like the colorful humuhumunukunukuāpua‘a (reef triggerfish), graceful seahorses, curious octopuses, dazzling jellyfish, and even the endangered Hawaiian monk seal.
The Amazing Adaptations exhibit introduces visitors to the many ways ocean animals have evolved to thrive in their habitats, while the Hunters on the Reef gallery showcases top predators of the sea like groupers and zebra sharks. For a peek into ancient Hawaiian aquaculture, the Ocean Aquaculture exhibit highlights the moi fish, once raised exclusively for Hawaiian royalty. Kids (and the young at heart!) will especially love the Jet Set and Diversity and Adaptations exhibits, which both offer colorful, interactive displays about unique animal behaviors.
Want to get even closer to the magic? The aquarium hosts a range of interactive activities and educational programs throughout the year, many of which are perfect for families. Join Behind the Scenes tours to see what goes into caring for thousands of aquatic species, or sign up for special events like Aquarium After Dark, which offers visitors an after-hours glimpse into the secret lives of nocturnal reef creatures.
Explore their calendar for educational events happening throughout the year. And after your visit, continue learning about Hawaii’s marine life through their free virtual experiences, featuring online lectures, Q&As, and more!
At the heart of the Waikiki Aquarium’s mission is a deep commitment to conservation. From conducting aquatic research to leading beach cleanups and animal rescue programs, they play a vital role in preserving local marine ecosystems. This passion for caring for the environment aligns with Prince Waikiki’s own commitment to eco-conscious hospitality. We’re proud to support initiatives that help sustain the natural beauty of our island home for future generations.
