Discover the wonders of the Pacific at the Waikiki Aquarium, the second oldest public aquarium in the United States, nestled along the picturesque Waikiki shoreline. Founded in 1904, this compact yet captivating "small gem of the Pacific" is home to over 3,500 marine animals from 500 species, alongside vibrant marine plants, making it a crucial center for the understanding, appreciation, and conservation of Hawaii's unique aquatic ecosystems.
Wander through 13 distinct display areas, including the impressive Living Reef exhibit, showcasing over 100 species of fish and 200 types of coral in a 60,000-gallon saltwater tank. Marvel at the rare and endangered Hawaiian Monk Seals, Maka onaona and Ho'ailona, in their dedicated habitat, or witness the iridescent beauty of Giant Clams, some specimens over three feet long. The Amazing Adaptations gallery introduces visitors to exotic seahorses, seadragons, and pipefishes, while the Edge of the Reef Touch Pool offers a hands-on experience with sea stars, anemones, and sea cucumbers. Don't miss the mesmerizing Jellyfish Gallery, where graceful moon jellies and upside-down jellyfish captivate with their ethereal movements.
More than just an exhibit space, the Waikiki Aquarium is a dynamic hub for marine research and conservation, designated a Coastal Ecosystem Learning Center. It actively engages visitors of all ages with interactive programs, daily animal feedings, and educational initiatives focused on protecting marine life, including Hawaiian Green Sea Turtles and its pioneering coral propagation program. A visit here offers not only stunning photographic opportunities but also a deeper connection to the health and beauty of the ocean.

The Waikiki Aquarium boasts a rich history, established on March 19, 1904, by the Honolulu Rapid Transit and Land Company. Initially known as the Honolulu Aquarium, its primary purpose was to encourage trolley riders to travel to the end of the line at Queen Kapiʻolani Park by showcasing the mesmerizing reef life of the islands. Since 1919, it has been an institution of the University of Hawaiʻi at Mānoa, evolving into a globally recognized center for conservation, education, and marine research. It holds the distinction of being the second-oldest continuously operating public aquarium in the United States. Over its long history, the aquarium has achieved several "firsts," including the first displays of living Pacific corals in the U.S. in 1978 and the first in the world to produce viable Nautilus embryos. Notable exhibits like the Giant Clam display in 1979 and the blacktip reef sharks around 1957 also marked significant milestones in its development. In 1955, the Aquarium relocated to its present 2.35-acre site, continuing its mission to inspire marine appreciation and conservation.
