A Look Back: History of the Waikīkī Aquarium

The Waikīkī Aquarium is more than just a place to see beautiful marine life—it’s a piece of history. Opened in 1904, it’s the second oldest public aquarium in the United States. Originally operated by the Honolulu Rapid Transit and Land Company, the aquarium was meant to draw visitors to the newly developed Waikīkī area.

Over the years, the aquarium has evolved into a leader in marine research and conservation. Since 1919, it has been managed by the University of Hawaiʻi, giving it a strong educational focus. It was also the first aquarium to keep and breed many Pacific marine species, including the endangered Hawaiian monk seal. The aquarium has evolved to showcase Hawaiian marine communities, illustrating the distinct marine life and ecological features of the region.

The aquarium sits right on the shoreline, allowing it to use fresh seawater directly from the ocean. This unique feature keeps its coral reef exhibits healthy and thriving. Thanks to its ongoing scientific work and community outreach, the Waikīkī Aquarium is a respected voice in marine education across the Pacific.

Easy to Access and Close to Everything

Since the aquarium is just a short walk from most Waikīkī hotels, you won’t need to stress about transportation. If you’re driving, there is a small lot in front of the aquarium, as well as metered parking available right outside the entrance on Kalākaua Avenue and around Kapiʻolani Park. It usually isn’t too tough to find a spot, especially in the morning. Try arriving right when the Waikīkī Aquarium hours begin at 9 a.m. to beat the crowds.
