Waikiki Aquarium

Opened in 1904, this is the second oldest aquarium in America, located on the shoreline of Waikiki Beach next to a living reef and across from Kapiolani Park.  Its original owners, the Honolulu Rapid Transit and Land Company, used it to entice its passengers to ride to the end of its trolley line in Kapi‘olani Park, where the Aquarium was located.  Since 1919, the Aquarium has been administered by the University of Hawaii. Nowadays, the Aquarium showcases more than 500 marine species, and maintains more than 3,000 marine specimens.
