Waikiki Aquarium

I was super impressed by this aquarium. The Waikiki Aquarium is an aquarium was founded in 1904. The aquarium is the second-oldest still-operating public aquarium in the United States, after the New York Aquarium. And while the aquarium is relatively small compared to many of the national aquariums around the world, what it did well was educate.  There's an online audio guide that's very informative.  I learned a lot about the waters around Hawaii from the audio guide.
