There are no seaquariums or dolphinariums in Aruba. Our sister island, Curacao, does have a seaquarium called Cucacao Sea Aquarium where they used to offer swimming with dolphins as an attraction. However, this is not something that seems to be promoted any more on the internet. In Aruba, there has been a lot of resistance to organizations who have contemplated keeping dolphins in captivity for public entertainment, which explains the lack of such establishments.
