Stop by and experience the wonders of local marine life!
Located in beautiful downtown Manhattan Beach, California, the Roundhouse has undergone a recent revitalization through a $4 million capital project spearheaded by the Harrison Greenberg Foundation. The new Roundhouse Aquarium educates and inspires more than 300,000 visitors every year. It is managed and operated by the nonprofit oceanic and environmental organization Oceanographic Teaching Stations, Inc. (OTS), whose mission is to connect and engage visitors and students to the oceans through hands-on interactive experiences with marine life and habitats of southern California, and to inspire them to become good stewards of our environment.
OTS’ programs at the Roundhouse Aquarium promote the study of the oceans, tidelands and beaches of Southern California through a wide slate of science-based and standards-aligned education programs with its immersive and engaging exhibits of a diverse array of marine life. More than 100 marine animals from Southern California’s waters live at the aquarium, many are native to its local waters in the Santa Monica Bay. Notable wildlife include moon jellies, sharks, octopus, sheephead, moray eels, lobsters, and more – as well as a touch tank with sea stars, sea cucumbers, sea urchins and sea snails.
The aquarium prides itself on being family oriented. It’s a great place for kids to take their parents!
