Located at the edge of Pier 39, the Aquarium of The Bay is home to more than 20,000 marine animals. Between river otters, seahorses, stingrays, and sharks, families can spend hours exploring the exhibits with the help of knowledgeable naturalists on stand-by. Ambient light sets the mood at Go With The Flow, a tank of jellyfish, while touch pools with anemones and starfish allure kids to the Touch the Bay section. Last but not least, end the visit with the playful river otters that await you at the gallery that houses four of them.
