The Monterey Bay Aquarium is a window to the world’s oceans and features over 200 marine life exhibits. There’s a lot to see and do, so set aside about 3-4 hours to explore this world-famous Aquarium on Cannery Row. The Monterey Bay Aquarium also offers guides tours, shows, animal encounters and feedings, and a café, so you may need a few more hours to experience it all.
