This is at the top of our list. The San Diego Sea World was the first Sea World built. You can see first-hand various types of animals such as beluga whales, orca whales, pilot whales, polar bears, dolphins, penguins, manatees, and much more. Enjoy thrilling rides that are inspired by the ocean and watch entertaining and educational family-friendly shows. We suggest you upgrade your admission and get the 2-day pass. With this pass, you get a behind the scenes tour. The tour is different each day, but you may get a close-up look at a pilot whale and have the opportunity of petting a shark.
