Shamu CloseUp is a walk-through exhibit in Exhibits at SeaWorld San Diego. While it's not the best, it is also recommended.
An exhibit that offers both above water and underwater views of the park's killer whales outside of shows. Go downstairs for a massive acrylic panel that allows for a great underwater view of the animals! The park's Dine With Shamu program is also held here and it is possible to watch the killer whales in training from Shamu CloseUp without having to purchase the Dine With Shamu experience.
