Explorer's Reef is a walk-through exhibit in Exhibits at SeaWorld San Diego. While it's not the best, it is also recommended.
Explorer’s Reef transforms SeaWorld's entrance into an interactive, undersea setting. A giant blue wave sculpture now spans the park's entrance, with coral-reef decor awaiting visitors as the enter. Under the reefs, you'll find four touch pools.
Both saltwater and freshwater, the 24,000-gallon touch pools will allow visitors to interact with bamboo sharks, skates, rays, horseshoe crabs, and more than 4,000 cleaner fish. Explorer's Reef opened officially on March 21, 2014 - the 50th anniversary of SeaWorld's opening.
