Inside SeaWorld San Diego at 500 Sea World Drive, the Nautilus Amphitheater is an open-air stadium in the 92109 zip code that hosts live entertainment throughout the theme park's operating season. The venue has served as a performance space since the park's early decades, with concert history stretching back to a 1988 appearance by jazz legends Stan Getz and George Shearing. Today the amphitheater anchors SeaWorld's seasonal programming, including the Summer Spectacular lineup that has featured the BMX Blast stunt show with professional riders performing tricks set to live music. The Nautilus sits within the broader SeaWorld San Diego campus, which celebrated its 60th anniversary in 2024 and draws millions of visitors annually to its marine exhibits, roller coasters, and animal encounters. Stadium seating provides clear sightlines from multiple angles, and the open-air design lets audiences enjoy San Diego's coastal climate during evening performances. SeaWorld's summer concert series runs on Saturday nights and has hosted acts ranging from Baby Bash to Ginuwine and the I Love the 90s Tour. The amphitheater is wheelchair accessible, with accessible entrance points, parking, and restrooms all available within the park. Group event bookings can use the adjacent Nautilus Pavilion, a glass-enclosed structure next to Mission Bay with a reception capacity of 1,200 and banquet seating for 600. Visitors spending a full day in the area can pair a SeaWorld visit with a round at Mission Bay Golf Course and Practice Center, one of the few night-lit courses in the region. Park admission is required for amphitheater access, and reserved concert seating can be purchased separately through SeaWorld's website.
