Waikiki Aquarium

The Waikiki Aquarium showcases Pacific marine life in Hawaii's third-oldest public aquarium, operating since 1904. This compact facility focuses on Hawaiian and tropical Pacific species rather than competing with larger mainland aquariums. You'll encounter Hawaiian monk seals, vibrant reef fish, mesmerizing jellyfish galleries, and outdoor exhibits housing giant clams and sea turtles. The aquarium suits families with young children, marine biology enthusiasts, and visitors seeking shelter during Waikiki's afternoon rain showers. Plan 90 minutes to two hours for your complete visit. Exhibits spread across flat, accessible terrain accommodating strollers and wheelchairs easily. Parking fills the small on-site lot by 10am on weekends and during summer months. Street parking along Kalakaua Avenue provides alternatives, requiring quarters for two-hour meters. The facility sits directly across from Kapiolani Park, allowing families to combine aquarium visits with beach outings or picnic lunches. Adult admission runs $12, children pay $5. The aquarium opens daily from 9am to 4:30pm, with optimal viewing between 10am and noon when crowds thin and fish respond actively during scheduled feeding sessions. Pack a light jacket for air-conditioned indoor exhibits, especially during warm afternoons when temperature differences feel pronounced. Comfortable walking shoes work best for outdoor concrete pathways. You'll experience some sun exposure moving between buildings, though covered walkways provide adequate shade. The gift shop features locally crafted items and educational materials highlighting Hawaiian marine conservation programs, making it worth browsing before departure.
