Hawaiian monk seals
Meet rescued seals that cannot return to the wild and learn why this native species needs careful protection.

Meet monk seals, giant clams, living corals, and reef fish in a compact shoreline aquarium with a century of Hawaiian marine research behind it.
Small, focused, memorable
Waikīkī Aquarium is a calm, approachable introduction to Hawaiʻi's marine world. Its tanks focus on Pacific habitats, unusual reef animals, coral conservation, and the species that make the islands' ocean ecosystem distinct.
The aquarium sits directly on the shoreline across from Kapiʻolani Park, close enough to combine with a beach walk, picnic, or zoo visit. Indoors, galleries move from tiny seahorses to large reef displays. Outside, the Hawaiian monk seal habitat is a first-visit priority.
This is not a giant entertainment complex. Its strength is thoughtful interpretation, living coral, and a manageable scale that works especially well for families, curious adults, and visitors fitting a meaningful stop into a Waikiki day.
Simple walk-up admission
The aquarium currently sells admission at the front desk. Paid admission includes access to a free mobile audio guide, so bring a charged phone and headphones if you want the extra interpretation.
First-visit priorities
Six exhibits give the aquarium a clear route from Hawaiian wildlife to coral science and the wider Pacific.
Meet rescued seals that cannot return to the wild and learn why this native species needs careful protection.
Follow coral communities from shallow water to deeper reef zones while watching fish move through changing habitats.
See vividly colored living clams and discover the close relationship between sunlight, algae, and reef life.
Learn how aquarium specialists cultivate coral for research, conservation, and responsible exchange with other institutions.
Look closely for seahorses, seadragons, and pipefish whose body shapes make camouflage an art form.
A large barrier reef habitat gathers live coral, giant clams, and more than one hundred fish species.

Why it stands out
The collection is shaped by place. Waikīkī Aquarium is known for living coral, reef organisms, and the science of sustaining delicate marine communities. The result feels closer to a marine field station than a theme park.
Look closer

A rare opportunity to see a Hawaiian monk seal while learning how rescue and long-term care support the species.

Brilliant mantle patterns make these reef giants some of the collection's most photogenic residents.

Living coral turns conservation research into something visible, detailed, and immediately understandable.
A relaxed two-hour route
Start with the indoor galleries, slow down for the major reef tanks, then finish outside before continuing along the shoreline.
Begin with the smaller animals, then follow the reef displays from shallow water into deeper communities.
Spend the middle of the visit with the aquarium's strongest coral and biodiversity exhibits.
Finish at the outdoor habitat, then step outside for the oceanfront walk toward Kaimana Beach or Waikiki.
Practical visitor guide
Exact location
2777 Kalākaua Avenue, Honolulu, HI 96815. The entrance faces the oceanfront boulevard across from Kapiʻolani Park.
Follow Kalākaua Avenue toward Kapiʻolani Park. The aquarium is near the quieter Diamond Head end of the shoreline.
Public buses run along nearby streets, while rideshare drop-off avoids the uncertainty of finding a parking space.
Street and public parking in this part of Waikiki can fill quickly. Read posted signs and do not rely on immediate availability.

More than a century by the sea
Founded in 1904, Waikīkī Aquarium is the second-oldest public aquarium in the United States. The University of Hawaiʻi at Mānoa has administered it since 1919.
Its shoreline location beside a living reef has shaped a deep focus on tropical Pacific marine life. The aquarium now cares for more than 3,500 organisms representing over 500 species, while its coral work supports research and aquariums far beyond Hawaiʻi.
Quick answers
Yes if you value Hawaiian marine life, living coral, conservation, and a calm experience that fits easily into a Waikiki day. Visitors expecting a huge all-day aquarium should know that this is a compact, education-focused institution.
About 90 minutes is enough for a comfortable first visit. Allow two hours if you like reading interpretation, using the audio guide, or watching the reef tanks slowly.
The official admission page currently directs visitors to buy tickets at the front desk when they arrive. Check the official site before visiting in case the process changes.
Yes. The compact layout, colorful tanks, small-animal exhibits, and monk seal habitat work well for families. Strollers and excited viewing areas can feel busier at peak times.
Yes. It is on Kalākaua Avenue at the Diamond Head end of Waikiki, across from Kapiʻolani Park. The walk is especially pleasant when paired with the shoreline.
Kapiʻolani Park, Kaimana Beach, and a coastal walk are the easiest pairings. Honolulu Zoo is nearby but turns the day into a longer family itinerary.
