Singapore Oceanarium
4.6Google(33,805)One of Asia's most immersive aquariums, the Singapore Oceanarium on Sentosa Island takes you face-to-face with 800 species of marine life across a series of spectacular habitats — from a walk-through shark tunnel with predators gliding directly overhead to a cinema-sized open-ocean window where manta rays drift past in silence. You will move through a glowing jellyfish gallery that guests consistently describe as otherworldly — bigger than some entire aquariums on its own — before reaching the vast Open Ocean Habitat, where rays and sharks circle a tank that stops every visitor in their tracks. Add-on experiences including PADI dives and shark encounters are available at extra cost for those wanting to go deeper. Plan for a half-day: the venue is large, fully stroller- and wheelchair-accessible, and rewards unhurried exploration over two to four hours. Weekday mornings are the quietest; weekends and rainy days draw significant crowds. Guests rate the sheer scale and variety as the standout — nearly 100 reviewers highlight the underwater tunnels and massive tanks as the single best thing about the visit, and families consistently call it the best few hours they spent in Singapore. Book your tickets online in advance to skip the gate queue and secure the best available rate.
What guests love
- The jellyfish gallery — glowing, otherworldly, and unlike anything most visitors have seen
- The open-ocean manta ray tank: a cinema-sized window where you can watch rays and sharks glide past
- The walk-through shark tunnel with species swimming directly overhead
- Endless variety — visitors keep finding new rooms and species just when they think they've seen everything
- Wonderfully cool and spacious inside — a genuine escape from Singapore's heat
Worth knowing before you go
- Closed / restricted: Dolphins are kept on site; the dolphin area is optional and separate, but visitors who prefer not to see cetaceans in captivity can bypass it entirely.
- Book ahead: Tickets bought online in advance skip the gate queue and are slightly cheaper; walk-up tickets are available but queues can be long on busy days.
- Crowds: Weekends and rainy days bring very large crowds; some visitors found it hard to reach exhibits at all — weekday mornings are consistently the quietest.
- On foot: The venue is very large and fully walkable with strollers and wheelchairs; comfortable shoes matter, as a thorough visit covers a lot of ground.
- Cost: Entry is SGD 55 per adult at the gate; dolphin encounters, VIP tours, dives and official photos are all charged separately and add up quickly.
- Cost: On-site food and beverages are priced above what you'd pay outside, and the main restaurant is located roughly mid-way through the venue.
- Take care: Some third-party ticket websites have caused entry problems on arrival; checking that you hold a confirmed booking with a valid QR code before you go avoids delays.
- Facilities: Seating inside is limited — especially in front of the large open-ocean tank — and many visitors end up sitting on the floor to watch the manta rays.
