The Singapore Oceanarium is Resorts World Sentosa’s aquarium, which opened on 24 July 2025 in place of the old S.E.A. Aquarium, at 24 Sentosa Gateway. It tells the story of the ocean through 22 zones grouped into six chapters, from the evolution of fish to Singapore’s own coast, the Open Ocean habitat with sharks and manta rays, the deep sea and a closing conservation gallery. As of October 2026, tickets start from S$55 for adults (13 to 59) and from S$43 for children aged 4 to 12 and seniors aged 60 and above. Opening hours vary by day, so check the official calendar before you go.
Few places in Singapore make children go quiet quite like a wall of blue water with a manta ray gliding past. Here’s what you’ll find, and how to keep the bill sensible.

Worked example: a family of four
Two adults and two children aged 4 to 12 at the “from” prices: 2 × S$55 = S$110, plus 2 × S$43 = S$86, making S$196. Add Sentosa transport and lunch on top. If you plan to visit Universal Studios on the same trip, price a multi-attraction pass before buying separate tickets.
How to plan the visit
- Check the operating-hours calendar on the Singapore Oceanarium site; it lists closures and early closings by date.
- Buy online in advance, especially for weekends and school holidays, when timed entry applies.
- Look up the day’s feeding and talk times so you reach the Open Ocean habitat at the right moment.
- Get to Resorts World Sentosa by the Sentosa Express, bus, car or the Sentosa Boardwalk.
The WahLiao Verdict
Book online for a weekday morning, check the calendar for closures, and make the Open Ocean habitat your unhurried centrepiece. Skip the premium add-ons on a first visit; the main route is the show. If you are doing Universal Studios too, price a combined pass first, and if you live here and love sea creatures, compare a season pass against two single visits.
Questions people ask
Is the Singapore Oceanarium the same as S.E.A. Aquarium?

How much is a ticket?
From S$55 for adults and from S$43 for children aged 4 to 12 and seniors aged 60 and above, as of October 2026.
Can I see the dolphins?
The Oceanarium has Indo-Pacific bottlenose dolphins and sells Dolphin Moments interactions, but its site says the Marine Mammal Habitat viewing panel is temporarily closed. Check before you go if dolphins are the main draw.

RWS does not publish a set time. Most families will want a few hours to walk the 22 zones at a gentle pace and catch a feeding session.
