Singapore Oceanarium one-day tickets start at $55 for an adult (ages 13 to 59) and $43 for a child (4 to 12) or senior (60 and above), the from-prices Resorts World Sentosa lists on its own site. It opens 10am to 8pm on a normal day and sits at 24 Sentosa Gateway. If you have been searching for S.E.A. Aquarium tickets and getting confused, it is the same place: the aquarium was rebuilt and reopened as the Singapore Oceanarium on 24 July 2025.
Resorts World Sentosa lists the one-day ticket as from $55 for an adult (ages 13 to 59), from $43 for a child (ages 4 to 12) and from $43 for a senior (60 and above). Read the word from carefully: these are floor prices, and what you actually pay moves with the date you pick, with peak dates sitting at the top of the range. Time-entry tickets are required during peak periods, so on busy days you are booking a slot rather than just a date. Children under 4 fall outside the ticketed age bands entirely. Prices here were checked against the RWS site on 14 August 2026, and they do change, so treat them as the starting point rather than a promise.
The Oceanarium runs 10am to 8pm on a normal day, with last admission at 8pm. Pier Adventure, the suspended walkway, runs a shorter 11am to 7pm. The detail most guides leave out is that it closes early on a scattered set of dates, and turning up at 5pm on one of them means a wasted trip across the island. Off the Oceanarium's own operating-hours calendar, checked 14 August 2026, it closes at 4pm on 20 and 22 August, on 2, 3, 4, 10, 18 and 20 September, on 15, 18, 29 and 31 October, and on 19, 20, 28 and 29 November 2026. There is one 6pm close, on 19 September. Hours are subject to change, so glance at their calendar the day before you go.
Two things, as of 14 August 2026. The Marine Mammal Habitat viewing panel is temporarily closed until further notice, and Life in the Deep, part of The Abyss, is closed for maintenance. If the dolphins are your reason for going, check that the panel has reopened before you book.
The Oceanarium is laid out as a route rather than a room of tanks. You move through In the Beginning, At the Surface, Sunlight, Into the Deep, The Abyss and A New Horizon, starting at the first fishes, passing Singapore's own coastlines and the interactive habitat there, dropping to the seafloor and the shipwrecks, then surfacing on what the ocean is up against. That sequencing is the real change from the old S.E.A. Aquarium, which was a set of habitats to look at rather than a story to walk through. It is also why the ticket costs more than the aquarium's did.
The Oceanarium sits at 24 Sentosa Gateway, Sentosa Island, Singapore 098137, inside Resorts World Sentosa. Easiest route: NorthEast Line or Circle Line to HarbourFront, up to VivoCity Level 3, then the Sentosa Express one stop to Waterfront. Walking in over the Sentosa Boardwalk from VivoCity is free and open 24 hours, which is the cheapest way onto the island if you are not in a rush. Driving, park at B1 East Car Park; the recommended drop-off is the B1 Casino entrance. Sentosa usually has something else running to stack your day with, like Sentosa GrillFest and its free taco runs.
Three worth knowing. Twilight Waves is an admission-from-4pm ticket bundled with a $5 retail voucher and a $5 meal voucher, neither with a minimum spend, which suits anyone treating this as an evening instead of a full day out. The Season Pass covers unlimited visits plus birthday-month perks and a one-time Animal Spotlight: Sea Jellies session that otherwise goes for $28, so it pays off quickly if you have kids who will ask to come back. And there are bundles pairing the Oceanarium with Adventure Cove Waterpark, or a combined pass with Universal Studios Singapore, if you are doing more than one RWS attraction in the same week.
· Check the operating-hours calendar before you go. The 4pm closures are scattered and easy to miss.
· Book online and off-peak. The from-prices only apply on the quieter dates.
· Walk in over the Boardwalk from VivoCity if you are counting cents. It is free and open 24 hours.
· Twilight Waves is the value pick if you are happy starting at 4pm.
Resorts World Sentosa lists one-day tickets from $55 for adults aged 13 to 59, and from $43 for children aged 4 to 12 and seniors aged 60 and above. These are from-prices that rise on peak dates, so the exact amount depends on the day you book. Checked 14 August 2026.
Not under that name. The S.E.A. Aquarium at Resorts World Sentosa was rebuilt and reopened as the Singapore Oceanarium on 24 July 2025, on the same Sentosa site. If you are searching for S.E.A. Aquarium tickets, the Oceanarium is what you are looking for.
10am to 8pm on a normal day, with last admission at 8pm. It closes at 4pm on a scattered list of dates, including 20 and 22 August 2026, and at 6pm on 19 September 2026. Check the Oceanarium's own operating-hours calendar before travelling.
24 Sentosa Gateway, Sentosa Island, Singapore 098137, inside Resorts World Sentosa. Take the NorthEast or Circle Line to HarbourFront, go up to VivoCity Level 3, then ride the Sentosa Express one stop to Waterfront.
The ticketed age bands start at 4, so under-4s are not covered by the child ticket. Resorts World Sentosa does not list a price for them, so check with the Oceanarium directly if you are bringing a toddler.
As of 14 August 2026 the Marine Mammal Habitat viewing panel is temporarily closed until further notice, and Life in the Deep, in The Abyss zone, is closed for maintenance. The rest of the route is open.
