If you have been searching for S.E.A. Aquarium tickets and getting confused, here is the short version: it grew up and changed its name. The Singapore Oceanarium opened on 24 July 2025 at Resorts World Sentosa, a full revamp and expansion of the old aquarium at 8 Sentosa Gateway. It has quickly become one of the default family days out in Singapore, so here is everything you need before you go.
The Oceanarium is the successor to the S.E.A. Aquarium at Resorts World Sentosa, reopened in July 2025 after a major revamp and expansion. Same address on Sentosa, much bigger ambition, with the marine life galleries rebuilt and extended. If your last visit was in the S.E.A. Aquarium days, it is a genuinely different outing now, which is exactly why the entry price runs higher than the old aquarium's.
Pricing is split by residency, and the from-prices move with the date you pick. Singapore residents: adults (13 to 59) from $42, children (4 to 12) from $35, seniors (60 and up) from $35. Non-residents: adults from $50, children from $39, seniors from $39. Kids under 4 fall outside the ticketed age bands. Booking online ahead of your visit is the way to lock the lower end of those ranges, since peak dates price higher.
The Oceanarium sits at 8 Sentosa Gateway in Resorts World Sentosa. Easiest route: NorthEast Line or Circle Line to HarbourFront, head up to VivoCity Level 3, then take the Sentosa Express one stop to Waterfront station. The boardwalk from VivoCity is a pleasant free-entry walk too. Sentosa usually has something else on to stack your day with, like the food festivals on Siloso Beach that we cover every year, including Sentosa GrillFest and its free taco runs.
ยท Book online for the cheapest dates. Walk-up pricing on peak days is the worst deal.
ยท Weekday mornings are the quiet window, especially outside school holidays.
ยท Pair it with whatever festival is running on Siloso Beach to get more out of the island trip.
