The Underwater World admission ticket, which costs S$22.90 for adults and S$14.60 for kids, already includes admission to the Dolphin Lagoon.
At certain schedules, they showcase their pink Indo-Pacific Humpback dolphins with a ‘Meet the Dolphins’ show. We watched the 3:30pm show. Other sessions are at 11am, 1:30pm and 5:30pm.
If seeing pink dolphins in action is your objective, this is the show for you. If, however, you’re fine with gray ones, I recommend that you check the Dolphin Show at Ocean Adventure in Subic instead.
Aside from that the trainers were better dressed in Subic (I mean they came in full swim gear, and not just shirts and shorts), the stunts were more interesting. There was a better interaction between the dolphins and the trainers.
Also, Ocean Adventure’s sea lion show was more entertaining than that of the Singapore Zoo (only a few kilometers from the Dolphin Lagoon, but requires a different admission ticket).
Once in Sentosa, getting to the Dolphin Lagoon is easy. Transportation via the Sentosa buses within the island is free and maps are available everywhere. That does not mean you can take as many maps as you want, though. Just take one for every group, and the trees will love you. 😉
