Gelanggang Samudra is an animal-based theme park, which is one of the attractions at the Taman Impian Jaya Ancol recreation park located in Jakarta, Indonesia. Ancol itself is a popular recreation park among Indonesians, located within the shore of the Jakarta bay, north of the city. However, being an aging attraction, it seems that Gelanggang Samudra is not as popular as other attractions such as the Sea World, which is located next to Gelanggang Samudra, the Atlantis Water Adventure and the more thrilling Dunia Fantasi.
For me, I found out that the Gelanggang Samudra is more educative to the kids. There are three animal shows, namely dolphin show, sealion show and other various animals show, staged several times a day, and each show is being conducted at different times, to ensure that we can attend all the three shows at the shortest time possible. There's also one 4D show which we can attend, and the kids also can have unlimited access to some rides, such as bumper car and balloon ride.
The MCs and the trainers of the animals who are staging the shows are also very professional in bringing up the shows with some jokes here and there. However, the shows were being presented in bahasa Indonesia, so foreign tourists might have difficulties in understanding them although they can still enjoy the animals' talents and capabilities during the show. That might be the reason why this attraction might still be appealing for domestic tourists, but not for foreign tourists.
On top of Ancol's entrance fee (12,000 rupiahs per person and 12,000 rupiahs per car), we needed to pay the Gelanggang Samudra's entrance fee of 60,000 rupiahs per person. That would set you back around 72,000 rupiahs (around SGD $10 or USD $7.79) per person, which is quite reasonable. The best way to reach Ancol is to drive your own car or take a cab. Alternatively, you can also take the TransJakarta busway.
