Ancol Dreamland is part of a huge tourism resort on the Jakarta Bay that comprises multiple amusement parks, making it a must-visit for families on holiday in the capital city. While it isn’t likely you’ll be able to experience all of the different highlights in a single day, each entertainment feature are destinations on their own. The park was home to Indonesia’s own Sea World until 2014, but continues to attract crowds to its ‘Fantasy World’, full of endless thrill rides.
Considered the largest of its kind in Southeast Asia, the Ancol Dreamland tourism resort also features an international championship golf course, a hotel resort and Ocean Dream Samudra. The latter serves as an edutainment marine theme park much in place of the closed Sea World, featuring eight different regular shows including a dolphin show, together with saltwater and freshwater aquariums and even an adjoining bird park.
