It is located in Sibolangit, about 20 minutes before Berastagi on the road Medan - Berastagi, so about 1 hour from Medan. It is at a slightly lower altitude than Berastagi, but much cooler than Medan (though still hot in the midday Sun).
There are some bumper cars (aka dodgems), a rollercoaster , a big ferris wheel, a flat train, a water inner tube slide, about 7 or so other fairground type rides such as a tree house, then in the indoor area (a nicely designed fairy tale castle) there is a very good dimsum restaurant and some arcade machines such as the basketball game.
