Oktokki Uju Center in Incheon is an exhibition and activity space that runs space displays, children's hands-on facilities, and outdoor rides together. Visitors can see rocket, airplane, and space station exhibits, then use the boats, four-season sledding, and Dinosaur Forest after entry. About six indoor activity machines are on the first floor, and going through the exhibition halls and rides takes two to three hours. There are a fair number of bugs outdoors, so bring mosquito repellent.
