Jeju Byeolbit Nuri Park sits in front of Nanta Hotel near Jeju City and runs 4D screenings and astronomical observation. In the planetarium, visitors watch a presentation on the formation of the Earth, and on clear nights they can examine constellations through a telescope. The 4D screening lasts about five minutes, and entry to the observation area closes one hour and thirty minutes before the end. On cloudy days, the telescope cannot be used to see stars.
