Idea Island, inside Chuncheon's Idea Library, is a creative activity space for the 'tween' age group. The official rules restrict use to Chuncheon residents in fourth through sixth grade or first and second year of middle school. Parents and people outside that age group may not accompany participants into the space.

Individual sessions run Monday–Thursday and Saturday–Sunday at 09:30–11:30, 13:00–15:00 and 15:30–17:30, with a capacity of 20 per session. Registration is first-come at the third-floor information desk. Students need full library membership verification and a physical membership card. The library's regular closed day is Friday.

Local primary schools may apply for group visits in the weekday morning session from the second semester of 2026. Since guardians cannot enter with the child, ask staff about drop-off and collection arrangements. Individual enquiries: 033-245-5509.
