Seoul Science Center offers free permanent exhibitions, but parking costs KRW 150 per five minutes (1,800 per hour), up to 14,400 per day. Its official table lists 80% reductions for eligible disabled visitors and national merit recipients, and 50% for small/low-emission cars and qualifying multi-child card holders. Bring the required identity card, vehicle label or discount card. Galleries generally operate 09:30–17:30, closing on Mondays (Tuesday instead if Monday is a holiday) and designated holidays. The museum warns its car park is small, so use transit or nearby paid public parking when full. Address: 160 Hangeulbiseok-ro, Nowon-gu, Seoul; phone 02-970-4500.
