A 918㎡ Youth Hub on the Hill of Sadang-ro 23-gil, Sadang Youth Center

918.33㎡, which became a youth hub in Sadang 3-dong after its 1991 construction

Sadang Youth Center is a facility newly built in February 1991. It has a total floor area of 918.33㎡ (277.8 pyeong) and consists of one basement level and three above-ground floors.

For accurate map searches and taxi destinations, enter “57-7, Sadang-ro 23-gil.”

The center is open from 09:00 to 21:00 Tuesday through Saturday, and from 09:00 to 18:00 on Sundays and public holidays. It is closed every Monday, so visitors planning to stop by after school should choose an evening from Tuesday to Saturday, while Sunday visits must be completed before 18:00.

Floor-by-floor options, from the basement-level “Chumdam” to the rooftop “Kkumbyeolnarae”

The basement level contains the multipurpose room “Chumdam 1,” music practice room “Soridam,” dance practice room “Chumdam 2,” coin karaoke room “Noraedam,” and lounge “Hyudam.” Chumdam 1 can be used free of charge by up to 20 young people for practice or study, and is equipped with speakers and full-length mirrors. However, adult use is limited to use under business agreements or network-based rentals.

The first-floor D·Dam is a space for programs, clubs, and events, while “Noreul Lab” is equipped with board games, Nintendo consoles, and arcade machines. “Meogeul Lab” includes a ramen shop for young people and a tea-and-coffee area for local residents, while “Sumeul Lab” is a rest area for groups. The second floor has the medium-sized lecture room “Kkumdam” and an office for guidance and inquiries. The third floor contains the youth creative space “Noldam” and “Haechannarae Room,” the space for the Youth Operating Committee.

Outdoor routes shaped by the rooftop observatory and 24-hour basketball court

The rooftop “Kkumbyeolnarae” is designated as an astronomical observation area and is connected with the center’s astronomy club, “Byeolsatang.” A rooftop remodeling project was announced in 2023, so visitors should not assume that the rooftop or observation events are always open. Check the website notices and confirm by telephone.

The outdoor youth basketball court is listed as operating 24 hours a day, year-round, under the responsibility of the Dongjak-gu Office Sports Policy Division. This means that the basketball court operates under separate rules after the center’s indoor operating hours end; indoor self-directed spaces and the outdoor court should not be regarded as having the same conditions.

Participation options for “Haechannarae” ages 14–24 and clubs for ages 9–24

The Youth Operating Committee “Haechannarae” is a facility participation body established under Article 4 of the Youth Activities Promotion Act. Approximately 14 young people aged 14–24 are recruited from January to March. Activities throughout the year include monthly regular meetings, facility and program monitoring, meetings with the head of the institution, and program planning. Benefits listed for participants include e-Youth volunteer certificates, appointment certificates and committee member IDs, and free use of facilities such as meeting rooms, party rooms, and the coin karaoke room.

Specialized clubs are open to at least three young people aged 9–24 and operate from January through December in areas such as play planning, sports, and shared cooking. The fields listed for cultural arts clubs include dance, bands, vocals, traditional Korean music, cheerleading, and theater. Recruitment periods and interview and application procedures may differ for both activities, so rather than expecting a facility that can simply be entered and used freely, visitors should check the recruitment notice for the relevant year.

Preparing for vehicles with a five-car parking lot and a rate of 300 won per 10 minutes

The center’s parking lot is listed as accommodating five cars during both the day and night, so visitors should not assume that parking will be readily available. Parking use may be restricted depending on the internal schedule. Parking inquiries should be made at the second-floor office or by calling 02-595-0231.

According to a 2021 notice, the daytime parking fee for vehicles not using the center was 300 won per 10 minutes, while a nighttime monthly pass cost 44,000 won for the period from the first to the last day of each month, covering 18:00–09:00. Visitors using the center were informed that free parking was available for the duration of their use, but current fees and the conditions for free parking may have changed, so telephone confirmation is necessary before setting out.

• Parking capacity: 5 cars
• Daytime rate in a past notice: 300 won per 10 minutes
• Nighttime monthly pass in a past notice: 44,000 won per month
• Nighttime monthly pass hours: 18:00–09:00

Barrier-free facilities for wheelchair and stroller access, with checks to make before visiting

The Korea Tourism Organization’s barrier-free travel information lists the facility as having an accessible restroom, an elevator for people with disabilities, designated accessible parking spaces, a main entrance without level differences, wheelchair rental, a nursing room, and stroller rental. It also indicates convenience services for people with visual or hearing impairments, as well as access by subway and low-floor buses.

However, the publicly available information does not specify the number of wheelchairs available for rental, the operating hours for the nursing room or stroller rental, or the actual languages provided for foreign-language guidance. If you need assistive-device rental or an accessible route for a companion, it is best to describe the support you need specifically and confirm it in advance by calling the main number, 02-595-0231~3.
