Namchang Valley, where six valleys converge beneath 626-meter Ibanmsan Mountain
Namchang Valley is located in Sinseong-ri, Bukha-myeon, Jangseong-gun, Jeollanam-do, and belongs to the Namchang District of Naejangsan National Park. Situated at the foot of 626-meter Ibanmsan Mountain, it is described as a place where six branches of valleys converge and flow together, making it more of a destination for walking forest trails and valleys than simply a spot for water play.
The address provided in Jangseong-gun tourism information is 399 Namchang-ro, Bukha-myeon, Jangseong-gun, Jeollanam-do (Ibanmsanseong Fortress Promotion Center). The official operating hours and regular closing days of Namchang Valley have not been confirmed, and it is safest to state only that no separately charged admission fee has been identified in the available information.
Why Ibanmsanseong Fortress from the Samhan period became today’s trekking destination
The Namchang Valley trekking route continues to Ibanmsanseong Fortress. Ibanmsanseong Fortress is described as having been built during the Samhan period, with walls approximately 3 meters high and 15 kilometers long in total.
Wetlands have formed around the fortress, and endangered species such as flying squirrels are known to inhabit the area. Thus, the nature around the trail is both a backdrop for the walk and something to be protected. Since parts of the inland wetland are designated as special protection zones and closed to entry, visitors must not enter the waterside or wetland areas on their own.
About one hour from Namchang Parking Lot to Ibanmsanseong Fortress
Visitors arriving by car can use Namchang Parking Lot as their starting point. The parking lot is indicated around San 25, Sinseong-ri, Bukha-myeon, Jangseong-gun, Jeollanam-do, but the number of available spaces and parking fees have not been confirmed.
The route from the parking lot at the valley entrance to Ibanmsanseong Fortress is described as an uphill course of about one hour. Other information explains that the route from Jeonnam National University Training Center to Ibanmsanseong Fortress also takes about one hour, and that the trekking route is not steep, allowing children and older adults to walk slowly with breaks.
The 8-kilometer round trip and 10.4-kilometer course are different
The round-trip course from Jeonnam National University Training Center passes the valley junction, the southern gate of Ibanmsanseong Fortress, the northern gate, and Gatbawi before returning. It is 8 kilometers in total and takes about 3 hours 20 minutes. Since it includes the southern gate, northern gate, and Gatbawi of Ibanmsanseong Fortress, the time required differs from an itinerary that only explores the valley entrance.
The Ibanmsanseong Fortress trekking course listed in Jangseong-gun tourism materials is 10.4 kilometers and takes 4 hours 10 minutes. Since the route can take about one hour from the entrance to the fortress, while a full hike requires either 3 hours 20 minutes or 4 hours 10 minutes, it is safer to decide on your destination before setting out.
Transportation figures to know when departing from Gwangju or Jangseong
If traveling by bus from Seoul, premium buses operate from Central City Terminal to Jangseong. According to the Jangseong-gun tourism map, the fare is 26,100 won and the journey takes 3 hours 15 minutes. The operator is listed as Kumho Express.
Transportation connecting Gwangju and Jangseong is listed on the 2025 Jangseong-gun tourism map as having a first bus at 06:15, a last bus at 22:30, 36 services per day, and 30-minute intervals. The phone number for Jangseong Station is 061-393-0588, and the phone number for Baegyangsa Station is 061-392-9044. However, the route number and stop for buses going directly to Namchang Valley have not been confirmed, so foreign visitors arriving for the first time should travel to Jangseong and then check local connecting transportation separately.
Admission appears to be free, but operating hours have not been published
Regarding admission to Namchang Valley, it is safest to say only that no separate fee has been identified on the official page. Meanwhile, operating hours and regular closing days have not been confirmed in the official tourism information. Rather than assuming there are fixed opening and closing times as at a museum, it is practical to plan to arrive during the daytime and finish the hike before dark.
Information from Naejangsan National Park states that access may be restricted when weather advisories for heavy rain or typhoons are in effect. Regardless of the fact that operating hours are unknown, restrictions may be imposed due to weather conditions, so travelers coming from far away should contact Namchang Management Office before departing. The phone number for Namchang Management Office is 061-393-7288.
Restrictions that are easy to overlook in the cedar forest and nature observation trail
The trekking section includes a cedar forest and is introduced as a place where visitors can walk while listening to the sound of valley water beneath dense greenery. Namchang Valley Nature Observation Trail is described as an outdoor experiential site operating year-round from January through December, with programs addressing environmental and ecological awareness through guided interpretation and hands-on activities.
Nature observation trail programs also include content about the daily lives of the ancestors of the Namchang area, such as traditional Korean paper, charcoal kiln sites, and soil experiences. However, whether photography is prohibited, whether English guidance or an audio guide is available, the location of on-site restrooms, and which areas of the valley permit water activities or are seasonally restricted have not been confirmed. Since special protection zones are off-limits, it is important not to leave the designated trail even when taking photographs of the valley.
A day combining Baegyangsa Temple and Jangseongho Tourist Site
The Jangseong-gun tourism map presents Jangseongho Tourist Site, Namchang Valley (Ibanmsanseong Fortress), and Baegyangsa Temple as one route. If visiting only Namchang Valley, the itinerary can vary greatly from a roughly one-hour round trip to the fortress to trekking courses of 8 kilometers and 3 hours 20 minutes or 10.4 kilometers and 4 hours 10 minutes. Therefore, when adding other attractions on the same day, it is more suitable to choose a short exploration of the valley.
Namchang Valley is introduced as a summer retreat long known to people in Gwangju and Jangseong, but based only on the confirmed information, it is not possible to definitively identify a specific water-play area or convenience facilities. It is better suited to travelers who want to walk through forest trails and up to the fortress, where no separate admission fee has been confirmed, and who can follow protected-area rules, rather than to travelers seeking a facility-managed place such as a swimming pool.
