The park name 'Naejang' translates to 'many secrets' in reference to the complex, mountain-enclosed valleys.
Naejangsan is home to the Geumseon Falls and the rare Dangun-gaengnamu tree, a species of maple endemic to the region.
The park contains a dedicated nature trail specifically designed for wheelchair and stroller accessibility starting near the visitor center.
The surrounding mountains, including Sinseonbong Peak, reach elevations of over 760 meters.
The Naejangsan National Park Naejang Visitor Center serves as the primary informational hub for exploring one of South Korea's most significant autumn foliage destinations. Located within the Jeongeup sector of the park, it provides maps, trail condition updates, and emergency assistance for hikers. The center is situated near the entrance of the main Naejangsan valley, which is home to diverse flora including over 700 types of wild plants. It acts as the staging ground for visitors heading toward Naejangsa Temple and the cable car station. The facility provides educational exhibits detailing the ecological diversity and conservation status of the park's mountainous terrain.
The map plaza directly in front of the center, which offers a clear view of the mountain peaks framing the valley entrance.
Check the real-time foliage forecast boards at the center during late October to time your visit with peak autumn colors.
Use the center's staff to confirm current trail closures, as routes near the higher peaks are frequently restricted during fire prevention periods.
Stock up on water and snacks here, as amenities are limited once you begin the deep-valley ascent.
Do not attempt to hike the higher peak trails without proper footwear, as the paths become rocky and steep beyond the temple area.
Trails are subject to seasonal closures during high forest fire risk periods in spring and autumn; check with the center for specific access limitations.
Hikers are strictly prohibited from straying off marked trails or collecting plant life; noise levels should be kept low to respect the proximity of the temple.
