The Cheondong route is the most frequently utilized path for hikers aiming to reach Birobong Peak, the highest point of Sobaeksan at 1,439 meters.
Sobaeksan is home to the endangered Korean mountain goat, which is currently subject to a government-led population restoration program.
The trail features a transition zone where deciduous broad-leaved trees give way to subalpine coniferous forests as altitude increases.
Due to the high elevation and exposed peak, temperature drops of over 10 degrees Celsius compared to Danyang-eup town are common at the summit.
Cheondong District serves as the primary northern gateway to Sobaeksan National Park, providing one of the most accessible paths to Birobong Peak. The trailhead begins near the Cheondong Valley, characterized by a paved initial section that transitions into a well-maintained forest trail. Hikers frequently utilize this route for its relatively steady incline compared to other Sobaeksan approaches. The path follows a stream for the first several kilometers, offering a consistent water source and shaded environment. It is a favored route for spring azalea viewing and winter snow trekking. The district features a dedicated camping area and visitor amenities located at the base of the mountain ascent.
The wooden deck located at the junction just before the final climb to Birobong Peak, offering an unobstructed 360-degree view of the ridgeline.
Bring trekking poles, as the final ascent to the ridge is steep and consists of irregular stone stairs.
Check the national park website for 'mountain fire prevention' closure periods, which occur twice a year and restrict access to certain trails.
Ensure your footwear provides ankle support, as the trail surface transitions from asphalt to rocky, uneven terrain.
Do not attempt the hike in low-top sneakers, as the rocky, steep descent can cause significant joint strain and slipping.
Trails are periodically closed during high-risk wildfire seasons in spring and autumn; check the official KNPS website before departing.
Hikers must remain on marked trails to protect subalpine flora and must carry all trash out of the park as there are no bins on the mountain.
