Heukseongsan rises behind the Independence Hall of Korea in Cheonan. Combine the museum with its autumn maple path for an easier walk, or continue to the mountain viewpoint and Heukseongsanseong Fortress for a real ascent. The maple path alone is not the summit trail.
Independence Hall maple path, hillside viewpoints and Heukseongsanseong Fortress
Begin at the Independence Hall entrance and follow the maple path to a signed B or C trail junction; the museum says route maps are posted along the path. Check opening and trail notices for your travel date, and return by a confirmed route.

Search for 흑성산 Cheonan, Chungcheong and select a marked entrance before departing. The mountain pin does not identify a trailhead.
Good times to consider
Spring · Autumn. Flowering, foliage, snow and trail conditions vary by date and year.
Before you go
Check local trail notices, forecast, daylight and the return journey. Route length and transport depend on the entrance you select.
