The mountain is officially designated as a Nature Reserve for the preservation of its specific geological features and native flora.
The high concentration of iron oxide in the soil gives the terrain its signature vibrant reddish-orange hue.
The trail's ridge line provides a clear vantage point over the Daan River valley below.
Due to the instability of the conglomerate terrain, the trail route is periodically adjusted by local authorities to bypass landslide zones.
The mountain is part of the western foothills of the Central Mountain Range in Taiwan.
Huoyanshan (Flame Mountain) trailhead serves as the primary access point for a hiking trail characterized by unique badlands topography formed by intense tectonic uplift and erosion. The mountain’s distinct appearance features steep, craggy cliffs of red sandstone and conglomerate that resemble flickering flames under sunset light. The trail spans approximately 6.4 kilometers and involves a significant elevation gain leading to the 602-meter peak. Erosion is active in this region, resulting in deep gullies and constantly shifting landscape features. The geological composition consists primarily of Toukeshan formation conglomerate, which is prone to landslides. Vegetation in the area transitions from acacia forests at the base to sparse grasses near the exposed summits.
The 'Grand Canyon' viewpoint section provides the most iconic panoramic shots of the eroded red cliffs.
Bring a minimum of two liters of water, as there are no natural water sources or facilities on the trail.
Use trekking poles to navigate the steep, loose gravel sections on the descent.
Wear high-traction hiking boots to handle the slippery, sandy surface of the ridge path.
Do not attempt the hike during or immediately after heavy rainfall, as the conglomerate slopes become highly unstable.
The trail is subject to temporary closures during periods of severe weather, such as typhoons, for public safety.
Stay strictly on the marked path to prevent further erosion and avoid crossing safety barriers into restricted landslide zones.
