The mountain was historically formed by the uplift of coral reefs, resulting in fossils embedded within the limestone cliffs.
Yi-Xian-Tian, or 'a thread of sky,' is a natural narrow crevice that serves as a key geological landmark within the park's trail network.
The park contains several limestone caves that were historically utilized for meditation by local monks.
The limestone composition of the mountain leads to a unique karst landscape that supports plant species distinct from the nearby plains.
Dagangshan Natural Park is situated on a limestone mountain range in Alian District, renowned for its complex network of karst caves and rugged rock formations. The park is home to the notable Chaoyuan Temple, one of the oldest Buddhist sites in the region, which overlooks the vast Chianan Plain. Geologically, the area is characterized by coral limestone uplifted from the ocean floor, creating a distinct terrain compared to the surrounding alluvial lowlands. The trail system provides access to various rock shelters and natural caverns, including the well-known Yi-Xian-Tian, a narrow fissure between two cliff faces. Vegetation consists primarily of secondary forest and shrubland adapted to the alkaline, well-draining soil of the limestone base. The park serves as a site for both recreational hiking and religious pilgrimage due to the density of temples built along the mountain slopes.

Wear sturdy footwear with good grip, as limestone paths can be slippery and uneven.
Carry plenty of water and sun protection, as the trail areas offer limited shade and the limestone reflects heat.
Respect temple boundaries by observing quiet behavior, as these remain active religious sites.
Do not attempt to scramble off-trail on the limestone cliffs, as the rock is brittle and prone to fragmentation.
Maintain a respectful silence when passing through temple grounds and ensure shoulders and knees are covered if entering indoor shrines.
