Dashu shan, Mountain summit in Shushan District, Hefei, China

Dashu Shan is a dormant volcano and the highest point in Hefei's urban area, rising 284 meters. Its oval form is higher in the southeast and lower in the northwest. Two ancient craters lie at the summit, and olive basalt lava falls, volcanic necks and conduits are visible on the slopes. The mountain is now a national forest park covering 13,000 mu.

Dashu Shan is a dormant volcano formed in the Cretaceous period about 140 million years ago, with two ancient craters at its summit. In 1998 it was combined with Hefei's Ring Park into a provincial scenic area, and in 2009 Anhui's forestry department approved it as a provincial forest park. It became a national forest park in January 2013.

The mountain serves as a gathering place where locals experience seasonal changes through blooming cherry trees, roses, and changing maple foliage. The walking paths naturally lead to resting spots where visitors linger and observe the surrounding landscape.

The mountain offers free entry with multiple hiking trails of varying difficulty and informational signs for navigation. Small shops and refreshment stands operate near the base for visitors who need supplies during their visit.

The mountain's slopes are notably gentle, with maximum grades around 30 degrees, making the climb accessible to visitors of varying fitness levels. Despite these moderate grades, the terrain supports over 20 species of evergreen and deciduous trees in dense growth.
