Zhuzi Mountain, Summit volcano in Sanzhi District, New Taipei City, Taiwan
Zhuzi Mountain is a volcanic summit in the Sanzhi District of New Taipei, part of the Tatun Volcano Group, with two distinct peaks rising above the surrounding hills. The slopes are steep and covered in dense forest, giving the mountain a solid, compact shape when seen from the valleys below.
The mountain took shape hundreds of thousands of years ago when volcanic activity built up the chain of peaks now known as the Tatun Volcano Group. That system is now considered dormant, though some parts of the broader area still show signs of geothermal activity.
The name Zhuzi means "bamboo" in Chinese, pointing to the groves that once dominated the slopes and gave the mountain its identity. Walkers on the lower trails can still pass through patches of bamboo that have survived between the denser forest.
The main trail begins in Sanzhi District and climbs through forested sections that get steeper as you go higher. Good footwear is important, and it is worth planning the hike without expecting to reach the very top, since the summit area is restricted.
A military installation at the top means that the highest point is permanently off-limits to the public, which is unusual for a hiking destination in this part of Taiwan. The trail effectively ends before the true summit, so the climb feels different from a standard peak walk.
