The area surrounding the bridge is part of a post-volcanic landscape featuring fumaroles that emit high-temperature sulfurous steam.
The soil in this region is highly acidic due to volcanic gas exposure, limiting plant life to acid-tolerant species like silvergrass and azaleas.
Xiaoyoukeng is situated on the northwestern slope of Qixing Mountain, the highest peak in Taipei City.
The sulfur deposits found near the site were historically mined during the Japanese colonial period.
Xiaoyoukeng Bridge serves as a vital viewing point within the volcanic landscape of Yangmingshan National Park in Taipei. The site features active post-volcanic geological activity, including steam vents and sulfur deposits visible from the bridge's perimeter. It is positioned along the Yangming Creek Walkway, offering a bridge-level perspective of the surrounding rugged terrain. The area is characterized by acidic soil conditions resulting from geothermal gases, which dictate the specific vegetation growth in the immediate vicinity. Visitors can observe the contrast between the lush mountain foliage and the barren, steaming slopes of the Xiaoyoukeng area. The bridge is integrated into the broader trail network that traverses the northern flank of the Qixing Mountain range.

Wear comfortable, non-slip footwear as the humidity can make surfaces near the volcanic vents slick.
Bring a light waterproof jacket, as the high-altitude volcanic area experiences frequent mist and unpredictable mountain weather.
Check local weather reports specifically for Yangmingshan, as it is often significantly cooler and windier than downtown Taipei.
Do not attempt to touch the steam vents or leave the designated walkways, as the ground can be extremely hot and brittle.
Stay on marked trails to avoid unstable ground and dangerous geothermal vents.
