Sanshuitan literally translates to 'Three-Water Pool,' denoting the junction where the Beishi and Wan-dan streams meet.
The Danlan Trail is part of a larger historical network spanning over 200 kilometers across Northern Taiwan.
The stone-arch bridge at the confluence is a key heritage landmark of the former postal route.
The area serves as a primary hub for hikers transitioning between the northern and southern segments of the Danlan Trail.
The water clarity is supported by the surrounding protected watershed area of the Shuangxi District.
The Danshui Ancient Trail: Wantan Section, specifically the Sanshuitan area, serves as the confluence point where the Beishi and Wan-dan streams merge. This location is a pivotal node in the historic Danlan Trail network, which once functioned as a vital commercial and postal route connecting Taipei and Yilan during the Qing Dynasty. The area features a distinct stone-arch bridge, known as the Shuangxi Small Bridge, that crosses the convergence point. The trail segment is characterized by lush subtropical forest cover, clear stream pools, and remnants of heritage stone pathways. It provides access to the larger Danlan Trail South Route system, linking Shuangxi to surrounding mountainous areas. The landscape is primarily composed of secondary forests and riparian ecosystems, facilitating local biodiversity. Visitors access this section via a dedicated trailhead leading into a valley marked by high humidity and significant river erosion patterns.
The mid-point of the small stone bridge looking toward the water confluence provides the iconic viewpoint for this location.
Wear high-traction hiking boots, as the stone pathways and stream-side rocks become extremely slippery when wet.
Bring a trekking pole to assist with stability on the uneven, moss-covered historical stone steps.
Carry sufficient insect repellent, as the humid, forested environment near the stream is prone to mosquitoes and midges.
Avoid visiting during or immediately after heavy rainfall, as the trail sections near the stream are prone to flash flooding and dangerous, slippery terrain.
Practice 'Leave No Trace' principles; do not disturb the local flora or throw waste into the stream, as this is a critical watershed area.
