The trail's name 'Longguomai' refers to the local water delivery system that historically irrigated the rice fields of Linnei.
The trail features a rare tunnel construction dating back to the Japanese colonial period, designed specifically for water diversion.
The path provides a direct view of the confluence area of the Zhuoshui River, Taiwan's longest river.
It is a key segment of the regional trail network designed to preserve traditional irrigation history while promoting ecotourism.
The trail elevation gains are moderate, making it accessible to hikers who are comfortable with uneven, unpaved surfaces.
Longguomai Forest Trail is a 3.1-kilometer linear path located in Linnei Township that follows the historical path of the old Japanese-era irrigation canals. The trail is distinctive for its combination of historical hydraulic engineering features, such as the Longguomai tunnel, and dense local forest ecology. It offers an elevated perspective of the Zhuoshui River valley and the surrounding agricultural plains of Yunlin. The route transitions through diverse vegetation including bamboo groves, fruit orchards, and native broad-leaf trees. Visitors pass through a man-made tunnel carved directly into the mountain rock, which served as a critical water transport channel. The terrain is primarily composed of stone and gravel paths with sections of stairs. It serves as a connector between the Longguo area and the local mountain ridges.

Carry extra drinking water as there are no refreshment stalls on the trail itself.
Bring insect repellent, as the humid, forested sections attract mosquitoes and small flies.
Ensure your mobile device has offline maps saved, as cellular service can be inconsistent in the deeper mountain sections.
Do not attempt the hike during or immediately after heavy rainfall due to the risk of falling rocks and mudslides.
Wear sturdy, closed-toe hiking shoes; stay on marked paths to protect local soil stability; do not feed wildlife.
