The area is recognized as one of the most significant habitats for the Formosan birdwing butterfly in Northern Taiwan.
Negative air ion levels in this region are significantly higher than urban environments due to the presence of multiple waterfalls and dense forest cover.
The forest composition includes ancient hardwoods like Machilus and Castanopsis, providing a canopy that stays dense throughout the year.
The name 'Manyueyuan' (Full Moon) originates from the shape of a rock formation found in the nearby riverbed.
The trails were specifically designed to allow self-guided study of forest ecology using on-site informational signage.
The Manyueyuan National Forest Recreation Area Self-Guided Trail is a specialized path within a temperate broadleaf forest renowned for its high concentrations of negative air ions. The trail features a series of elevation changes designed to showcase distinct vertical forest strata. It provides direct access to the confluence of the Nanshi and Mugua streams, which nourish the surrounding lush vegetation. The path is structurally integrated into the broader park system, which is categorized as a low-to-medium altitude mountain environment. Visitors navigate through diverse botanical zones including sub-tropical and warm-temperate plant species. The trail serves as a primary educational loop for identifying regional endemic flora and fauna. It functions as a conservation zone for local insect populations, including the diverse butterfly species native to Northern Taiwan. The terrain involves natural stone steps and wooden decking to mitigate soil erosion.
