The wetland acts as a massive natural sponge, filtering water from the surrounding hills before it flows into the nearby Dongyuan Lake.
The soil composition is primarily peat, formed by centuries of decomposing organic matter that has created a bouncy, floating ground layer.
The area is home to endemic plant species, including the rare purple-flowered 'Schoenoplectus mucronatus', which blooms seasonally.
It is a traditional Paiwan cultural site, and the management requires visitors to be accompanied by local tribal guides to ensure environmental preservation.
Dongyuan Water Grassland is a unique high-altitude wetland ecosystem located in the Mudan Township of Pingtung County. It is characterized by a thick, buoyant layer of aquatic vegetation and peat that rests upon a marsh, creating a 'water-walking' experience where the ground undulates beneath visitors' feet. This area is a protected indigenous territory managed by the local Paiwan community, serving as a vital habitat for diverse wetland plants. The landscape is surrounded by mountains and forests, maintaining a consistent water level throughout the year. Visitors walk directly onto the marshy vegetation surface, which is stabilized by complex root systems. The site remains a strictly preserved ecological zone under the stewardship of the Dongyuan village community.

Wear shorts or trousers that can get muddy, as the water level can reach above your ankles.
Bring a waterproof bag for electronic devices to protect them from potential splashes or humidity.
Prepare for sun exposure as there is very little natural shade across the open marshland.
Attempting to enter the wetland without a pre-booked local guide, as unauthorized entry is prohibited to protect the fragile soil structure.
Visits must be arranged in advance through the Mudan Township Dongyuan village community office; entry is often restricted during extreme weather conditions.
Visitors must be accompanied by a certified local Paiwan guide. Do not litter or pick any vegetation. Follow the guide's instructions on where to step to protect the ecosystem.
