The area is scientifically noted for having one of the highest concentrations of negative ions in Taiwan, often exceeding 100,000 ions per cubic centimeter.
The waterfall's distinct concave rock shelter, known as 'Tiandi Yan' or Heaven and Earth Eye, allows visitors to walk behind the falling water.
The temperature at the waterfall is consistently significantly lower than the surrounding low-altitude regions, often remaining below 20 degrees Celsius even in summer.
The water source for the falls originates from the high-altitude stream systems of the Alishan mountain range.
The rock structure is a type of sedimentary sandstone that has been carved out by the waterfall over centuries.
Songlong Rock Waterfall is located within the Shanlinxi Forest Recreation Area in the Xitou region of Taiwan. The waterfall cascades approximately 30 meters over a concave rock overhang, creating a natural amphitheater. A wooden boardwalk trail extends directly behind the waterfall, allowing visitors to view the cascade from beneath the rock shelter. The site is characterized by high concentrations of negative air ions and phytoncides due to the dense surrounding forest. The rock cliff features a unique concave geological formation caused by long-term water erosion. The waterfall is part of a larger trail network that connects to the surrounding cedar forests and alpine landscapes.
From the wooden bridge facing the waterfall, which captures both the scale of the cliff and the cascading water.
Wear footwear with good grip, as the wooden boardwalks and surrounding stone paths can be slippery from waterfall mist.
Bring a light waterproof jacket or rain shell, as the spray from the waterfall is constant and can soak clothing quickly.
Combine this visit with the nearby 'Earth Eye' trail to see the full extent of the geological formations.
Attempting the walk during heavy rain or typhoon season, as the trail may be closed due to falling rock risks or high water levels.
The area may close temporarily during severe weather events or typhoons; check local mountain weather advisories before traveling.
Stay strictly on the designated wooden boardwalks to protect the fragile rock wall ecosystem; do not attempt to climb the rock face.
