The waterfall is fed by the Sakul Stream, which originates from the nearby mountains of the Central Mountain Range.
The rock strata surrounding the waterfall exhibit clear evidence of the tectonic activity common to the Hualien fault zone.
The site is often referred to locally as the 'hidden pool' due to its concealment by the dense forest canopy.
The water temperature remains consistently cool throughout the year, even during summer months.
Sakul Waterfall is a multi-tiered cascade located within the Sakul Trail area in Xiulin Township, Hualien County. The waterfall features a distinct rock pool at its base, carved into the local geological formations typical of the Taroko-adjacent region. The site is part of a protected ecological zone characterized by dense subtropical vegetation and limestone terrain. It serves as a natural swimming spot frequented by locals for its refreshing, clear mountain water. The area is integrated into a larger trail system that requires navigating uneven, natural terrain. Access to the waterfall pool involves a short hike through the forest canopy.
From the elevated rock ledge overlooking the main basin, which provides a full view of the tiered waterfall.
Wear water shoes with strong grip to navigate the slippery, algae-covered rocks near the pool.
Bring a waterproof bag for electronics, as the area near the waterfall base is subject to constant mist and humidity.
Visit during the midweek to avoid high foot traffic from local recreational groups.
Do not attempt to swim immediately after heavy rainfall, as the stream is prone to sudden, dangerous increases in water volume and debris flow.
The trail and waterfall area may be temporarily closed following typhoons or extreme seismic activity for safety inspections.
Practice 'Leave No Trace' principles, carry out all trash, and refrain from using soap or shampoo in the waterfall pool.
