Par Le Stream (also known as Parle Stream) is nestled in Hong Ha Commune, A Luoi District, Thua Thien Hue Province – a mysterious mountainous highland region. Located about 50km southwest of Hue city center, the stream is in the Vietnam-Laos border area, surrounded by majestic limestone mountains and almost intact primary forests. Not just an ordinary stream, Par Le is also the "green lung" of A Luoi, featuring an upstream cave system and two large swimming pools: Cat Toom Basin (5m high, over 100m²) and Am Bat Basin – an ideal spot to plunge from high rocks into the crystal-clear water.

The history of Par Le Stream is closely associated with the Pa Co and Co Tu ethnic minority communities living here. The name "Par Le" originates from the local language, meaning "fresh headwater stream", reflecting the purity of the water from forest aquifers. Previously, the stream was mainly a place for locals to bathe and fish, but since the 2010s, it has gradually become an eco-tourism destination thanks to its pristine beauty and fresh air. To date, Par Le Stream has attracted thousands of visitors every year, especially young people who love exploring and taking check-in photos.
