Visit the charming Hieu Village (Bản Hiêu), famous for its stunning multi-tiered Hieu Waterfall (Thác Hiêu). Follow the stream as it cascades down the hillside over smooth rocks, forming numerous natural pools perfect for a refreshing swim on a warm day.

The village itself, primarily Thai ethnic minority, is nestled beautifully along the stream amidst rice terraces and lush greenery. Trekking to Hieu Village and enjoying its beautiful waterfall is a popular and rewarding Pu Luong activity.
