Smack in the middle of Ngo Luong-Ngoc Son Jungle, Mu Waterfall, Hoa Binh is a multitiered azure cascade in the mountains. A short hike past fig-scented woodlands and seafood vendors takes you to the waterfall, which has several pristine pools for swimming and shady spots for relaxing. Families and groups staying overnight can rent Muong ethnic bungalows overlooking the waterfall.
