Muang Ngoi, particularly Nong Khiaw and Muang Ngoi Neua, offers extraordinary mountainous scenery with towering karst peaks rising from the Ou River. It serves as an excellent gateway to northern Laos or a convenient stop between Luang Prabang and Sam Neua or Phonsovan. Nong Khiaw provides good food, comfortable accommodation, and peaceful mountain hikes to caves and viewpoints. Tham Pha Thok Caves reveal local survival during the Indochina Wars, while Pha Daeng Peak and Sleeping Woman Viewpoint offer stunning vistas accessible by hiking. Muang Ngoi Neua, reached by a short boat ride from Nong Khiaw, offers a relaxed atmosphere with activities like fishing, mountain biking, kayaking, and tubing. Watching the sunset from the riverbank is a highlight.
