Don Khong (Khong Island), the largest island in the Mekong River’s Si Phan Don archipelago, offers an atmosphere even calmer than its famously tranquil neighbours, Don Khon and Don Det. Life here moves at a soothing, unhurried pace. Most activity revolves around Muang Khong, the island’s main town, while Muang Saen on the western shore is beloved for its spectacular sunset views across the river. A network of cycling and walking trails weaves through Don Khong’s landscapes, leading travellers past welcoming villages, serene temples, glowing rice paddies and sweeping river vistas—making it an idyllic escape for those seeking quiet beauty and authentic Lao island life.
