Overview
Hidden deep within the wild, undulating highlands of the West Khasi Hills, Nongkhnum (also spelled Nongkhnum) is the second largest river island in India after Majuli and the largest in the state of Meghalaya. Covering an area of roughly 20 to 25 square kilometers at an elevation of 1,400 meters, Nongkhnum is formed by the dramatic bifurcation of the mighty Kynshi River into two distinct branches: the Namliang River flowing south and the Phanliang River flowing north, which reunite after circumscribing the island.
What makes trekking on Nongkhnum utterly magical and unexpected in a high plateau state like Meghalaya is its expansive white-sand river beach. As the Kynshi River broadens into a tranquil, crystal-clear lagoon at the island's entrance, it creates a sweeping coastline of fine golden-white river sand bordered by whispering groves of Khasi pine (Pinus kesiya) and wild bamboo that looks more like a tropical seaside cove than an inland mountain plateau.
The trekking trail explores the island's sandy perimeter, crossing rustic wooden suspension footbridges and winding through open grassy meadows where wild orchids bloom. The highlight of the trail is the thunderous Weinia Falls, where the river suddenly plummets over a colossal horseshoe-shaped rock ledge into a deep, mist-filled canyon. A short hike downstream reveals the Langshiang Falls—one of the highest waterfalls in India—cascading nearly 337 meters down sheer sandstone cliffs.
Nongkhnum offers an incomparable wilderness camping and trekking experience for travelers seeking total solitude, pristine freshwater beaches, and the raw, unhurried majesty of western Meghalaya.
