The Manaslu & Tsum Valley Trek is a breathtaking expedition that merges two of Nepal’s most culturally rich and geographically diverse trekking routes. The journey follows the Budhi Gandaki River through deep gorges and rhododendron forests to the mystical Tsum Valley, a sacred Himalayan pilgrimage valley located in northern Gorkha. Opened only in 2008, this secluded valley is home to Tibetan Buddhist communities known as the Tsumbas, who still follow a traditional way of life, untouched by modernity.
Continuing from Tsum, the route joins the Manaslu Circuit Trail, encircling the eighth-highest mountain in the world, Mt. Manaslu (8,163m / 26,781ft). This part of the journey offers epic Himalayan scenery, Tibetan monasteries, and challenging terrain, culminating in the crossing of the Larkya La Pass (5,160m / 16,930ft), one of the most dramatic high-altitude passes in the Himalayas. From remote stone villages and yak pastures to glacial moraines and alpine ridges, this trek is a perfect blend of spiritual isolation, raw Himalayan beauty, and cultural depth.
The Manaslu & Tsum Valley Trek is ideal for those seeking a less commercial, more immersive alternative to the Annapurna or Everest regions, with the reward of authentic Tibetan culture and majestic high-altitude landscapes.
