Mount Manaslu

Mount Manalu is one of Nepal’s highest peaks (8th), standing tall at 8,163 meters, giving a spiritual vibe to the region. As the word Manaslu comes from the Sanskrit word Manasa, it holds an intellectual reflection of the mountain's spiritual resonance.

But beyond its height and name lies a dual identity. A sacred trekking region surrounded by Tibetan culture and a dangerous yet alluring mountaineering challenge for elite climbers.

Whether you're a trekker seeking raw Himalayan beauty or a climber chasing the summit of one of the world’s deadliest 8000ers, Manaslu is a serious challenge that requires careful planning and respect for the mountain.
