- Alliance Adventure

The Tilicho Lake & Thorong La Pass Trek is one of Nepal's most spectacular high-altitude adventures, combining the breathtaking beauty of Tilicho Lake (4,919 m)—one of the world's highest alpine lakes—with the thrilling crossing of Thorong La Pass (5,416 m), the highest point of the classic Annapurna Circuit. This unforgettable journey leads trekkers through lush river valleys, pine and rhododendron forests, dramatic cliffs, traditional Himalayan villages, ancient Buddhist monasteries, and the arid landscapes of the Trans-Himalayan region before descending to the sacred pilgrimage town of Muktinath.

Perfect for experienced trekkers seeking both adventure and natural beauty, this trek offers a unique blend of Himalayan culture, diverse ecosystems, and some of the finest mountain scenery on Earth. Tilicho Lake lies in a glacial amphitheater west of Manang, while Thorong La Pass is the iconic crossing that links the Manang and Mustang regions.

Why Choose the Tilicho Lake & Thorong La Pass Trek?

This trek combines two of the Annapurna region's greatest highlights into one remarkable journey. Rather than following only the Annapurna Circuit, trekkers take a scenic side trip to the turquoise waters of Tilicho Lake before returning to rejoin the main trail and cross Thorong La Pass.
