The Manaslu and Annapurna Cicuit and tilicho lake trek is one of the best trekking in Nepal. Manaslu Circuit Trek is one of the best remote trekking areas in Nepal, predominated by Baudha Himal, Gorkha Himal, and Himal Chuli, bordered by two major river systems: the Budhi Gandaki to the east and the Marshandi Khola to the west. The Annapurna and Manaslu ranges, including the two major alpine high passes: Larkya La Pasa (5,160 m) and Thorong La Pass (5,416 m), are the significant highlights of the Manaslu and Annapurna circuit trek that begins in Gorkha, which follows the Marshyangdi River for the first few days and moves along the rugged gorge of the Budhi Gandaki River via indigenous Gurung villages with a vast number of Buddhist monasteries. A few sections of the trek also feature numerous high waterfalls cascading on the main river, while the valleys shelter several ancient temples, some of which represent the pre-Buddhist Bon religion, rising slowly with the minimum chance of altitude sickness. As the river changes course to the west, so do the landscapes, with steep, rocky gorges and pines covering the forest.
