Today is your adventure day in whole trekking in Annapurna which is unforgettable because you will cross the world's highest Pass (Thorong-La-Pass 5416m). You will walk very early morning having an 8-9 hours walk to Muktinath. There is no technical problem but needs a physical walk to succeed. You must walk slowly, and safely with your trekking crew though our Guide and Porters will be with you. The cross is not hard but it is long and gradual. During your Climb, you will have a fantastic view of the Annapurna Range, Chulu west and east, and the incredible Kali Gandaki Valley. 
From Thorong Top, the east part of water and ice moves to Marsyandi River and the west part moves to Kali Gandaki River. After a 3-4 hours Hike from Phedi, you will be at the top, take photographs, and steep down to Kali-Gandaki Valley with an amazing view of Dhaulagiri (8,167m) and Tukuche Peak (6920m). After you step down Mustang district begins and finally, you will reach in Hindu/Buddhist Pilgrimage of Muktinath. Now, you are very tired and rested overnight at the Tea House of Muktinath Village. In the evening, hike fifteen minutes to the famous Hindu Temple Muktinath where many Hindu people from Nepal and India come to worship and Pray to God Vishnu.
