Slowly decend to Phakding 8,700 ft. about 2 hr walk from Lukla, you will probably overnight here.
The next morning after about 2-3 hours you will pass through Jorsale 9,100 ft. Here is where you will pay a fee and enter the Sagarmatha (Everest) National Parkand. You will then continue for another 2-3 hours up hill to the main Village of Namche Bazaar 11,300 ft. This is quite an elevation gain especially for those who have flown in. You should rest here one to two days, doing small side trips ect. to acclimitize.
