This is the description of a seven day trek that makes a circuit of the Helambu region. The easiest starting point for this trek is sundarijal because of its proximity to Kathmandu. You can make the trek in either direction.because it closes a loop from pati Bhanjyang,the first night stop of the trek.The preferred route is clockwise as i have described here; visit the high ridge to the west of Helambu Valley first,then go to Tarke Gyang and descend the Malemchi Khola before climbing back to pati Bhanjyang.There are all kinds of other possible variations, including a direct route to Tarke gyang from pati Bhyajyang,ending at panchkal on the Chinese road.
