This is a fairly popular trek because it is close to Kathmandu. It can be done in a week, and since it is below 3500m it can be done in the winter. The highest altitude is at 3490m. The trek makes a circle through the Sherpa Helambu that is northeast of Kathmandu.
 
Hidden among the oak rhododendron and fir forests, and these steep river valleys, are a number of sacred cave dwellings and meditation sites of historic lamas. The mountain scenery provides a stunning backdrop for a transcendental experience. Moderate elevations and easy access from Kathmandu make this an ideal wintertime.
