It is not so difficult, as one imagines as any other normal moderate-grade walks around the Himalayas. The only tough is gaining altitude from Pisang village onwards from above 3,000 m onwards. But taking time and enjoying the views and having short refreshing stops makes the trek much easier. The only hard day of walking is going over Thorang-La Pass. By then all trekkers will be well acclimatized with the altitude to encounter the difficult part of the adventure. Slow and steady with few stops in between the walks makes the trek more enjoyable.
