In order to hike the Sham Valley trek, you need to have a moderate level of fitness since you’ll be hiking anywhere between 3-5 hours covering 5-9 km (3.1-5.6 miles). Even though this trek is also called “Baby Trek” and is considered to be among the easier treks in this region, you’ll still need to be able to acclimatize to the altitudes in these mountainous areas. Keep in mind that you’ll also be packing a daypack filled with water and other things you’ll need throughout the day.
