People with a determined mind and physical fitness, should trek at high altitude sometime in their life. Trekking is one grade difficult to walking in the hilly terrains and one grade easier than negotiating the mountain passes. Whatever it may be, trekking seem to be a simple adventure sport, but many a times it turns out to be hazardous and life threatening. From the time you finish your breakfast and leave the hamlet to start the trek, until the time you return back to the same spot or to any other rest house; you are always at a risk of injury, threat to your life, or at least in a situation of SOS. I have trekked at high altitudes in India and Nepal with my children, aged 4½, and 8 ½ year olds. They did not take a piggy back to the base camps, but trekked up to an ALT.19000.
