The strenuous grade encompasses both moderate and difficult aspects. Even within this grade, treks typically reach altitudes ranging from 5000 to 5500 meters. On a daily basis, you can expect to walk for approximately 6-7 hours. Undertaking strenuous treks necessitates being in good physical condition and acclimatizing properly. In case any issues arise, it is recommended to descend and consume hot beverages or soup. Individuals with high blood pressure, asthma, heart disease, or other complex medical conditions may experience rapid effects.
