As you are traveling over high terrain, you are likely to experience symptoms and discomfort of altitude sickness (headache, loss of appetite, nausea, exhaustion, sleeplessness, breathlessness etc.) until your body adjusts to the elevation. This can take a couple of days or more depending on an individual. For this reason alone, we have made it mandatory to stay 2 nights at Nyelam (12000ft) and a night in Simikot those who take journey of Helicopter before moving on to the higher altitudes. Drink plenty of water, be calm, and do not exercise. Do not drink alcohol or smoke prior to and during the tour. We also recommend you carry a strip of diamox tablets. Do consult your physician on the dosage. We provide Gamow bag (a special equipment to prevent sickness from high altitude) on this tour.
