Everest and Island Peak Climbing During Monsoon (June, July and August)

Note: If you want to avoid paying extra, you should book your services with Nepali agencies rather than going through a third-party. Only registered Nepali companies are allowed to manage operations in the Nepali Himalayas.
Physical Preparation
Physical preparation is a must when it comes to high-altitude adventures like mountain expeditions. You will have to traverse across rugged and challenging trails of the Himalayan region before making your ascend on the alpine slopes, traversing across the rock, ice, and snow segments to the summit. Thus, for the physically demanding part of the journey, you will need to make enough preparations. Unlike the trekking adventures, you will have to be in your best shape for the mountain expeditions, especially if you are ascending a peak that rises above 8,000 meters.
The majority focus of your physical preparation should be on your endurance and stamina level.

Understanding the Risk of Altitude Sickness and Preventions
While doing a high altitude adventure, especially in the alpine zones where acclimatizing can be difficult due to cold climate conditions. Thus, you will need to understand the risks of various forms of altitude sickness that come along with your high-altitude journey and how to mitigate them. Enough acclimatizing period is a very crucial factor when it comes to high-altitude Himalayan expeditions. You need to give your body enough time to acclimatize to the alpine altitudes before pushing for further to even higher altitudes.
There are basically three types of altitude sickness: the milder form of altitude sickness is known as Acute Mountain Sickness (AMS), and a slightly milder form is called High Altitude Cerebral Edema (HACE), which causes the brain to swell. The final and last stage of mountain sickness is called High Altitude Pulmonary Edema (HAPE), where fluids leak from the blood vessels and accumulate in the lungs. During your expedition, you need to understand the risks and symptoms of these conditions and follow appropriate measures to avoid any kind of inconvenience.
Hydration and Nutrition Monitoring
During your iconic Himalayan expeditions, you will spend a significant amount of time on the mountain, eating and resting at the teahouses on the trails and camps on the mountains. Thus, it is important to monitor your hydration and nutrition during your iconic adventure. If you don’t eat a balanced diet to fuel yourself for the expeditions, it can weaken your body and expose you to the risks of not just altitude sickness but other general illnesses as well.
Similarly, during the long hours of trekking and scaling, you will lose a significant amount of boy water level. To keep the water level of your body at an optimum level, you will need to drink at least 3 to 4 liters of fluid per day. This will help you to move around more comfortably and mitigate the risks of altitude sickness. You should also pack nutritious snacks, energy bars, and drinks for a quick energy boost during the journey.
