Elevation gain during the Everest Base Camp Trek
The Everest Base Camp trek is a rollercoaster traversing various elevations. Elevation gain (altitude gain) refers to the vertical distance you ascend during the trek. In other words, it's the difference in altitude from where you start to where you end up at the top. Understanding elevation gain is essential for a successful and satisfactory experience.
In this section, we delve into the elevation profile of the Everest Base Camp trek and critical landmarks. This information helps you understand what to expect daily during your trek and prepare accordingly.
Kathmandu to Lukla
Kathmandu is the starting point of the journey to Everest Base Camp. You fly to Lukla, the gateway to Everest, from Kathmandu and enjoy the scenic beauty. Due to the geographical obstacles and high altitude, Lukla Airport is considered one of the most adventurous airports in the world.

If you're looking for an extra adventure on your Everest Base Camp trek, the hike from Gorakshep to Kalapathhar is perfect. The challenging hike takes you to one of Nepal's most famous vantage points, which stands at a higher elevation than Everest Base Camp. Starting from Gorakshep, you'll hike on a rocky trail and achieve an elevation gain of 415 meters to reach Kalapathhar at 5,555 meters (18,225 feet). From here, you get magnificent views of the surrounding mountain peaks. After enjoying the view, you’ll head back down to Pheriche. This means losing significant altitude on your hike back.
Effects of Altitude on the Body
Air pressure and oxygen levels decrease when you make your way to the high-altitude area of the Khumbu region. The elevation gains can cause oxygen levels to decrease, which leads to hypoxia. The atmospheric changes can also cause altitude sickness, also known as acute mountain sickness. Altitude sickness features a range of symptoms, including difficulty breathing, headache, fatigue, nausea, dizziness, loss of appetite, and an increased heart rate. The elevation gain can also cause altitude-related illnesses, such as High Altitude Pulmonary Edema (HAPE) and High Altitude Cerebral Edema (HACE). These conditions start with a mild effect, but with elevation gain, it becomes worse and even life-threatening if proper preventive measures are not taken.
Acclimatization Strategies
Acclimatization is the process that helps your body adjust to the low oxygen levels at higher altitudes. All trekkers on the Everest Base Camp (EBC) trek need to rest and allow their bodies to acclimatize. Here are some simple tips to help your body acclimatize:
- Hike gradually to allow your body time to adjust to the changing elevation. Your EBC trek plan will have 2-3 days for rest and acclimatization.
- Go on short hikes during the rest days to allow your body to prepare itself for the steep ascend in the coming days.
- Drink plenty of water to stay hydrated. Eat a balanced diet with high-protein snacks and avoid caffeine and alcohol.
- Walk at a steady pace, and don't push yourself too hard. If necessary, take extra days to rest.
- Being fit and having good cardiovascular health helps immensely, as you won't burn yourself out on the trail.
- If you don't feel well, rest at the tea house. Only continue the trek when you feel healthy and in good condition.
- Following these simple steps, you can have a safe and enjoyable trek to Everest Base Camp.
Preparation for Everest Base Camp Elevation Gain
- Start physical training three months before the trek. Follow an exercise program focusing on cardiovascular health, endurance, and stamina. Indulge yourself in activities like swimming, cycling, and running.
- Go on shorter hikes prior to the EBC trek to train yourself to adjust to the high-altitude regions. This will allow your body to experience similar challenges you might face ahead.
- Study and keep yourself informed about the symptoms of altitude sickness. Learn useful tips to prevent it and its early symptoms.
- In your packing list for the EBC Trek, include suitable gear and accessories, such as study boots, trekking poles, and knee support, to avoid any further challenges with the elevation.
