The Kathmandu altitude has always been a major concern for all the visitors.

The Tribhuvan International Airport is the first destination, located at 1,338 meters above sea level. So we can say the Kathmandu altitude is around 1,400 meters above sea level.

Is the Kathmandu altitude considered high?

The Kathmandu altitude is not considered high, as it is located below 1,500 meters above sea level. The altitude below 1,500 meters is considered low, and the oxygen level is more than enough for the human body, so AMS is uncommon. When you reach a height above 1,500 to 2,500 meters above sea level, it is considered moderate, and you will notice a decrease in oxygen level, causing symptoms of AMS.

When you reach an altitude of above 2,500 to 5,000 meters above sea level, you will notice having more difficulty breathing because the atmospheric pressure decreases and the oxygen percentage drops significantly compared to sea level. Above 5,000 meters, the oxygen level drops more than half compared to sea level, causing different symptoms of AMS, and if not treated in time, it can be dangerous.

The Kathmandu altitude is high compared to other capital cities. But it falls under the low altitude with a low risk of suffering from symptoms of AMS. The physically fit and healthy adults, children, and kids can easily explore Kathmandu without any problem. But your body might need a few days to adjust to the new environment and weather.

Kathmandu Valley Geography

If you want to understand the Kathmandu altitude, you must know about its geographical structure. The land of the Kathmandu Valley is an oval shape covering 25 kilometers from east to west and 19 kilometers from north to south. And the Kathmandu altitude is about 1,400 to 1,600 meters above sea level.

The entire valley is surrounded by hills, forming a circular edge around the lower elevation. These hills rise to around 2,000 and 2,800 meters above sea level. Beyond these tall hills, you can explore the great Himalayan Range, which can be seen on a clear day. The winter morning in Kathmandu offers an opportunity to enjoy the view of majestic mountains like Ganesh Himal, Langtang Lirung, and Shisha Pangma.

A Valley Born from a Lake 

According to the ancient stories of Buddhist and Hindu legends, Kathmandu Valley was previously a very large freshwater lake that was formed by cutting a cliff with the sword of the god Manjushri. The modern geology supports the legend at this point because in the Pleistocene epoch, the valley was indeed covered with a huge amount of freshwater lake and the flat, fertile land for over thousands of years.

The Bagmati River that runs through the valley and by Pashupatinath is the river that cut the drainage point for the valley, and then the lake was drained to leave an uninhabitable basin. The history of the area explains how Kathmandu’s floor has such an extraordinary degree of flatness when compared with something that should have been formed by the rising of the Himalayas.

Kathmandu provides trekkers and mountaineers the opportunity to explore different trails and new adventures. Nagarkot is only 2,175 meters high and located on the east side of the valley, from where you can enjoy the most famous sunrise views of the Himalayas.
