You can get altitude sickness in Bhutan

Bhutan is a landlocked country tucked up against the Himalayan mountain range. As a result, much of the country is at a very high elevation. The northern half of the country, in particular, is very mountainous and high. This means that visitors to the country's north may occasionally experience symptoms of altitude sickness. This is especially true if you go trekking in the mountains of Bhutan.

Gangkhar Puensum is Bhutan's highest point, rising 7,570 meters (24,836 feet) above sea level. This mountain, which is located on the country's northern border with Tibet, is a contender for the highest unclimbed mountain in the world! When someone who does not live at a high altitude ascends above 3,000 to 4,000 meters, he or she is likely to experience mild altitude sickness symptoms. Nausea, headaches, dizziness, and insomnia are among the symptoms. Many of Bhutan's most popular tourist destinations are located in the country's mountainous northwest. As a result, it might be a good idea to visit your doctor before traveling to Bhutan to discuss altitude medications.
