Kangchenjunga, the world's third-highest mountain, is a breathtaking tourist destination primarily known for trekking and mountaineering. Accessibility can be challenging due to the remote location and high altitude; permits are required, and engaging a local guide is highly recommended, especially for treks. Solo trekking is generally discouraged due to safety concerns. The trekking season typically runs from March to May and September to November, avoiding the monsoon and winter months. Treks can range from moderate to strenuous, with costs varying significantly based on the trek's duration, permits, and porter services, ranging from $500 to several thousand dollars. Typical visits last from 10 to 20 days, depending on the chosen trekking route. Be aware of altitude sickness and acclimatize properly. Pre-booking accommodations and permits is crucial, particularly during peak season.
