Dhaulagiri, the world's seventh-highest mountain, is a major trekking destination in Nepal, offering challenging high-altitude routes with stunning Himalayan views. Treks typically last 14-20 days and are strenuous, requiring a good level of fitness and acclimatization. Accessibility is limited, with flights to Jomsom followed by trekking. Solo trekking is possible but not recommended due to the remote and challenging terrain; guided treks are highly advised for safety and logistics. Optimal trekking seasons are spring (April-May) and autumn (September-November) to avoid monsoon rains and winter snow. Costs can range from $1500 to $4000+ per person, depending on the level of service and trek duration. Note that altitude sickness is a significant risk, and comprehensive travel insurance is essential.
