Sagarmatha National Park, home to Mount Everest, offers breathtaking mountain scenery and unique Sherpa culture. Accessibility can be challenging due to high altitude and rugged terrain; trekking is the primary way to explore. While solo treks are possible for experienced mountaineers, guided tours are highly recommended for safety and logistical support. The best time to visit is during the pre-monsoon (March-May) and post-monsoon (September-November) seasons for clear weather. Expect to pay park entrance fees and potentially trekking permit costs, along with accommodation and food expenses, which can add up significantly. A typical trek to Everest Base Camp lasts 12-14 days, but shorter treks are also available. Be prepared for altitude sickness and ensure you have appropriate gear and acclimatization plans.
