Everest Base Camp (EBC) is a world-renowned trekking destination accessible via a challenging multi-day trek (typically 12-14 days round-trip from Lukla), demanding good physical fitness and proper acclimatization to prevent altitude sickness. While theoretically possible to trek solo, it is highly recommended and often legally required to hire a licensed guide and/or porter for safety, logistical support, and local insights, making it primarily a guided experience. The optimal trekking seasons are pre-monsoon (March-May) and post-monsoon (September-November) for stable weather and clear mountain views, as winter (Dec-Feb) brings extreme cold and snow, and monsoon (June-Aug) presents rain and poor visibility. The approximate cost for an organized EBC trek, excluding international flights to Nepal, can range from $2,000 to $5,000+ USD per person, depending on service level, inclusions (flights to Lukla, permits, guide/porter, food, accommodation), and group size. Visitors should budget for a total duration of 2-3 weeks including travel to and from Nepal, and critically, ensure they have comprehensive travel insurance covering high-altitude trekking and emergency evacuation.
