When planning your Everest Base Camp trek, your journey will commence at Tribhuvan International Airport in Kathmandu, the capital city of Nepal. Kathmandu is the primary entry point for international travelers and serves as the starting point for most treks in Nepal, including the iconic Everest Base Camp trek. To reach the Everest region, you will take a domestic flight from Kathmandu to Lukla, a charming town nestled amidst the Himalayas.
