Yes — the Everest Base Camp Trek is safe for physically prepared trekkers who follow proper acclimatisation protocols and trek with an experienced guide. The main risk is altitude sickness, which is actively managed throughout the trek.
Himalayan Glacier guides monitor blood-oxygen levels twice daily with pulse oximeters, carry emergency oxygen and first-aid kits on every departure, and follow strict protocols for altitude sickness response. Helicopter evacuation is available from any point on the trail within hours. All trekkers are required to carry insurance with helicopter coverage.
