The Luxury Kongde trek with EBC and Kala Patthar Heli Tour is doable all year round. However, the best season for this trip is Spring (March to May) and Autumn (Mid-September and November-End). During both seasons, the temperature is stable and calm. There is a rare chance of flight delays and cancellations. Not only that, during this time, skies are clear, and the mountain views are at their best.
