The high demand for helicopter slots and temple visits during September and October can lead to crowded conditions, particularly at Kedarnath and Badrinath. Pilgrims may face longer waiting times for darshan as the temple closing dates approach. Additionally, the cold weather, especially in Kedarnath, poses risks such as altitude sickness and discomfort for those unprepared. Early snowfall in October could also impact travel plans. Proper planning, including warm clothing and early bookings, is essential to mitigate these risks.
