Yes, the Cho La Pass is quite dangerous and the intensity of the challenges depends on the time of the year you are doing this trek. Trekkers must be very careful to do this trek during winter, post-winter and rainy seasons. To be precise, the rocky path from Gokyo to Dzongla is the most challenging segment on the entire trek. During the pre, mid or post winter months of January, February and early March, the trail is filled with snow and ice making it very difficult to navigate the track at times. We move ahead with plan A and plan B after gathering information about whether any other team ahead of us has crossed the challenging section or not. Plan A is making sure to cross the pass and plan B is just giving up and returning for safety measures. There is nothing to worry about as we have expert leaders with experience and proficient knowledge to make sure about your safety measures at difficult times.
