The two most probable causes that you cannot continue via Cho La Pass are either due to your physical condition or because of the heavy snowfall and ice-trail or landslide with continuous rock falling. Adventure in the high mountains comes with limited access while health and weather challenges are always to be considered. The time of the year you would want to do this trek also matters when considering the weather conditions. This is why Himalayan Glacier is always available with an alternate plan – the plan B, for safety reasons as well as equally enjoyable climbing and trekking adventures. We do not anticipate any adverse conditions but, in case weather gets bad and disrupts the trail, we offer you to continue the trip via other side of the valley – the regular route from Tengboche onwards. In such cases, we request trekkers to be flexible enough to either completely give up the EBC trek or then increase your hiking duration by a few days if necessary and if your health conditions permit.
