The two most probable causes that you cannot continue via the high passes are either due to your physical condition or because of the heavy snowfall and ice-trail or landslide and adverse weather conditions. 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 by traversing back to Thame or to Namche Bazaar via Gokyo in case you have already crossed the Renjo La Pass. From here, it is possible to catch up the regular route to reach Tengboche and continue up to Everest Base Camp. In such cases, we request trekkers to be flexible enough to either completely give up the trek or then increase your trekking duration by a few days if necessary and if your health conditions permit.
