Yes, it is possible to stop at Kalapathar for 10 minutes, depending upon the weather, time permitting as per the pilot’s decision. Can get very windy sometimes with a cold wind-chill factor especially from 11 a.m. onward.
The only spot that is close to Everest base camp, it offers a mind-blowing panorama of towering peaks with grand views of Mt. Everest at a close distance. The safest landing spot as well for spectacular views. Safety first so less time is better not to get any sickness.
