I was recommended by a friend to take service of Extollo Adventures and it was more than expected. Everything from trip planning, arrangements and operation was carried out very smoothly. All of us at the trip loved experience of mountain trekking, local life and beauty of natural environment in Himalayas o Nepal. The helicopter tour from Namche to Everest Base Camp, Kalapatthar, Gokyo Lakes and back to Lukla was outstanding.  Entire tour included memorable services in the luxury facilities . Highly recommended for everyone. The team exceeded our expectations.
