We did Manaslu trek with Third Rock Adventure company and we are more than happy. They gave us the best guide for this trek, which we didn't much expect. The guide was friendly and knowledgeable. He managed the room before we reach the place, how convenient is it :) Naba would contact us time and again to know the update on the trek. The trek is quite remote trek, so we added an extra two add for contingency, which Naba customized for us. The best part of this trek was the scenary and local people. We loved to get in touch with them and learn about their local lifestyle.
