Just a great experience from the first moment we contacted Naba from Third Rock Adventures until long after we finished the trek. He was very prompt and concise in responding before we went to Nepal, and when we arrived in his office in Thamel to talk about the trek, he immediately introduced us to the guide (Babu, best guide we've ever had). Naba asked a lot of questions about us to make sure he could compose the perfect trek for us. There was a lot of flexibility, and we decided to add a trek to the holy Gosaikunda lakes while already on the Langtang trek. Everything was taken care of perfectly. Babu had our safety and experience in mind first, and had great advice and ensured we had no problems with altitude. He is very experienced - ask him about all his adventures in the Himalayas! During the trek, he taught us a lot about Nepal, the Tamang culture, and all other things we as Western visitors were curious about. We felt safe, unpressured, free and comfortable at all times. Naba and Babu have become good friends and we would recommend travelling with them to everyone. Thanks for everything!
