I did 25 days Saribung Peak expedition with Third Rock Adventures. It was an amazing experience, everything was perfect from my arrival in Kathmandu until last day. It was my first himalayan experience and my first high altitude mountain expedition. The company are the best travel company I have ever used-the communication was so fast and efficient. My sherpa guide Chhewang was incredible and very careful, he taught me everything I had to know for the summit day and it was a success! Naba organized perfectly, It was the best climbing experience around with beautiful mountains and great trip. It is true, Nepal - Once is not enough. I will be coming back for other trips in future with them again. Namaste.
