Our plan to book Langtang valley trek for this season holiday finally materialized with Third Rock Rock Adventures. The entire team of this company was professional, friendly and helpful at every point of the trip. Our guide Bimal was absolutely excellent - incredibly knowledgeable and experienced so we knew we were in safe hands but on top of that he is a great guy and we really enjoyed his company for the trek. He went above and beyond for us and was always flexible to our pace, we did this trip just the way we want. Thank you all.
