Great Trek with Bimal! I am more than satisfied with the service level of this company. Atrek with another company was somehow bad if comparing their with Third Rock's service. You should not always go with popularity of a company. Make sure to check their review and also get to know with the company. I was in contact with Naba, the main brain behind this company and loved how he approached me and offered me the info. They are just great, and you are suggested to book with them. Make sure to talk with Naba for any customization and interest. He personally customized this trek and I added Mardi Trek.
