Third Rock Adventures is a trustworthy company, Naba the founder of this company is the man you should be talking with for your next adventure to Nepal. I throughly enjoyed my trek to Annapurna Base Camp. Before I traveled to Nepal all of my questions and concerns were answered by Naba. He called me to ensure everything before I booked, He even gave me time to rethink and book only when I am ok with the itinerary. He was open to customizing the itinerary but I liked the standard itinerary. My guide Bimal expertly handled all of the additional logistical changes that needed to be made. It was truly amazing experience.
