I just completed the Everest Base Camp trek with a team of my friends. Third Rock Adventures did their best job in organizing our trip efficiently and without any problem. They were AMAZING. Our guide was incredible and very knowledgeable. The porters were terrific. There was nothing to fault about this tour. I got sick when on the way back from Base Camp and the guide literally saved my life. Thank you is just enough for this company, so we decided to do every trip in the future with this company.
