G-Adventures is the only tour group that we know of that can bring you to Antarctica. Tours are developed with you in mind at every point of the trip. Some of these are longer adventure treks that will take you on an experience that will last a lifetime - like making your way to Everest Base Camp, the Great Wall of China, or Machu Picchu! Even though the adventure can be difficult, G-Adventures really tries to make you feel comfortable! Best in Class!
