21D Tibet Everest Advance Base Camp Trek!
We call this the Highest Trek in the World, going to extreme altitude taking you as close to the summit of Everest as any nonclimber can go. You must be fit and tough, we camp in difficult conditions. Even being fit, there is still a chance of altitude sickness affecting you meaning that you may have to return to Everest Base camp and wait until the other trekkers return.
