This is your ultimate trekking challenge following in the footsteps of Hilary and Tensing Norgay, into the region where traditionally base camps have been erected for expeditions attempting to summit Everest. Supported by Across the Divide's famous standards for safety and group management the challenge will provide you with a once-in-a-lifetime opportunity to fundraise for your charity.
The trek follows the main route up to Base Camp and passes through some of the most spectacular scenery in the world. Everest becomes visible from just above Namche Bazaar and as we move through an ever changing environment and leave the tree line behind, the views of the mountains become more pronounced.
