There are some absolutely magnificent treks in the far eastern mountains of Nepal! The highest passes and biggest mountains are definitely wild, inaccessible, and some of the most beautiful trails in the entire Himalaya! Every year, many people visit the Everest area, while very few go to these two trekking regions combined!
For those who want an authentic trail experience that escapes the hordes of foreigners on the major trekking routes of Everest, Annapurna and Langtang, both the Kanchenjunga and Makalu trekking areas are fine.
