Its the world's deepest valley located in Nepal.
Utterly marvelous, still very untouched and an irregular trekking area of Makalu region is very close to the Everest region. Because of Arun River, it is known as Arun Valley too. The Arun Valley is an unimaginable area and it is famous for both the culture and nature.This area is a naturalist's paradise and it is teeming with many precious plants, animals and Mt.
