20 Days of Trekking over high passes to Makalu Base Camp
Maximum Elevation 5000 metres (16,405 feet)

The trek to Makalu base camp visits one of the most remote and unfrequented areas of Nepal. The Barun Valley is part of a huge international protected area under an agreement between Nepal and China. The trek crosses several high passes as it climbs into the remote Barun Valley at the foot of Makalu, the world's fifth highest mountain.

This area was once threatened by a dam project on the upper reaches of the Arun River. The World Bank cancelled its support of this project in August, 1995, so this region will retain its unique character that includes interesting villages and wildlife.
