Commercial trekking on the Great Himalaya Trail (GHT) has begun. Two private companies- Nepalese and Australian- are jointly marketing this product. Nepal government had introduced GHT as a new product to during the inauguration of Nepal Tourism Year 2011 on Jan. 14. GHT is 4,500 km long and passes through Pakistan, the Tibet Autonomous Region of China, India, Nepal, Bhutan and Myanmar. The Nepali section of the GHT extends  from Darchula and Humla in the west to Kanchenjunga in the east, and takes some 157 days to trek.The trek in Nepal is divided into seven sections of 18-34 days each. As most people won’t have sufficient time to complete this adventure at one go, the company has devised seven treks that can be linked to make up the full traverse. The trip will be offered each year so that adventurers may choose to undertake the entire GHT over a number of years.
