The Around Annapurna Trekking/Annapurna Circuit is one of the classic treks in the world and on the must do’ list of any serious trekker or adventurer. The circuit takes one around the Annapurna Himal, following the courses of 2 mighty rivers: the Marsyangdi in the east and the Kaligandaki in the west, and takes one over the 5400m-high Thorung La Pass in between the upper reaches of the rivers. The Kaligandaki is the world’s deepest gorge, flanked by the giant Dhaulagiri and Annapurna Himal. The flora, geography and culture also change dramatically around the circuit.

In recent, Around Annapurna/ Thorung la pass trekking has become a very popular and busy place for trekking, after opening in 1997. A few lucky scientist expedition groups had trekked into this region in the past 1950’s. Any parties that are planning to do this trek must have a prim consideration with regard to the porter’s clothing and equipment at the moment of crossing Thorung La Pass (5,416). Sometimes it may be risky due to the bad weather, such as snowing heavy, strong winds locked of trail etc.
