Mustang retains much of its cultural autonomy and is administered by its own King or Raja, the 25th successor of his lineage. It is no wonder why it was opened for western visitors only after 1992. This magical journey in time begins with a short flight from Kathmandu to Pokhara, which on a clear day reveals splendid views from Langtang (7234m) to Dhaulagiri (8163m), an unforgettable experience. The actual trek begins from the rive side town of Birethanti, a short drive from Pokhara. From Birethanti here 2 days of gentle ascent will take you over terraced hills and through rhododendron forests, no mountain views unfortunately. There are, however glimpses of snow-capped splendour of Annapurna South (7219m). Soon the forests thin out and more vistas of the world's highest peaks of Dhaulagiri I (8167m), Annapurna I (8091m), Nilgiri (7061m), Fish Tail (6993m) and numerous other peaks reveal themselves. A relaxing day is spent on the way in Tatopani where refreshing natural hot springs welcome you. The world's deepest gorge can be seen on your way up to Kagbeni carved out by the mighty Kaligandaki River.

From here on you follow an ancient trade route through numerous villages along the windy river. This harsh and arid landscape offers its own imposing, rugged beauty. The hills are reminiscent of intricately coloured hues of blue, grey, white and yellow of Mandalas. Natural pigments from these hills are used to paint the Chortens and Gompas of this region forming a distinctive style. The village of Tangbe boasts an impressive Chorten striped by eight connected spirals. Across the river from Chusang eroded cliffs can be seen which resemble the pipes of a cathedral organ. You then climb to the valley of Nye La (12956), the highest pass on this trek. The descent from this point on takes you past one of the longest and most impressive Mani walls in Nepal while the walled city of Lo- Manthang can be seen shimmering over the horizon. The capital of the kingdom of Mustang, this city contains the richest surviving collection of 15th century Buddhist Mandalas in the world. Due to the destruction of temples in Tibet, the values of these Mandalas are immeasurable. The city and the surrounding valley can be explored on horseback the following day before you turn back to the flowing Kaligandaki.
