The M41 road is about 1,200 km longs and runs through Afghanistan, Uzbekistan, Tajikistan and Kyrgyzstan. It is informally known as the Pamir Highway.

The total route will take several days, as large parts of the road are often ripped away by landslides and avalanches, leaving only narrow, deeply rutted tracks of frozen mud. If you are planning to travel this road it's best to do so by 4WD vehicle.

One of the most hair-raising and spectacular sections runs through Pamirs, between Khorog in Tajikistan and Osh, 360 km to the north in Kyrgyzstan.

Especially the crossing of the 4,655 m (15,270 ft) high Ak-Baital pass is absolutely spectacular.

There is no accommodation in the area.
