Down in the far south of Tajikistan, in Khatlon province, the land flattens into the wide floodplain of the Panj, the river that forms the border with Afghanistan. The site named Shahristoni Zoli Zar lies in this country, some eighteen kilometres from Farkhor, and it is one of many ancient settlement mounds scattered across the region. Southern Tajikistan was part of ancient Bactria, later the heartland of the Kushan empire, and the fields here have yielded Buddhist and early Islamic remains. A shahriston, in the old local sense, was the inner walled town, and the name suggests that this mound once held a proper urban core.
Honesty matters here: few detailed accounts of this particular site are published in English, and you should not expect signposts, fences or a visitor centre. What you get is a low tell rising out of cotton fields and irrigation channels, with the mountains of northern Afghanistan hazy on the southern horizon. Ask locally before walking on it; farmers will usually point the way and may offer tea.
Riding in Khatlon is hot, flat and dusty for much of the year. Summer temperatures climb well past forty degrees, so ride early, carry plenty of water and plan rest in the shade through the middle of the day. Roads between the district towns are mostly paved, with potholes, animals, slow trucks and the occasional checkpoint near the border. Keep your passport and permits handy, be polite at checks, and do not photograph border installations.
Farkhor is a district town of around twenty thousand people with fuel, a bazaar and simple chaikhanas serving plov, shashlik and fresh flatbread. Spring, when the irrigated fields are green and the air still mild, is the loveliest season, and autumn brings the cotton harvest. This is not a polished tourist trail. It is a ride through one of Central Asia's oldest farmed landscapes, along a river that has been a frontier for empires since Alexander, and the reward is the feeling of being somewhere very few travellers bother to stop.
